Codes 80h..9Fh and FFh act as mirror of control codes 00h..1Fh and 7Fh
Codes 20h..7Eh are ASCII characters (some changed in "international" modes)
Codes A0h..FEh are italic versions of 20h..7Eh
Some one-digit parameters (like on/off flags) may be recognized both is binary chr(0xh) as well as ASCII chr(3xh).
The DMP2000 (and up) supports all Epson FX80 control codes, plus some additional ones:
- ESC SO and ESC SI (mirrors of SO and SI) (for some reason, these mirrors are often supported by Epson-clones like Star LC10, though they are rarely found in official Epson specs)
- ESC "x" n (select NLQ/Draft mode) (the original Epson FX80 didn't support NLQ, however, the ESC x command is found in other Epson models like LX80 and FX86e)
- ESC "m" n (select IBM charset) (this seems the be an Amstrad invention, supported only by DMP3000/3160, not supported by DMP2000/2160, nor by real Epson printers, nor by Epson-clones like Star LC10).
