Introduction The Model 8900 Series Printers are compatible with a wide range of computers and application software. The printer menu structure enables you to select and alter the fundamental printer operating parameters to fit the requirements of your computer, its communication interface, and its application software. You can set these parameters via the operator control panel (see the following figure).
PAGE 17
Note: The Model 8900 Series Printers User’s Manual (Part No. 2557785-0002) explains the basic use of the operator control panel and its associated menu structure. The Setup/Test switch on the control panel lets you enter the setup/ test menu. This menu consists of the following submenus containing most of the printer setup parameters and test features. q Emulation mode — The emulation mode submenu lets you select an emulation mode and set its parameters.
PAGE 18
Model 8900 Series Emulation Modes The emulation mode determines how the printer responds to commands from the host computer and determines the specific set of commands to which the printer responds. For example, if you select the TI 880 emulation mode, the printer emulates the functions of the TI Model 880 Printer and responds to the set of commands designed for that printer. The emulation mode submenu lets you choose one of the following emulation modes or select the hexadecimal dump mode.
PAGE 19
Emulation TI880 TI855 Execute Commands ProPrinter Epson optional Proc Mode Auto LF DP NO NO WP YES YES Auto LF Auto CR Auto CR NO NO NO YES YES YES OFF Slashed 0’s Slashed 0’s LF/CR ON CR NO NO YES YES ON OFF LF/CR ON LF OFF Hexdump Auto LF ON OFF CR W/LF VT DC2 ON OFF Graphics ON OFF SO= Expand ON OFF emulation mode submenu TI 880 Emulation The TI 880 emulation submenu contains a group of setup parameters that can be set to either on or off.
PAGE 20
Line Feed and Carriage Return Upon Receipt of CR When on, this parameter causes the printer to perform both an LF operation and a CR operation upon receiving a CR command from the host computer. The default setting is OFF. Carriage Return Upon Receipt of LF, VT, or DC2 When on, this parameter causes the printer to perform a CR operation upon receiving any of the following commands. q Line feed (LF) — The printer moves the printhead down to the next print line and returns the carriage to the left margin.
PAGE 21
TI 855 Emulation The TI 855 emulation submenu contains the processing mode (WP/DP) parameter and the automatic line feed parameter, both of which can be set to match the requirements of your computer. The following paragraphs describe these parameters. Processing Mode The Tl 855 emulation mode lets you choose either of the following processing modes. q DP mode — uses commands (described in Chapter 6) similar to those used by a dot-matrix-type printer.
PAGE 22
Automatic Carriage Return This parameter is similar to the automatic LF parameter but is turned on for software that does not send a CR command at the end of each print line. If the printer advances from print line to print line but fails to perform a carriage return operation, you need to turn on the automatic CR parameter. The default setting is NO. Slashed Zeros When on, this parameter causes the printer to print slashes over all zeros to distinguish them from the letter O. The default setting is NO.
PAGE 23
Interface Parameters The interface parameters are values associated with serial communication interfaces. When using a serial interface, these parameters must be set to correspond to the capabilities of the host computer and the interface. The following figure shows the interface submenu and the following paragraphs describe the interface setup parameters.
PAGE 24
Baud Rate The baud rate is the rate (in bits per second) at which the interface transfers data. This parameters are 300, 600, 1200, 2400, 4800, 9600, or 19,200 bits per second. The default setting is 9600. Note: Data transferred over a serial interface consists of either 7- or 8-bit data bytes, each of which is accompanied by a start bit, a stop bit, and a parity bit. The values chosen for the data bits and parity parameters depend upon the requirements of the host. (See Chapters 3 and 10.
PAGE 25
XON/XOFF (transmit-on/transmit-off) For this busy-handling protocol, the printer sends a single XON (a DC1 control character) to indicate that it is ready to receive data and a single XOFF (a DC3 control character) to indicate that it is busy. The default setting is OFF. Robust XON/XOFF For the robust XON/XOFF protocol, the printer sends an XON (DC1 control character) approximately every 5 seconds to indicate that it is ready to receive data until either data is received or another busy condition occurs.
PAGE 26
ETX/ACK (end-of-text/acknowledge) For this busy-handling protocol, the host sends an ETX control character at the end of each data transmission, and the printer responds with an ACK control character to indicate that it is ready to receive additional data. If the printer is busy when it receives the ETX control character, it delays sending the ACK control character until the busy condition is cleared. The default setting is OFF.
PAGE 27
Miscellaneous Setup Parameters The miscellaneous setup parameters are mechanical and operational features that do not fit logically into the other setup categories. The following figure shows the miscellaneous setup parameters submenu and the following paragraphs describe these parameters. Character Set The Model 8900 Series Printers character set repertoire includes 6 standard character sets and 11 international language versions.
PAGE 28
Z-Axis Control The printer adjusts the printhead-to-paper clearance (z-axis) automatically when you load paper into the printer. In addition, the Z-AXIS parameter provides a manual z-axis adjustment. This selection invokes a display that lets you adjust the printhead in or out. You also can adjust the z-axis using an escape sequence described in the Appendix to this manual. Ribbon Type The RIBBON TYPE parameter lets you choose between color printing and black printing. The default setting is COLOR.
PAGE 29
Idle Delay At the end of a printing operation, if the paper is at top of form, the printer waits for more data and then, after a short delay (idle delay), moves the paper to the tear-off position. The IDLE DELAY parameter invokes a display that lets you adjust the idle delay to a value in the range of 300 milliseconds to 90 seconds. You can disable the idle delay feature by selecting a value above 90 seconds, in which case the LCD displays DISABLE.
PAGE 30
Graphics Printing Mode The BI-DIR GRAPHIC parameter lets you choose whether the printer prints graphics bidirectionally or from left to right only. The default setting is NO (print graphics from left to right only). LCD Language The LCD LANG parameter lets you set the control panel LCD to display its messages in English, French, German, or Spanish. The default setting is ENGLISH.
PAGE 31

Introduction This chapter describes the standard character sets and provides information about their use in the Model 8900 Series Printers. The printer can use any of several standard or optional character sets that can be selected via the operator control panel switches or via the host computer. These character sets provide all control characters and graphic characters necessary to implement the various printer emulation modes.
PAGE 34
Character Sets Your printer can use any of the following character sets. q US ASCII (default character set) q IBM PC1 q IBM PC2 q Nordic PC q ISO 8859/1 Multinational q IBM Multinational Note: The option ROM sockets on the printer logic board let you install additional character sets.
PAGE 35
The US ASCII Character Set The following table shows the U.S.A. Standard Code for Information Interchange (US ASCII) character set. This 7-bit character set is defined by the American National Standards Institute document ANSI X3.4 and is a variant of the ISO 646 character set.
PAGE 36
International ASCII Character Sets With a few exceptions, the international versions of the ASCII character set are identical to the US ASCII character set. These international versions can be selected via the operator control panel or via the host computer. The following table lists the variations between the US ASCII character set and the international versions.
PAGE 37
The IBM PC1 Character Set The following two tables show, respectively, the left half and right half of the the IBM PC 1 character set.

Control Characters Any character that causes the printer to perform a function is classified as a control character. Note that, although the Cl control characters are available in one of the standard character sets (ISO 8859/Multinational), your printer does not implement them. American National Standard ANSI X3.4 and International Standard ISO 646 define the C0 control characters based on the specific function performed by the character. The C0 control characters are divided into the following categories.

PAGE 49
Printer Commands The Model 8900 Series Printers receive commands from the host computer in the form of ASCII control character codes and escapesequence codes. In response to these commands, the printer performs one or more operations defined by the command set of the currently selected emulation mode. Chapters 4 through 8 describe the standard emulation modes. An example of a control character command common to all character sets and all emulation modes is the line feed (LF) character.
PAGE 50
Some escape sequence commands, valid for all emulation modes, are called global commands. These are special commands that select or control some basic or specially defined printer operation. Global Command Set The following table lists the global commands for the Model 8900 Series Printers. These commands are characterized by an intermediate control character DLE following the ESC character.
PAGE 51
Barcode Operations The barcode commands let you select a barcode font, set its parameters, and print any specified character in the equivalent barcode font. Note: If the barcode option is not installed, using this ESC sequence causes an ESC SEQ error. Set Barcode Parameters Escape sequence: ESC DLE B Hexadecimal: 1B 10 42 P 50 t t r r s s ETX 03 This command, where t = type, r = readability, and s = size, lets you select a barcode font and set its associated parameters.
PAGE 52
Print Barcode Text Escape sequence: ESC Hexadecimal: 1B DLE 10 B 42 C 43 text text ETX 03 This command lets you print a character or string of characters specified by the variable text. For example, to print the barcode equivalents of the numerals 0, 1, and 2 from the barcode font set selected by the Set Barcode Parameters command, enter the sequence ESC DLE B C 0 1 2 ETX.
PAGE 53
Print Oversize Character Escape sequence: ESC Hexadecimal: 1B DLE 10 C 43 C 43 text text ETX 03 This command prints the text contained within the command using the horizontal and vertical scale factors selected by the Set Oversize Characters command. The text variable is the character string to be printed in oversize characters.
PAGE 54
Selecting an Automatic Sheet Feeder Bin Escape sequence: ESC Hexadecimal: 1B DLE 10 EM 19 n n This command selects the ASF bin designated by the variable n, where n can range from 30 through 33 hex as follows: 0 (30H) = Load from current bin 1 (31H) = Select & load from bin 1 2 (32H) = Select & load from bin 2 3 (33H) = Load from current bin If the command is received with paper loaded from a friction feed path, the currently loaded form is ejected, and a form is loaded as defined by this command.
PAGE 55
Defining Raster Graphics Escape sequence: ESC Hexadecimal: 1B DLE 10 G 47 d1 d2 d1 d2 n1 n2 n1 n2 data data This command defines the dots-per-inch (DPI) density, the byte count of bit-image data, and bit-image data of those emulations that currently support raster graphics. The variable d1 d2 is DPI density, where d1 is LSB and d2 is MSB. The variable nl n2 is the byte count, where n1 is the LSB and n2 is the MSB. And data is bit-image data. All variables can range from 0 through 255.
PAGE 56
Selecting a Font Escape Sequence: ESC Hexadecimal: 1B DLE 10 f 66 n n This command allows you to access type styles not specifically supported by an emulation. This command selects the font designated by the variable n, where n can range from 0 through 254 decimal as follows: Font ID No.
PAGE 57
Selecting Characters Per Inch (cpi) Escape sequence: ESC Hexadecimal: 1B DLE 10 P 50 n n This command enables you to access natural pitches of a font that may not be specifically supported by an emulation. The command sets pitch according to the variable n, which can range from 30 through 33 hex. Unless specified otherwise, the emulation’s default HMI is used. Character pitch commands are effective immediately upon receipt, thus causing a pitch change within a line.
PAGE 58
The values of n for print mode selection are listed in the following table. Mode Hex Value Draft Text Letter Fast Draft 30 31 32 33 Selecting an International Character Set Escape sequence: ESC Hexadecimal: 1B DLE 10 R 52 n n The ASCII character set contains the C0 control codes, the uppercase and lowercase elements of the Latin alphabet, punctuation symbols, and other commonly used symbols.
PAGE 59
A character set is defined as 128 character positions. If more than 128 character positions are required, the set is divided in two and is designated left half (LH) for positions 1 through 127 and right half (RH) for positions 128 through 255. The MSB determines if the character set is placed in the left half (0 through 7F) or the right half (80 through FF) of the 8-bit character set table. An MSB of zero places the character set in the left half, MSB of one, in the right half.
PAGE 60
Adjusting the Print head Z-Axis Position Escape sequence: ESC Hexadecimal: 1B DLE 10 z 7A S S NN NN The Adjust Printhead Z-Axis Position command adjusts the printhead in or out by the number of steps specified by the variable NN, which is a two-digit ASCII value ranging from 00 through 99. See Appendix A for Application Instructions.
PAGE 61
If the paper is not at the top-of-form position when the printer receives the clear current path command, the printer executes a form feed operation before attempting to park tractor-fed paper and displays a prompt to PLEASE TEAR paper. If the PAPEROUT=BUSY option in the Setup/Test menu is set to YES, clearing (parking) the paper causes the printer to send a BUSY signal to the host, which may suspend communication.

Introduction The Texas Instruments Model 880 Printer emulation mode is the default emulation mode of your printer. If your printer includes color printing and the automatic sheet feeder, this mode lets you use the global commands described in Chapter 3 for operating these options. This mode also lets you use the global commands to select the international versions of the ASCII character set.
PAGE 66
Tl 880 Answer Message Function The TI 880 emulation provides, as a TI 880 feature, an answerback message (ABM) that can be programmed with a message of up to 20 characters. If a message is programmed, it is transmitted when the ASCII character ENQ is received. The ABM is stored in the printer’s nonvolatile memory and is programmable with an escape sequence when the ABM load setup parameter (ABM MSG LOAD) of the TI 880 emulation is turned on.

Margin Control Commands After the margins have been set, changing the line spacing does not affect the top and bottom margins. However, changing the character pitch shifts the left margin to the nearest column of the new pitch value. The right margin shifts in proportion to the change in pitch.
PAGE 79
Set Left Margin at Column N Escape sequence: ESC Hexadecimal: 1B [ 5B N N s 73 The variable N can be any value in the range of 1 through, the column immediately to the left of the current right margin value, as determined by the line width setting. For example, if the current right margin is at column 80, the valid range of N is 1 through 79. If N equals 0, the left margin equals the default value.
PAGE 80
Horizontal Motion Commands After the horizontal tab stops have been set, changing from standard print to expanded print does not affect the tab stop positions. However, changing the character pitch alters the tab stop positions in proportion to the change in pitch. Backspace Control character: Hexadecimal: BS 08 This command causes the printer to move the printhead one space to the left within the limits of the current left margin.
PAGE 81
Tab Right to Column N Escape sequence: ESC Hexadecimal: 1B [ 5B N N ‘ 60 The variable N can represent any column between the current print position and the currently set right margin position. Tab Right N Columns Escape sequence: ESC Hexadecimal: 1B [ 5B N N a 61 For any value of N that exceeds the right margin limit, the printer performs a line feed and carriage return and prints the next character in column one of the next line.
PAGE 82
Set Horizontal Tab Stop at Current Position Escape sequence: ESC Hexadecimal: 1B H 48 Clear Horizontal Tab Stop at Current Position Escape sequence: ESC Hexadecimal: 1B [ 5B 0 30 g 67 Vertical Motion Commands Vertical tab stops define the line numbers at which the paper stops when performing vertical tab operations. After vertical tab stops have been set, any change of the vertical pitch causes a proportional change in the vertical tab stop positions.
PAGE 83
Tab Vertically Control character: Hexadecimal: VT 0B If the printer is configured to perform a carriage return upon receiving a VT control character, this command causes the printer to print the current line, advance the paper to the next vertical tab stop, and perform a carriage return. If the printer is not configured to perform a carriage return upon receiving VT, the printer prints the current line and advances the paper to the next vertical tab stop without performing a carriage return.
PAGE 84
Set Vertical Tab Stops Escape sequence: ESC Hexadecimal: 1B [ 5B N1...N16 N1...N16 v 76 Escape sequence: ESC Hexadecimal: 1B 1 31 n1...n16 n1...n16 NUL 00 These commands set vertical tab stops at the lines specified by the variables N1 through N16 or n1 through n16, where each of the variables N1 through N16 or n1 through n16 can be any value in the range of 0 through 113. The command ESC 1 n1...n16 NUL also clears all previously set tab stops.

Model 855 WP Command Descriptions The following paragraphs describe the Model 855 WP emulation commands. The command formats are listed following each command description. Many of the escape-sequence commands contain one or more variables to specify various command parameters. These variables are italicized in the command formats to indicate that they can be set to more than one value. Printer Operation Commands These commands allow the host computer to control some basic printer functions.
PAGE 102
Select Unidirectional Printing Escape sequence: ESC Hexadecimal: 1B > 3E This command causes the printer to print all subsequent characters in the forward (left-to-right) direction only. Cancel Unidirectional Printing Escape sequence: ESC Hexadecimal: 1B < 3C This command causes the printer to resume normal bidirectional printing. Select Reverse Printing Escape sequence: ESC Hexadecimal: 1B 6 36 This command causes characters received from the host to be printed in reverse order.
PAGE 103
Form Format and Font Selection Commands The form format commands let you select and set some form-related parameters. The font selection command lets you choose between the two standard fonts and any installed optional fonts. The standard fonts for the Model 8900 Series Printer are Courier and Gothic. Residing in printer ROM, these fonts can be selected via the control panel or by the host computer. Optional fonts include Prestige Elite and Presentor.
PAGE 104

Set Bottom Margin at Current Position Escape sequence: ESC Hexadecimal: 1B 2D If the form length does not exceed the bottom margin, the bottom of the form is the same as the bottom margin setting.
PAGE 106
Horizontal Motion Commands The following paragraphs describe the commands for horizontal motion and horizontal tab functions in the Model 855 WP emulation mode. Backspace Control character: BS Hexadecimal: 08 This command causes the printer to move the printhead one HMI position to the left. The next character printed following a BS command overstrikes the most recently printed character. In the backward print mode, each BS control character moves the printhead to the right one HMI position.
PAGE 107
q If the expanded print mode is active, the CR command resets the printer to the normal print mode. q If the automatic line feed function is active, the CR command causes the paper to advance one print line. Move Back 1/120 inch Escape sequence: ESC Hexadecimal: 1B BS 08 This command moves the print position 1/120 inch to the left.
PAGE 108
Vertical Motion Commands Vertical tab stops define the line numbers at which the paper stops when performing vertical tab operations. After vertical tab stops have been set, any change of the vertical pitch causes a proportional change in the vertical tab stop positions. Line Feed Control character: LF Hexadecimal: 0A This command moves the paper forward one line position without performing a carriage return. The VMI determines the distance from one line to the next.
PAGE 109
Move Up One Line Escape sequence: ESC Hexadecimal: 1B LF 0A The line space is the distance defined by the VMI or the distance set via the Form Config switch on the control panel. Move Up One-Half Line Escape sequence: ESC Hexadecimal: 1B D 40 When one-half line space is a fractional number of 1/144 inch steps, the printer truncates the number of steps to a whole number.
PAGE 110

Set Most Significant Bit to Zero Escape sequence: ESC Hexadecimal: 1B = 3D Some computers, when sending characters from 7-bit character sets, automatically set the most significant bit (MSB) of each character to 1.
PAGE 164
Cancel Most Significant Bit Control Escape sequence: ESC Hexadecimal: 1B # 23 This command cancels printer control of the received character MSB and returns control to the computer. This enables the computer to select characters from either the GL half or the GR half of the selected printer character set. Select Unidirectional Printing for One Line Only Escape sequence: ESC Hexadecimal: 1B < 3C This command selects unidirectional printing for one line only.
PAGE 165
Form Format Commands The form format commands let you set the form length in either lines or inches. These commands also let you enable or disable the automatic perforation skip feature. Set Form Length to n Lines Escape sequence: ESC Hexadecimal: 1B C 43 n n This command sets the form length to the number of lines specified by the variable n in the current line spacing. This command also sets the top-of-form position to the current line. The variable n can be any value in the range of 1 through 127.
PAGE 166
Example. If the current form length setting is 66 lines and the current line spacing is 6 lpi, setting the value of n to 6 causes the printer to do the following. 1. Print 60 lines on the current form. 2. Skip 6 lines at the bottom of the current form. 3. Print the next text line at the first print line position of the following page. Invoking any of the commands ESC O, ESC C n, or ESC C NUL n cancels the Select Automatic Perforation Skip command.
PAGE 167
Margin Control Commands The margin control commands let you set parameters related to the left, right, bottom, and top margins and control print justification and text centering. Select Left Margin Justification Escape sequence: ESC Hexadecimal: 1B a 61 NUL 00 This command causes the printer to justify any subsequent text to the left margin.
PAGE 168
Set Left Margin at Column n Escape sequence: ESC Hexadecimal: 1B 1 6C n n This command sets the left margin at the position specified by the variable n. The minimum distance between the left and right margins is the width of one expanded 10 cpi character. Invoking this command clears all previously set horizontal tab stops and all previous characters from the current print buffer contents.
PAGE 169
Horizontal Motion Commands The horizontal motion commands control the horizontal motion of the printhead, including direction and distance of each movement. The following paragraphs describe the horizontal motion commands. Backspace Control character: BS Hexadecimal: 08 This command causes the printer to print the current print buffer contents and then move the print position one character to the left.
PAGE 170
Set Absolute Print Position Escape sequence: ESC Hexadecimal: 1B $ 24 n1 n1 n2 n2 This command sets the first character position of subsequently printed text at 1/60 inch or some multiple of 1/60 inch from the currently set left margin. The variables n1 and n2 form a two-byte hexadecimal value that specifies the absolute print position in 1/60 inch increments.
PAGE 171
Set Horizontal Tab Stops Escape sequence: ESC Hexadecimal: 1B D 44 n1...n32 n1...n32 NUL 00 This command clears all previously set horizontal tab stops and sets a new tab stop at each of the columns specified by the variables n1...n32. Each of the variables n1 and n2 can be any value in the range of 1 through 127 for a 7-bit character set and 1 through 232 for an 8-bit character set.
PAGE 172
Form Feed Control character: FF Hexadecimal: 0C This command causes the printer to print the current print buffer contents and then move the printhead to the first print line of the next form. Tab Vertically Control character: VT Hexadecimal: 0B This command advances the print position vertically to the next vertical tab stop in the currently selected vertical tab channel (VTC). If no VTC has been previously selected, the printer automatically uses VTC 0.
PAGE 173
Select Vertical Tab Channel Escape sequence: ESC Hexadecimal: 1B / 2F c c This command selects one of the eight preset VTCs. The printer subsequently uses this VTC for all vertical tab operations. The variable c specifies the VTC number (0 through 7). Set VTC Tab Stops Escape sequence: ESC Hexadecimal: 1B b 42 c c n1...n16 n1...n16 NUL 00 This command sets up to 16 vertical tab stops (in the current line spacing) for the VTC specified by the variable c.
PAGE 174
Character Pitch Commands The character pitch commands let you choose between 10 and 12 cpi or adjust the horizontal spacing between characters. The character pitch is the horizontal distance from the center of one character to the center of the next character. Set Character Pitch to 10 cpi Escape sequence: ESC Hexadecimal: 1B P 50 This command selects 10 cpi character pitch and cancels 12 cpi character pitch if it has been previously selected.
PAGE 175
Line Spacing Commands The line spacing commands let you choose between line spacing values of 6 or 8 lpi or any of several fractional line spacing values. The line spacing is the vertical distance between print lines. Set Line Spacing to 6 lpi Escape sequence: ESC Hexadecimal: 1B 2 32 This command sets the line spacing to 6 lpi (the default value) for all subsequent line feed operations.
PAGE 176
Set Line Spacing to n/216 Inch Escape sequence: ESC Hexadecimal: 1B 3 33 n n This command sets the line spacing to a value in the range of 0/216 through 255/216 (0 through 1.18) inches for subsequent line feed operations. Character Set Commands The character set commands enable you to select and use the standard Epson FX character sets or international versions of these character sets. The following paragraphs describe the character set commands.
PAGE 177
Select International Character Set Escape sequence: ESC Hexadecimal: 1B R 52 n n This command selects, for either draft or LQ printing, the international version of the ASCII character set specified by the variable n. The variable n can be any of the following values.
PAGE 178
Enable Character Positions 0-31 and 128-159 as Printable Characters Escape sequence: ESC Hexadecimal: 1B I 49 SOH 01 This command enables the printer to treat the characters in character positions 0-31 (C0 control characters) and 128-159 (C1 control characters) as printable characters.
PAGE 179
Cancel Expanded Print Control character: DC4 Hexadecimal: 14 This command cancels the expanded print mode previously selected by the Select Expanded Print for One Line commands (SO or ESC SO). However, this command does not affect the expanded print mode invoked by the Select Expanded Print command ESC W SOH or the Select Master Print Mode command (ESC ! n).
PAGE 180
These commands cause the printer to print characters at about 60 percent of their normal widths. For example, for a character pitch of 10 cpi, one inch of text contains about 17 characters instead of the normal 10. These commands are valid for either draft or LQ printing.
PAGE 181
Cancel Boldface Print Escape sequence: ESC Hexadecimal: 1B H 48 Select Shadow Print Escape sequence: ESC Hexadecimal: 1B E 45 Cancel Shadow Print Escape sequence: ESC Hexadecimal: 1B F 46 Select Superscript Print Escape sequence: ESC Hexadecimal: 1B S 53 NUL 00 This command selects the superscript print mode for either draft or LQ printing. After receiving this command the printer prints each subsequent character in the upper part of the character space at about two-thirds its normal height.
PAGE 182
Select Italic Print Escape sequence: ESC Hexadecimal: 1B 4 34 This command causes the printer to print characters from the Epson italic character set for either draft or LQ printing. This command is valid even if the printer has received an ESC t SOH command to invoke the Epson extended graphics character set; however, character graphics cannot be italicized.
PAGE 183
To select a valid combination of the listed character pitches and print modes, choose the items you wish to combine and add their values to find the correct value of n. After finding the decimal value of n, convert this value to its hexadecimal equivalent for use in the escape sequence. For example, to select 12 cpi, expanded, underlined text characters, add the decimal values 1, 32, and 128 to obtain the sum, 161 (the value of n). The hexadecimal equivalent of 161 is A1 (from an 8-bit character table).
PAGE 184
Select 9-Pin 60 dpi Graphics Escape sequence: ESC Hexadecimal: 1B ^ 5E NUL 00 n1 n1 n2 n2 This command causes the printer to print 9-pin graphics at 60 dpi. Select 120 dpi Graphics Escape sequence: ESC Hexadecimal: 1B L 4C n1 n1 n2 n2 This command selects the 8-pin, 120 dpi graphics mode for the horizontal distance specified by the two-byte variable n1 n2.
PAGE 185
Select Graphics Mode m Escape sequence: ESC Hexadecimal: 1B * 2A m m n1 n1 n2 n2 This command selects the graphics mode specified by the variable m for the horizontal distance specified by the two-byte variable n1 n2. The variable m can be any of the following values.

Introduction This chapter describes the communication interfaces and provides information about their use with your printer. The communication interface transfers data in a fixed and orderly manner between the host and the printer. Communication interfaces are of two general types: parallel and serial. Parallel interfaces transfer all bits of a data byte simultaneously. Serial interfaces transfer data in bit-serial fashion, one bit at a time.
PAGE 195
The following figure shows simplified block diagrams of two types of data-communication systems and their associated communication interfaces. long-distance system host RS-232-C serial interface modem modem telephone lines RS-232-C serial interface printer local system host local printer parallel interface communication interfaces (simplified block diagrams) The long-distance system typically uses telephone lines to transfer data from the host to the printer.
PAGE 196
The following figure shows a simplified block diagram of the printer receive buffer and the data path between the host and the print mechanism. printer host communication interface receive buffer print mech. printer receive buffer and associated data path The host transfers characters in the form of 7-bit or 8-bit data bytes, depending on which character set is selected. To ensure that no data is lost between the host and the printer, all data-transfer operations involve the following steps. 1.
PAGE 197
Parallel Communication Interface The parallel communication interface uses a 36-pin connector (shown in the following figure) that transfers both data and control signals between the printer and the host computer. The parallel interface connector is located at the rear of the printer and provides bail latches to secure the interface cable connector. The table on the following page lists the parallel interface signals, their names, their pin assignments, and their sources (host or printer).

PAGE 199
Data Signals Character transfers from the host to the receiver consist of 8-bit data bytes (DATAl through DATA8) traveling in parallel over the eight data lines. DATAl is the least significant bit and DATA8 is the most significant bit. If a 7-bit character set has been selected, the DATA8 line remains low for all data transfer operations. Data Strobe Signal The data strobe (STROBE-) is a host-generated pulse that clocks data into the printer receive buffer.
PAGE 200
Busy Signal This active-high signal from the printer indicates that the printer is busy and cannot accept additional data. During data-transfer operations, the leading edge of the host-generated strobe signal activates BUSY for each character-transfer cycle. The printer sends an acknowledge pulse and deactivates BUSY at the completion of each character-transfer operation (unless the printer is otherwise busy). BUSY is active (high) under any of the following conditions.
PAGE 201
Paper-Empty Signal The paper-empty (PE) signal from the printer indicates that the paper supply is empty. The printer activates this signal in combination with the fault signal to indicate the paper-empty condition to the host. Select Signal The select (SLCT) signal from the printer indicates to the host that the printer is online and ready to receive data. The completion of either a normal power-up operation or a host-generated initialization cycle activates SLCT.
PAGE 202
The following figure shows the timing sequence for host-to-printer character-transfer operations. The table on the following page lists the timing requirements for the operation. ▲ ▲ DATA1-8 c ▲ e d ▲ b f g ▲ a valid data ▲ h valid data STROBE- BUSY ACK▲ reference line parallel data timing sequence The reference points, a through h in the preceding figure, are keyed to the table on the following page and to the following character-transfer sequence. 1.
PAGE 203
3. The printer activates ACK- (e) to signal the host that the receive buffer has received the character. 4. If the character does not fill the receive buffer, the printer deactivates BUSY and ACK- (f) to notify the host that the transfer operation is complete. The host can then initiate another data-transfer cycle. If a character-transfer cycle fills the printer receive buffer, BUSY remains active until the buffer empties to the ready point.
PAGE 204
Parallel Interface Timing Requirements (continued) Ref. Timing Requirements f Trailing edge must occur before the host can strobe the next character into the receive buffer. For normal write cycles (receive buffer not full), this occurs at 10 µs min., 500 µs nom., and 1000 µs max. after the leading edge of STROBE-. DATA1-8 g The host writes the next character to the interface. This can occur at any time after the data stabilization time and hold time of the previous character have elapsed.
PAGE 205
Error Conditions FAULT- and PE are printer status lines. The printer activates FAULTto indicate a mechanism failure, such as a paper jam, and deactivates it when the error is corrected. After the paper supply is depleted, the printer activates both PE (paper empty) and FAULT- to indicate the paper-empty condition. Reloading paper causes the printer to deactivate the signals. Activation of either FAULT- or PE also activates BUSY to indicate that the printer cannot receive data.
PAGE 206
Serial Interface Connector The serial communication interface transfers either 7-bit or 8-bit character information in an asynchronous, bit-serial format. This format is useful for transferring data over long distance lines via data communication devices such as modems, but it can also be used to transfer data directly between the host and the printer. The following table lists the serial interface signals.
PAGE 207
Interface Signal Descriptions The following paragraphs describe the serial interface signals. Protective Ground The protective ground (PG) line is connected directly to the power cord ground to provide protection for the equipment and personnel. Signal Ground The signal ground (SG) line is connected to the printer power supply ground to provide a common reference level for all interface signals except protective ground.
PAGE 208
Clear to Send Signal The host computer generates the clear to send (CTS) signal to indicate that it can receive data from the printer. In the DIRECT CONNECT mode, the printer ignores this signal. In the MODEM CONNECT mode, CTS must be on for the printer to send data. If the interface cable does not provide a connection to this pin, the printer holds CTS in its on state. Data Set Ready Signal The host activates the data set ready (DSR) signal to enable the printer to send and receive data.
PAGE 209
Interface Data Transmission Rate Because data-transfer operations on the serial interface occur in a bit-serial fashion, the data transmission rate is measured in bits per second, commonly called the baud rate. To provide compatibility with a variety of systems, your printer offers the following range of baud rates.
PAGE 210
In addition to the data bits, each character contains the following bits. q Start bit — A bit immediately preceding the character bits that signals the start of the asynchronous data transmission. q Parity bit — A bit immediately following the character bits that allows the printer to check the integrity of the received data. The setup menu allows you to select even, odd, mark, space, or no parity checking.
PAGE 211
Serial Interface Busy-Handling Protocols The serial interface provides several methods for the printer to indicate its ready and busy conditions. The communication interface menu, described in Chapter 2 of this manual, allows you to select any of these methods during printer setup. The following paragraphs describe the serial interface busy-handling protocols.
PAGE 212
This busy-handling protocol should not be selected for an emulator that requires that ETX be used as a graphics character or as part of a printer command. Direct-Connect Busy-Handling Protocols The control panel menu structure offers the following choices of busy-handling protocols for use with a serial interface connected directly to the host.
PAGE 213
RS-422 Communication Interface The RS-422 serial communication interface handles data structures of the same format as those for the serial communication interface. However, the RS-422 interface can transfer data over distances of up to 4000 feet (1219 meters) with minimal noise interference. Current Loop Communication Interface The current loop (TTY) interface uses a four-wire, passive, neutral current loop which does not interfere with the standard serial interface.

A Application Instructions Z-Axis Adjustment Escape Sequence Introduction The Model 8900 Series Printers sense top, left, and right edges plus thickness when a form is loaded. These settings provide the location of printout on the form such as top, bottom, left, and right margins and locations of labels or uneven edges. ! Caution: Some forms or form sets may have isolated stick-on labels or some areas that contain more copies than others as illustrated in the following figure.
PAGE 215
isolated labels uneven edges Considerations for Z-Axis Adjustments The following considerations (plus DOs and DON’Ts) should be given for Z-axis adjustments. ! Caution: This escape sequence is designed for use by technically oriented software users to print on forms with multiple thicknesses and is not intended for the casual user. Damage to the printer can occur by misuse of this command. q Do not print across any boundary of a label or uneven edge (top, bottom, left, or right).
PAGE 216
q Valid Z-axis adjustment values are 00 through 99 from the automatic Z-axis initialization adjustment (00) in positive or negative directions (-99 through +99). q Note the location of the Z-axis initialization whenever paper stock is changed or tractors are moved, to determine the 00 calibration and corresponding number of sheets and form thickness.
PAGE 217
Escape Sequence — Z-Axis Printhead Position Escape sequence: ESC Hexadecimal: 1B DLE 10 z 7A S S NN NN where: S = “+” or “-” as the sign of the displacement (positive or negative). NN = ASCII values of the two digit number of the range from initialization. Note: The escape sequence ESC DLE z, followed by any code, other than specified for the next three characters, calibrates the printhead to the Z-axis initialization.
PAGE 218
880 Emulation Commands For 880 emulation, send the following code and text. Note: For this example, printing can be continuous, within the margins, on every line of the page. ESC [ 7 ; 54 r — prints first print line on line 7, last print line at line 54. ESC [ 11 ; 75 s — sets first print column at column 11, and last print column at column 75. Send text, then at the end of line 43 send ESC [ ; 48 s — sets the right print column to column 48.
