• Character codes 00h-FFh...
  • Codes 00h..1Fh and 7Fh contain control codes, but at least some of them can be also used as print-able characters; at least when enabled via ESC "I1" (according DMP2000 manual chap6/page7 example: chr(6) is a print-able (user defined) character. others like chr(27) are obviously not printable)
  • Codes 20h..7Eh are ASCII characters (some changed in "international" modes)
  • Codes 80h..9Fh and FFh act as mirror of control codes 00h..1Fh and 7Fh (this mirroring can be disabled via ESC "6")
  • Codes A0h..FEh are italic versions of 20h..7Eh
• 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).
• Some one-digit parameters (like on/off flags) may be recognized both is binary chr(0xh) as well as ASCII chr(3xh).
