Using the Controls The EFP9800 printer includes the following buttons: • Paper Feed button used to advance paper. • Reset button used to initialize the printer. Caution Pressing the Reset button initializes the printer, causing any downloaded fonts to be lost.
Operating the Printer Changing Paper The EFP9800 features simple paper loading that is quick and efficient, saving both time and paper. Caution Do not operate the printer if it runs out of paper. The printer will continue to operate, but data may be lost and the printhead may be damaged.
Operating the Printer Changing Receipt Paper Note: Use these instructions if you are printing receipts only. If you are printing both receipts and a journal (record of transactions), or a journal only, see “Changing Receipt/Journal Paper” later in this section. Note: All EFP9800 Series printers have a receipt journal take up spool assembly factory installed that is not always required or utilized by the client.
Operating the Printer Removing the Old Receipt Paper Roll 2–4 1. Open the rear cover. 2. Open the clamshell. 3. Remove the used receipt paper roll.
Operating the Printer Loading the New Receipt Paper Roll 1. Drop the new roll into the bucket and pull out several inches. 2. Lay the end of the paper out over the top of the slip table, then close the rear cover and the clamshell.
Operating the Printer Changing Receipt/Journal Paper Note: Use these instructions if you are printing both receipts and a journal (record of transactions) or a journal only. If you are printing receipts only, see “Changing Receipt Paper” earlier in this section. Removing the Printed Journal 2–6 1. Open the rear cover. 2. Tear the paper off below the last journal entry. 3. Open the clamshell. 4. Slide the printed journal off the take-up core and set it in a safe place. 5.
Operating the Printer Loading the New Receipt/Journal Paper Roll 1. Drop the new receipt/journal roll into the bucket and pull out about 10 inches (25 cm) of paper. The paper should not extend farther than the back of the printer cabinet. 2. Close the clamshell. 3. Place the end of the journal ply between the halves of the take-up assembly. If you are printing a journal only, continue with step 4.
Operating the Printer Verifying Checks Follow this procedure to verify checks on printers with the MICR check reader option. The printer’s Magnetic Ink Character Reader (MICR) check reader reads the magnetic ink characters on the check in order for the host computer to verify that the check is good. Note: 2–8 Verify the check before you validate it. For more information, see “Validating Slips and Checks” later in this section.
Operating the Printer 1. Insert the check from the front, face up, with the MICR characters to the right, as shown. 2. Slide the check toward the back of the printer along the right side until it covers both sensors. The Slip In LED turns on when both sensors are covered, indicating that the check is inserted properly. The printer reads the magnetic characters on the check.
Operating the Printer Printing on Slips and Checks There are several types of transactions for which you may print on a slip or check. These include some credit card transactions, merchandise return forms, electronic funds transfers and check printing (printing the date, payee, and amount on the check). The EFP9800 can print on slips and forms up to five-parts thick (the receipt is included as one or two of the parts depending if it is one-ply or two-ply).
Operating the Printer 4. Position the slip/check so that the top is protruding from the top of the printer. The Slip In LED flashes green. When the slip/check is inserted properly, the Slip In LED is lit steadily. Depending on your printer setup, the printer may automatically begin printing, or you may have to perform the action programmed for your printer, such as pressing a particular keyboard key. Follow the instructions from the host computer. 5.
Operating the Printer Validating Slips and Checks The EFP9800 can print on slips and forms up to five-parts thick (the receipt is included as one or two of the parts depending if it is one-ply or two-ply). For more information on the types of slips and forms you can use, see “Ordering Paper and Supplies” in section 1. Follow this procedure to validate slips and checks. Note: Do not use this procedure for check verification. See “Verifying Checks” earlier in this section.
Operating the Printer 4. Remove the slip/check once it is fed back out and then follow the instructions from the host computer to finish the transaction. Changing the Ribbon Cassette Change the ribbon cassette when the print is too light or the ribbon is frayed. 1. Open the cassette cover. 2. Slide the carriage assembly (assembly that holds the printhead) to the center of the printer.
Operating the Printer 3. Pull the used ribbon cassette out of the printer and discard it. Be careful not to bump or damage the Form Out sensor while you remove the ribbon cassette. 4. Snap in the new ribbon cassette, and close the cassette cover. Caution Do not remove the mylar shield on the ribbon cassette. It protects against smudging. The ribbon cassette will be ruined if it is removed.
Operating the Printer Replacing the Printhead The impact printhead is extremely reliable. However, it may need to be changed depending on the use of the printer. Printhead replacement is required if it is tearing or fraying the ribbon, or if some dots print lighter than others. Call a service representative for printhead replacement. Adjusting the Paper Low Sensor Before adjusting the paper low sensor, make sure the power is off.
Operating the Printer Procedure The paper low sensor lights the paper low/out LED when the paper roll is almost empty. You can raise or lower the paper low sensor assembly to change the amount of paper left on the roll when the sensor lights the paper low/out LED. Raise the assembly by turning the screw counterclockwise to signal paper low earlier (more paper left on the roll). Lower the assembly by turning the screw clockwise to signal paper low later (less paper left on the roll).
Section 3 Diagnostics and Print Tests The following diagnostic tests are available for the EFP9800: • Level 0 Diagnostics: Performed during the startup cycle and each time the printer is reset. • Level 1 Diagnostics: Performed using DIP switches or the Paper Feed button. • Diagnostic Print Tests. Level 0 Diagnostics The printer automatically performs Level 0 diagnostics each time it is turned on. Level 0 diagnostics include the following: • All motors and solenoids are turned off.
Diagnostics and Print Tests If both the red Paper Status and the green Slip In LED’s are steadily illuminated, it is an indication that the NVRAM has failed. When the last step of the Level 0 diagnostics is complete, the Paper Feed button is enabled and the printer is ready for normal operation. If the printer does not complete Level 0 diagnostics, the LED’s flash to indicate the problem. See “Getting Service” in section 4.
Diagnostics and Print Tests After changing the DIP switch settings, cycle the printer by pressing the Reset button off and then on again. The green Online LED flashes when the printer cycles. Caution If you are changing the switch settings for a function or test, be sure you choose the correct settings to avoid accidentally changing the settings for another function or test.

Section 4 When Something Goes Wrong The EFP9800 printer is a simple, generally trouble-free printer, but from time to time minor problems may occur. For example, the power supply may be interrupted or the paper may jam. For some problems, the printer communicates the information to the host computer and relies on the application to indicate the problem. You’ll be able to fix most problems easily. For some problems, you will need to contact a Unisys-authorized service representative.
When Something Goes Wrong Printer Not Operating Cause Action Power cable not connected properly Check all cable connections. Check that the host computer and power supply are both on. The power supply is turned on by plugging it into an outlet. Paper jam in receipt/journal or slip station Open the cover and the clamshell. Push the carriage away from the paper jam. Remove any jammed paper or other obstructions. Press the Reset button to remove error status.

When Something Goes Wrong 4–8 3255 4073–002
Section 5 Communication In order for a receipt or slip to be printed, a program must be in place that translates the data from the host computer into a language the printer can understand. This program must tell the printer exactly how to print each character. This section describes how to create such a program or modify an existing one. Interfaces In order for the printer to communicate with the host computer, a communication link must be set up.
Communication Exit the COPY mode by typing: CTRL Z [Enter] Once the computer knows to direct data from any print command to the proper port, commands can be sent from any software program. Using BASIC to Send Commands In BASIC, printer commands are sent as a string of characters preceded by the PRINT command. For example, PRINT#1, CHR$(&H0A) (where #1 is the file number of a communication line opened by the OPEN “COM1:” command. For more information, see your BASIC documentation.
Communication • For XON/XOFF, a particular character is sent back and forth between the host computer and the printer to regulate the communication. • For DTR/DSR, changes in the DTR/DSR signal coordinate the information flow. The RS-232C version of the EFP9800 offers the standard options which are selected with the DIP switches. For more information on these settings, see “Setting Switches” later in this section.
Communication DTR/DSR Protocol The DTR signal is used to control data transmission to the printer. It is driven low when the printer is ready to receive data and driven high when it cannot accept any more data. Data is transmitted from the printer after it confirms that the DSR signal is low. RS-232C Interface Connectors This section describes the pin settings for the RS-232C connectors and interface parameters. The RS-232C parameters are selected by setting the DIP switches on the PC board.

Many commands throughout this section include page mode functions.
EFP9800 ESC/POS Commands Horizontal Tabs: Skip to Next Tab Stop Skips to the next horizontal tab stop. The command is ignored unless the next horizontal tab position has been defined. Default tab stops are every 8 columns. Hexadecimal Decimal 09 ASCII 9 HT Standard Mode If there are no more tab stops before the end of a line when this command is received, the print starting position will be set to the beginning of the next line. In other words, a line feed will be performed.
EFP9800 ESC/POS Commands Eject Slip Prints the data in the buffer and ejects the slip. Hexadecimal Decimal ASCII 0C 12 FF Standard Mode • Enabled only when slip is selected for printing. • Slip is ejected to the length set by the Set Slip Eject Length command (1B 43). If this length is not set, the slip is completely ejected. • Receipt or journal paper from the paper roll is not ejected even if it is also selected.
EFP9800 ESC/POS Commands Cancel Print Data in Page Mode Deletes all the data to be printed in the “ page” area. Any data from the previously selected “ page” area that is also part of the current data to be printed is deleted. This command is only used in page mode. For more information see “ Page Mode” later in this section. Hexadecimal Decimal ASCII 18 24 CAN Set Right-Side Character Spacing Sets the right-side character spacing to n x (fundamental calculation pitch).
EFP9800 ESC/POS Commands Page Mode Two types of fundamental calculation pitch are used to set the right-side character spacing, depending on the value of the Select Print Direction in Page Mode command (1B 54 n). For more information see “ Page Mode” later in this section. • If 1B 54 n = 0 or 2, the horizontal direction of the fundamental calculation pitch is used. • If 1B 54 n = 1 or 3, the vertical direction of the fundamental calculation pitch is used.
EFP9800 ESC/POS Commands Underlined and Double-Wide A0 A1 Underlined, Double-Strike, and Double-Wide A8 A9 Underlined, Double-High, and Double-Wide B0 B1 Underlined, Double-Strike, Double-High, and Double-Wide B8 B9 Note: Underlines cannot be printed for 90 degree clockwise rotated characters or for spaces set by the Horizontal Tab, Set Absolute Starting Position, or Set Relative Print Position commands.
EFP9800 ESC/POS Commands Select Print Mode(s) (for Windows™ Printer Drivers) Selects the print mode(s) specified by the value of n as outlined below. The default is 1. This command is intended for use with Windows printer drivers developed with the Windows unitool. This command is nearly identical to Select Print Mode(s) (1B 21) except that the bits for Double-Strike and Underline are ignored.
EFP9800 ESC/POS Commands Standard Mode The horizontal direction of the fundamental calculation pitch is used to set the print starting position from the beginning of the line. Page Mode Two types of fundamental calculation pitch are used to set the print starting position from the beginning of the line, depending on the value of the Select Print Direction in Page Mode command (1B 54 n). For more information see “ Page Mode” later in this section.
EFP9800 ESC/POS Commands Set Line Spacing Sets the line spacing to n x (fundamental calculation pitch). The default value is n = 24. The command is only available for the paper selected using the Select Paper for Setting Line Spacing command (1B 63 31). See the Set Fundamental Calculation Pitch command (1D 50). Hexadecimal Decimal ASCII Value of n 1B 33 n 27 51 n ESC 3 n 0-255 Standard Mode The vertical direction of the fundamental calculation pitch is used to set the line spacing.
EFP9800 ESC/POS Commands Select Peripheral Device Selects or cancels a peripheral device designated by the value of n. When the printer is not selected, it reads all data but performs nothing except the Real Time Status Transmission or Real Time Request to Printer commands. Even though the printer is not selected, it may go offline through manual printer operation. Use internal switch pack settings to determine which value of n is selected. For more information, see “ Switch Entry Mode” in section 3.
EFP9800 ESC/POS Commands Set Slip Eject Length Sets the slip eject length to n lines. (When n = 0, no length is set.) Changes in line spacing do not affect the slip eject length. The length set by this command is used only when the Eject Slip command (0C) is performed. This command is only effective in the standard mode. Hexadecimal Decimal ASCII Value of n 1B 43 n 27 67 n ESC C n 0 - 255 The maximum slip eject length is 40 inches.
EFP9800 ESC/POS Commands Print and Feed Paper Prints the data in the buffer and feeds the paper a distance of n x (fundamental calculation pitch).

In uni-directional printing, the printer prints from right to left.
EFP9800 ESC/POS Commands Standard Mode The default value of n is 0. Page Mode The default value of n is 1. For more information see “ Page Mode” later in this section. Note: Only the lowest bit of n is effective. When n is even, uni-directional printing is turned off and when n is odd, uni-directional printing is turned on. Set Printing Area in Page Mode Sets the position and size of the printing area in page mode. For more information see “ Page Mode” later in this section.
EFP9800 ESC/POS Commands Keep the following notes in mind for this command. 6– 20 • The fundamental calculation pitch depends on the vertical or horizontal direction. • The maximum printable area in the x direction is 400/160 inches. • The maximum printable area in the y direction is 1408/144 inches.
EFP9800 ESC/POS Commands Set Relative Print Position Sets the print starting position based on the current position, in the fundamental calculation pitch. The distance (in inches) from the current position is calculated as: [N x (fundamental calculation pitch)]. See the Set Fundamental Calculation Pitch command (1D 50). Pitch N to the right is calculated as: (n1 + n2 x 256). Pitch N to the left is calculated as: (n1 + n2 x 256) = 65535 - N.
EFP9800 ESC/POS Commands The command is effective only at the beginning of a line. It is ignored when n is out of range. Hexadecimal Decimal ASCII Value of n 1B 61 n 27 97 n ESC a n 0 = Left Justify (default) 1 = Center 2 = Right Justify The settings do not apply in page mode. Select Print Paper(s) Selects the paper for printing. (See the following table.) The command is effective only at the beginning of a line. It is ignored when n is out of range. The default is n = 1.
EFP9800 ESC/POS Commands Notes: • When the paper selection changes, if slip or validation was previously selected, the slip or validation paper is ejected. • When either slip or validation is selected, the printer waits for the paper to be inserted. • When both slip and receipt/journal paper are selected at once, printing on the pressure roll is possible only when pressure-sensitive paper is used. • If the previously selected paper is re-selected, no action takes place.
EFP9800 ESC/POS Commands Select Paper Sensor(s) to Stop Printing Selects the paper sensor(s) used to stop printing when the paper-end is detected. The printer finishes printing the current line and feeds the paper before stopping. After a paper sensor is enabled, printing is stopped only when the corresponding paper is currently selected. If multiple sensors are enabled, printing stops when any one detects a paper end.
EFP9800 ESC/POS Commands Enable/Disable Paper Feed Button Enables or disables the Paper Feed button. Note: Hexadecimal Decimal ASCII 1B 63 35 n 27 99 53 n ESC c 5 n Only the lowest bit of n is effective.

EFP9800 ESC/POS Commands Select Head Energizing Time Selects the head energizing time as specified by n. The head energizing time is set for the paper type selected using the Select Print Paper(s) command (1B 63 30). (When both receipt/journal paper and slip are selected, the head energizing mode for slip is enabled.) This command is effective only at the beginning of a line.
EFP9800 ESC/POS Commands • Any printable area that is less than one character wide will be extended to the right enough to print one character. If the area cannot be extended to the right, the left margin will then be reduced. See “ Set Printable Area Width” for more information. Set Fundamental Calculation Pitch Sets the fundamental calculation pitch.
EFP9800 ESC/POS Commands • The width of the printable area is set for the paper that was selected by the Select Paper(s) for Settings command (1B 63 31). • If a fraction is part of the result from calculating the width of the printable area, it is corrected with the remainder being truncated. • If the width of the printable area is less than one character wide (or the equivalent of one character wide for a bit image), the width will be extended to the right enough to print one character.
EFP9800 ESC/POS Commands Define User-Defined Characters Defines user-defined alphanumeric characters for the specified character codes. The character codes may be any between ASCII code 20-7E (95 characters possible). User-defined characters remain in effect until: • A different user-defined character is defined. • The printer is initialized, reset, or turned off. • A downloaded bit image is defined. A user-defined character set and a downloaded bit image cannot be defined simultaneously.
EFP9800 ESC/POS Commands The command is ignored if the value of v, b, f, or h is out of range. Any following data is processed as normal data. Hexadecimal Decimal ASCII 1B 26 v b f [h u1, l1, u2, l2 . . . uh, lh]* 27 38 v b f [h u1, l1, u2, l2 . . . uh, lh]* ESC & v b f [h u1, l1, u2, l2 . . . uh, lh]* *The data in [ ] is repeated f - b + 1 times, once for each character to be defined. Value Range (in decimal) Description v 2 Fixed to 2 b 32 - 126 Beginning character code in range.
EFP9800 ESC/POS Commands The following table describes the format of the character data as expressed by h, u, and l. Value Range (in decimal) Description h 0-10 (7 x 7) 0-6 (5 x 9) Number of u, l pairs (columns) ui ui = 0-255 Data for column i pins. u = the upper 8 pins. Bit 7 of ui corresponds to pin 1, bit 6 of ui corresponds to pin 7, and so on. Bit 0 of ui corresponds to pin 8. The illustration on the following page shows graphically the character data format.
EFP9800 ESC/POS Commands The following example redefines the character 20 (H) for 5 x 9: 1B 21 00 (selects 5 x 9 characters) 1B 26 02 20 20 05 FE 00 10 00 10 00 10 00 FE 00 u1 u5 FE 10 10 10 FE 1 0 0 0 1 1 0 0 0 1 1 0 0 0 1 1 1 1 1 1 1 0 0 0 1 1 0 0 0 1 1 0 0 0 1 0 0 0 0 0 l1 l5 00 00 00 00 00 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 3255 4073– 002 6– 33
EFP9800 ESC/POS Commands The result is the character H as shown in the illustration. In order to define characters for either 7 x 7 or 5 x 9, the character set must be selected by the Select Print Mode(s) command (1B 21). The characters downloaded are stored as the defined character set. Columns are stored in the following order: first received in the leftmost column. Any undefined columns are set to 0. In the example, 5 of 6 possible columns are downloaded with the remainder set to 0.
EFP9800 ESC/POS Commands Cancel User-Defined Characters Cancels the user-defined character designated by character code n of the selected font size. After a particular character is canceled, the corresponding built-in character is printed. The printer ignores this command if a user-defined character is not defined for the character code n or if n is out of range.

EFP9800 ESC/POS Commands Transmit Paper Sensor Status Transmits the status of a paper sensor.
EFP9800 ESC/POS Commands Note: When the Enable/Disable Automatic Status Back (ASB) command is enabled, the status transmitted by ASB and by this command must be distinguished. Transmit Printer ID Transmits the printer’s ID to the host computer. Hexadecimal Decimal ASCII Value of n 1D 49 n 29 73 n GS I n 1-3 The following table shows the printer ID as specified by n.
EFP9800 ESC/POS Commands • The printer transmits only one byte after confirming that the host computer is ready when DTR/DSR protocol is selected. One byte is transmitted without confirming the signal when XON/XOFF protocol is selected. • When the command is buffered, a status is sent causing a possible delay between when the command is received by the host computer and the status sent. This is dependent on the state of the receive buffer.
EFP9800 ESC/POS Commands If any of the status items listed above are selected, ASB is enabled and the printer automatically transmits 4 status bytes whenever the selected status changes. If no status is selected, ASB is disabled. In RS-232C communications, all four status bytes are transmitted without checking DSR. The four bytes must be consecutive, except for XOFF code.
EFP9800 ESC/POS Commands The transmitted status is shown in the following tables: First Byte (printer information) Printer Status Bit Printer Function 0 1 0-1 Not Used Always 0 2 Cash Drawer Connector, Pin 3 Low High 3 Online/Offline State Online Offline 4 Not Used 5 Cover State Closed Closed 6 Paper Feed using Paper Feed Button Not Feeding Feeding 7 Not Used Always 0 Always 1 Second Byte (error information) Error Status 6– 50 Bit Error Type 0 1 0-1 Undefined 2 Mechani

EFP9800 ESC/POS Commands Notes for Bit 1: • The slip paper status becomes 0 (Printable) after paper is loaded and becomes 1 (Not Printable) when the paper is ejected or the printer times out. • When the slip paper is selected and the printer goes into the slip waiting state, bits 5 and 6 of the third byte become 1 (No Paper) and bits 0 and 1 of the fourth byte become 0 (Slip Selected) and 1 (Not Printable) respectively.
EFP9800 ESC/POS Commands Identifying Auto Status Back Bytes Transmitted by the Printer The printer transmits status to the host computer in several ways as shown in the following table: Printer response to a status request from host computer Pattern of status bytes sent by printer Transmit Peripheral Device Status (1B 75) 0**0**** Transmit Paper Sensor Status (1B 76) 0**0**** Transmit Printer ID (1D 49) 0**0**** Transmit Status (1D 72) 0**0**** Real Time Status Transmission 0**1**10 Auto Status
EFP9800 ESC/POS Commands Transmit Status Transmits the status specified by the value of n. In RS-232C communications, when DTR/DSR control is selected, the printer confirms that the host computer is ready to receive data (DSR signal is SPACE) and then transmits only one byte. If the host computer is not ready to receive data (DSR signal is MARK), the printer waits until the host computer is ready. When XON/XOFF control is selected, the printer transmits only 1 byte before checking the DSR signal.
EFP9800 ESC/POS Commands The command is ignored if n is out of range.
EFP9800 ESC/POS Commands n = 3: Slip Status (Transmits the values 00H - 0FH, indicating the remaining printable area) Number of Remaining Dots 6– 56 Slip Status (Hexadecimal) 0-8 00 (Transmitted when there is not enough paper for the next instruction) 9 - 17 01 18 -26 02 : : 117 - 125 0D 126 -134 OE 135 - OF 3255 4073– 002
EFP9800 ESC/POS Commands Real Time Commands The following three situations must be understood when using real time commands. 1. First, the printer performs the real time command upon receiving it and will transmit status regardless of the condition of the DSR signal. 2. Second, the printer transmits status whenever it receives the real time status transmission command sequence, even if that sequence happens to occur within the data of another command, such as graphics data.
EFP9800 ESC/POS Commands To guard against this situation, an application should determine the cause of a busy condition and take appropriate action or pace further real time commands to avoid filling the buffer. There are a minimum of 256 bytes available in the printer’s buffer when it goes busy. The commands are listed numerically by hexadecimal code. Real Time Status Transmission Transmits the printer status in real time.

EFP9800 ESC/POS Commands Do not use this command within the data sequence of another command that consists of two or more bytes. For example, if you send the Set Line Spacing (ASCII code ESC 3 n) to the printer, and a Real Time Request to Printer command (10 05 n) interrupts before n is received, the code 10 for 10 05 n is processed as the value of n for ESC 3 n.
EFP9800 ESC/POS Commands Bar Code Commands These commands format and print bar codes on the receipt station. Select Printing Position of HRI Characters (Receipt Station) Prints HRI characters (Human Readable Interface) above or below the bar code.
EFP9800 ESC/POS Commands Print Bar Code (Receipt Station) Selects the bar code type and prints a bar code for the ASCII characters entered. The command is only valid at the beginning of a line. If the width of the bar code exceeds one line, the excess data is not printed. Illegal data cancels the command.
EFP9800 ESC/POS Commands First Variation: String terminated with NULL Character Hexadecimal Decimal ASCII 1D 6B m [d]n 00 29 107 m [d]n 0 GS k m [d]n NUL 0 = End of command.
EFP9800 ESC/POS Commands Second Variation: Length of Byte Specified at Beginning of String Hexadecimal Decimal ASCII 1D 6B m [d]n 29 107 m [d]n GS k m [d]n m = 65-71, 73 (see the table) d =0-127 (see the table) n = 1-255 (see the table) The value of m selects the bar code system as described in the table. When data is present in the print buffer, the printer processes the data following m as normal data. The variable d indicates the character code to be encoded into the specified bar code system.

EFP9800 ESC/POS Commands Page Mode Overview Page mode is one of two modes which the EFP9800 printer uses to operate. Standard mode is typical of how most printers operate by printing data as it is received and feeding paper as the various paper feed commands are received. Page mode is different in that it processes or prepares the data as a “ page” in memory before it prints it. Think of this as a virtual page. The page can be any area within certain parameters that you define.
EFP9800 ESC/POS Commands Limitations Be aware of the following limitations in page mode: • Bi-directional printing may cause problems and should be avoided. Use Set/Cancel Uni-Directional Printing (1B 55) to set uni-directional printing. • Half dots cannot be used. Page mode requires full dots for 5 x 9 dot font characters (user defined) and bit images.
EFP9800 ESC/POS Commands Command Settings in Both Modes The command settings are treated the same in page mode as they are in standard mode. However, there are some differences: • The settings for the following commands are set independently in both modes: Set Right-Side Character Spacing (1B 20) Spacing (1B 32) Set Line Spacing (1B 33) Printing (1B 55) Set Line Spacing to Default Set/Cancel Uni-Directional • Horizontal tabs are treated somewhat differently in both modes.
EFP9800 ESC/POS Commands The total number of dots for dx is 200 (400 half dots) at 160 half dots per inch. The total number of dots for dy is 704 (1408 half dots) at 144 half dots per inch. • 6– 72 The print starting position for standard height characters is determined by the first line of the page and the direction. Depending on the direction, the print starting position will be in one of the four following positions. See the illustration for a graphic representation.
EFP9800 ESC/POS Commands • A line feed is automatically performed any time the number of characters is greater than the specified width of the page (assuming no commands including a line feed are present). This moves the print starting position to the next line.
EFP9800 ESC/POS Commands Examples of Printing in Page Mode The first example is text on two lines at 9 dots per line with an auto-line feed. The text on the third line is double-high. See the sample printout and the sample code. 1B 4C 1B 57 00 00 00 00 90 01 90 01 “ Page mode text has auto-line feed feature.” 1B 33 2A 0A 1B 21 10 “ Double high” 0C In this example, you enter page mode and select a print area of 400 x 400 halfdots (200 x 200 full dots).
EFP9800 ESC/POS Commands 1B 63 30 04 1B 4C 1B 54 03 1B 44 0C 2D 38 00 09 09 “ OCT 15” 09 “ 96” 0A 0A 0A 09 “ YOUR NAME HERE” 09 09 “ *12.67” 0A 0A 09 “ TWELVE AND 67/100” 0A 0C In this example, begin by selecting slip insertion paper. Then enter page mode and select the print direction to start at the upper right corner and proceed sideways down the page. Set three tab positions at 12, 45, and 56 columns from the left margin.
EFP9800 ESC/POS Commands Flash Memory Commands These commands copy user-defined character sets or logos to the printer’s flash memory. Depending on the command chosen, the object stored in flash memory is then copied to RAM when the printer is powered up, or kept in flash memory for later use. Either way, it is available from the flash memory whenever needed. These commands are only available for the EFP9800 ESC POS emulation.
EFP9800 ESC/POS Commands • If a character set is being copied to flash memory, both the 7x7 and 5x9 versions of the character set are copied. The character set must have at least one user-defined character defined to be copied. • The current state of the user-defined characters is preserved when the command is performed.
EFP9800 ESC/POS Commands Enable Loading the Object When Powering on the Printer Enables the object in flash memory to be copied to RAM when the printer is powered up or the Initialize Printer command (1B 40) is received. This command reverses the previous command, “ Disable Loading the Object to RAM When Powering on the Printer” (1B 7C 01). The command is ignored if nothing has been copied to flash memory.

Section 10 Flash Download Commands These commands are used to load firmware into the printer and to configure the printer. With the exception of the Put the Printer in Flash Download Mode command (1B 5B 7D), these commands are available only when the printer is in download mode. No other commands are available in download mode. Download mode can be entered in one of two ways: • Set the external switches to a special diagnostic setting and power on the printer.
Flash Download Commands List of Flash Download Commands This table lists the commands in numerical order according to their hexadecimal codes. The page number indicates where a complete description of the command can be found in the next section.
Flash Download Commands Flash Download Command Descriptions These commands control downloading of flash memory. The printer returns either ACK or NAK to the host computer when each command is received: • ACK (hexadecimal 06) Sent when the printer has received a host transmission and has completed the request successfully. • NAK (hexadecimal 15) Sent when a request is unsuccessful. The commands are listed in numerical order according to their hexadecimal codes.
Flash Download Commands Request Flash Identifier Returns the size of the flash used. There may be 4, 8, or 16 sectors (64K each) in flash memory. The numbers returned are the number of sectors minus one (3, 7, or 15 respectively). This command assures that the firmware to be downloaded is the appropriate size for flash memory. Hexadecimal Decimal ASCII 1D 01 29 1 GS SOH Select Sector to Download Selects the flash sector for which the next download operation applies.
Flash Download Commands Return Microprocessor CRC Causes the printer to transmit ACK followed by the CRC of the microprocessor: ACK (CRC low, CRC high). Hexadecimal Decimal ASCII 1D 07 29 7 GS BEL Set Emulation Sets the printer to the emulation requested. The command assumes that the printer flash program memory (sectors 0, 1) have been correctly programmed. If these sectors have been erased, the printer returns NAK. The printer returns ACK if the command is performed successfully.
Flash Download Commands Write EEROM Switches Sets the emulation EEROM switches. The command assumes that the printer flash program memory (sectors 0, 1) have been correctly programmed. If these sectors have been erased, the printer returns NAK. The printer returns ACK if the command is performed successfully. Hexadecimal Decimal ASCII 1D 0A d1, d2, d3, d4 29 10 d1, d2, d3, d4 GS LF d1, d2, d3, d4 The first data byte is the settings for switch pack #1, the second for #2 and so on.
Flash Download Commands Read EEROM switches Returns the settings of the EEROM switches. This command is used to verify that the EEROM switches are set correctly. The command assumes that the printer flash program memory (sectors 0, 1) have been correctly programmed. If these sectors have been erased, the printer returns NAK. The printer returns ACK, followed by switch data.
Flash Download Commands Write EEROM Parameter Turns data scope mode on or off, and selects the MICR type (CMC7 or E13B). The command assumes that the printer flash program memory (sectors 0, 1) have been correctly programmed. If these sectors have been erased, the printer returns NAK.
Flash Download Commands Read EEROM Parameter Returns the setting of the requested parameter. The command assumes that the printer flash program memory (sectors 0, 1) have been correctly programmed. If these sectors have been erased, the printer returns NAK. The printer transmits ACK, followed by the value of the request parameter.
Flash Download Commands Erase Selected Sector Erases the sector that was selected previously. The printer transmits ACK if the sector is erased successfully, NAK if no sector was selected previously. Hexadecimal Decimal ASCII 1D 10 nn 29 16 nn GS DLE nn Download Sector Contains a start address (ah*256 + al) and count (ch*256 + cl) of binary bytes to load into the selected sector, followed by that many data bytes. The start address is relative to the start of the sector.
Flash Download Commands Reboot the printer Ends the load process and reboots the printer. Before executing this command, the printer should have firmware loaded, emulation set, EEROM switches set and external switches set to the runtime settings. Application software for downloading should prompt the user to set the external switches and confirm before sending this command.

Section 11 MICR Commands and Parsing These commands control the Magnetic Ink Character Recognition (MICR) check reader, including how it parses the character strings on checks. This section explains these commands. The section that follows, “MICR Parsing,” describes how to create a parsing format and how to create and maintain an exception table.
MICR Commands and Parsing Reread MICR Data Resends the unparsed MICR data (as if the parsing has not been defined) from the previous MICR sequence. Hexadecimal Decimal ASCII 1B 77 52 27 119 80 ESC w P Define Parsing Format, Do Not Save Permanently Defines, but does not save parsing format. See “Parsing Parameter String Options” on the next page. Send this command at the start of day or use in the setup application. If no parameters are selected, parsing is not performed.
MICR Commands and Parsing Parsing Parameter String Options The parsing options apply only to the E13B MICR font only, not to the CMC7 MICR font.
MICR Commands and Parsing Other Parameters Error Number E One Digit Returned 0 Read OK 1 Read error: bad character, empty field invalid length, check digit invalid Status S Field Separator Two Digits Returned 01 No MICR data 09 Mexican check 08 Canadian check 05 Error in transit number 07 Error in account number 04 Error in check serial number 10 Business or commercial check 11 Amount field present 00 No error ’x Field separator preceded by a single quote, so a field separator o
MICR Commands and Parsing Ten parameters are more than enough to specify all variable length fields with a field separator each and other status information that may be helpful to an application. More than 10 parameters are not recommended because they use up space in non-volatile memory (NVRAM) available for the exception table. The parsing parameter string is stored packed in NVRAM starting at word 10, with the total byte length stored in the high order byte of word 10.
MICR Commands and Parsing ESC w p 018 A • Always 18 characters in the account number (high order zero-filled if necessary) • Final Carriage Return ESC w p 018 X A • Always 18 characters in the account number with spaces and dashes removed • Final Carriage Return ESC w p 018 x A • Always 18 characters in the account number with spaces and dashes replaced with 0 • Final Carriage Return ESC w p T 18 X A 04C • All characters in the transit number • All characters in the a

MICR Commands and Parsing Notes All parameters are ASCII characters, i.e. greater than or equal to 0x20, with the exception of a non-ASCII character enclosed in single quotes as a field separator. This applies both to parameter specifications sent from application to printer, and to MICR data returned from printer to application. Parameters are positional; their order in the parameter string is the order in which the parsed MICR data will be returned.
MICR Commands and Parsing Once a parsing format is specified, the following values are returned: MICR Characters ASCII Hexadecimal Numerics 0...9 0x30...0x39 Space 0x20 Dash - 0x2D Field separator* Country code* *As specified in the parsing parameter string With RS-232C communication, the printer adds a final carriage return to the MICR data sent to the application. Check Serial Number Parsing the Check Serial Number Most banks print the check serial number in three easily recognizable spots.
MICR Commands and Parsing Otherwise, a three or more digit number to the right of the rightmost “on us” symbol, and to the left of the leftmost amount symbol if an amount field is present, is the check serial number. txxxxxxxxxt xxxxxxxxo cccc txxxxxxxxxt xxxxxxxxo cccc $xxxxxx$ If both of these searches fail to produce the check serial number, extract the whole account number field from between the rightmost transit symbol and the rightmost “on us” symbol.
MICR Commands and Parsing In this example, without an exception table entry, the firmware would not be able to pick out the check serial number because it is not separated from the rest of the account number: txxxxxxxxxt ccccxxxxxxxxxxo In this example, without an exception table entry, the firmware would not be able to pick out the check serial number correctly, because it is imbedded within the rest of the account number: txxxxxxxxxt xxx-ccc-xxxxxxxxxxo Loading the Exception Table The exception table beg
MICR Commands and Parsing The three high order bits of each byte mark the character type. The characters can be marked in three ways: check serial # character, account # character, or “skip this character or symbol.” The five low order bits of each byte contain the number of characters of that type to extract. Most exceptions will not need to use all six bytes; in that case clear the unused bytes to zero.
