Chapter 4 Configuring the Epson FX-1050 Emulation with Control Codes

Configuring the Epson FX-1050 Emulation with Control

Codes

The remainder of this chapter describes the Epson printer control language

codes that may be sent from a host computer attached to the printer, in order

to invoke and configure numerous Epson emulation functions.

Format for Control Code Descriptions

The following information is listed for each control code (where applicable):

Name The title or function of the command.

ASCII Code The ASCII mnemonic for the command is shown. Command

sequences are in 7-bit (ASCII) form.

Hex Code The code or command sequence in hexadecimal numbers.

Dec Code The code or command sequence in decimal numbers.

Purpose The function(s) of the control code.

Discussion A discussion of the uses of the code or command sequence,

including a description of exceptions or limitations to normal use.

Example A sample is provided when it is possible to illustrate the effect of

a control code or if a specific syntax is required.

†

(“dagger”) This symbol means the code produces non-Epson behavior in

your printer.

NOTE: If you specify any parameters for a control code other than the ones

that are defined in the control code description, unpredictable results

may occur.

Escape Sequences

An Epson control code consisting of more than one character is called an

escape sequence because the first character in the sequence is always the

ASCII ESCape character. ESC alerts the printer that a special function

command (not printable characters) follows.

The format for an Epson escape sequence is:

(ESC)(parameter 1)(parameter 2)...(parameter

)

For example, to select emphasized (offset) print, send the ESC character

immediately followed by the E character (do not add a space character):

ASCII: ESC E Hex: 1B 45
