DMP1 Control Codes
| Hex | Decimal | ASCII | Type | Description |
| 0A | 10 | LF | Misc | CR+LF |
| 0D | 13 | CR | Misc | CR or CR+LF (selectable via DIP-switch) |
| 0E | 14 | SO | Width | Double Width Mode (also restores 1/6" line feed rate; after graphics printing) |
| 0F | 15 | SI | Width | Normal Width Mode (also restores 1/6" line feed rate; after graphics printing) |
| 10,hi,lo | 16,hi,lo | DLE "NN" | Misc | Print Position in character units (NN = two-digit ASCII, "00..79") |
| 14 | 20 | DC4 | Misc | CR |
| 1B,10,hi,lo | 27,16,hi,lo | ESC DLE hi lo | Misc | Print Position in dot units (hi:lo = 9bit binary, 0..479) (lo=lower 7bit, hi=upper 2bit) |
| 1B,4B,hi,lo,gfx0,gfx1,.. | 27,75,hi,lo,gfx0,gfx1,.. | ESC "K" ... | Graphics | Graphics Mode (hi:lo = 9bit count, 0..479) (lo=lower 7bit, hi=upper 2bit) (followed by as many bytes, with bit0=upper pixel .. bit6=lower pixel). This command additionally changes the line feed rate to 1/9 inch; the new rate is kept applied for text and graphics (until canceled by chr 0Eh/0Fh). |

NLQ401 Control Codes
The NLQ401 supports a fraction of the Epson control code set, plus some NLQ401-specific, non-Epson codes. The missing Epson codes include both newer codes, as well as older ones (like custom TAB channels, which are supported even by very old Epsons from 1981).
Caution: The NLQ401 firmware strips Bit7 of all incoming characters, so one is restricted to use 7bit codes, even if one does own an 8bit Printer Port. Accordingly, only 7-pin graphics can be used, and some numeric parameters cannot be set to values with bit7=1.

- 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).
