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 code function (where applicable):
ASCII Code The standard ASCII name for the control code.
Hex Code
Dec Code
Purpose
Comment
Example
† ("dagger")This symbol means the code produces non-Epson behavior in
IMPORTANT
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 n)
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
158
The control code numeric equivalent in hexadecimal.
The control code numeric equivalent in decimal.
The function(s) of the control code.
Any exceptions or limitations to use of the control code.
Where applicable, we present a sample using the control code,
along with the result of running the program.
