Appendix A
SQ-2000 Command Summary
This appendix gives a brief summary of the SQ-2000 com-
mands (control codes). While this is a complete list of the com-
mands, the descriptions are not complete in all cases. The com-
plete descriptions of all the commands, including examples of
their use, can be found in the
LQ-2500 Programmer’s Manual
also
available from your Epson dealer.
In some cases the explanations given here describe the appa-
rent function of the commands, rather than the actual mechanical
movements of the printer. For example, since the printer prints in
both directions, the line feed command may not actually return
the print head to the left margin if the next line prints from right
to left, but the final effect on the printed page is the same as if it
had.
The commands are organized into five logical groups: Vertical
Spacing Commands, Horizontal Spacing Commands, Character
Set Commands, Graphics Set Commands, and Miscellaneous
Commands. The function is what the printer will do when given
the proper command. The format is the correct syntax for the
ASCII code that the printer understands. This code may be ex-
pressed as a symbol, a decimal value, or a hexadecimal value
depending on the program you are using. Where n (or another
italic letter) is used as a variable, it stands for a numerical value.
