APPENDIX C. EPSON LQ AND FX EMULATION MODES
LQ AND FX EMULATION COMMAND SUMMARY
This section lists the control codes and ESC codes supported in the LQ and FX emula - tion modes. Some LQ and FX printer codes are not available, either because the func - tions are not required (such as draft printing) or are not possible because of the different technologies used in these printers.
To use the commands explained in this section, you have to make batch files and data files. Normally, only experienced users attempt to use these codes. However, you can get a rough idea about how to make batch and data files by looking at page 18 and the pages following that. Also, you will probably have to consult Epson manuals and other software development materials to get the most out of these commands.
The following commands are either not available or are ignored in LQ or FX emulation mode:
ESC < | Unidirectional mode (one line) |
ESC 8 | Disable paper end detector |
ESC 9 | Enable paper end detector |
ESC U | Select print direction |
ESC s | Set/cancel |
ESC r | Select color printing |
ESC i | Incremental view |
The following commands are available in FX mode but not in LQ mode:
ESC 1
ESC ^ Select
ESC I Select character code table
The printer commands listed below function in a slightly different way when used in LQ or FX emulation mode. Also, many of the commands that control the print position use approximations because of the difference in print density between the LQ and FX print - ers.
ESC G/ESC E
These commands produce identical bolding effects on your printer. On an actual LQ se - ries printer, these two commands create slightly different effects and can be combined to produce darker characters.
SI/ESC SI
These commands print 10 cpi characters in a 16.66 cpi font, and 12 cpi characters in a 20 cpi font. On an actual LQ/FX series printer, these commands condense the font.
ESC x
This command is normally used to select between draft and LQ quality with an LQ or FX printer. However, this command has no effect on your printer’s print quality since all characters are printed at 300 dpi (dots per inch).
