CPC Series
- DMP-1 (Seikosha GP500) more info
- NLQ401 (GLP500) more info
- DMP2000 more info
- Same hardware as DMP3000, but in CPC-style black case (see DMP3000 section for some extra differences)
- DMP2160 more info
- Fast version of DMP2000 (prints 160 CPS, instead of 105 CPS)
PC Series (gray)
- DMP3000 more info
- Same hardware as DMP2000, with following differences:
- PC-style gray case (instead of the darker CPC coloured case)
- More RAM (8Kbyte; instead of 2Kbyte)
- More EPROM (8K+16K, or optionally 32K; instead of 16Kbyte)
- Additional IBM character set (instead plain 7bit Epson/ASCII charset)
- AutoLF signal supported (enabled via J4 jumper; instead of GNDing the AutoLF input)
- User manual addressed to PC users (instead of CPC/MSX/BBC/C64 users)
- and, maybe... additional italics support (DMP2000 doesn't explicitly mention italics support; though probably both DMP2000+3000 do support them)?
- DMP3160 more info
- Fast version of DMP3000 (prints 160 CPS, instead of 105 CPS)

- DMP3250di more info
- Dual-interface version of DMP3160 (with centronics and rs232 ports)
- Like the DMP3160, it prints only 160 CPS (not 250 CPS)
- Slightly redesigned case (bigger transparent plastic lid, and metal stands moved from left/right to front/back side)
- DMP4000 more info

- LQ3500 and LQ3500di more info
- LQ3500di version with dual interface (centronics and rs232)
- Letter Quality 24pin Dot Matrix Printer
- LQ5000di more info
- Letter Quality 24pin Dot Matrix Printer, wide carriage (16 inch paper)
- With dual interface (centronics and rs232)
- LD6000 more info
- Laser Printer (from Amstrad GmbH, for german market only)
- This is a rebadged Sharp printer that emulates an HP Laserjet II
PCW Series (non-centronics)
PCWs were sold bundled with special printers, some with Dot Matrix printers, others with daisy wheel printers. The PCW printers aren't centronics compatible (most of the printer electronics is contained on the PCW computer mainboard, whilst the PCW printer contains only mechanics and low-level electronics).

- 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).

If you do, please also take a photo of the printer PCB.
