The CPC [[Printer Port]] has only 7 bit data. Which is sufficient for english English 7 bit ASCII character sets, but not enough for 8 bit character sets. Also, printing bitmap graphics usually requires 8 bit data (though usually can also print 7 pixels columns combined with a reduced line-feed rate). Amstrad's DMP1 works perfectly with 7 bit, but Amstrad's later DMP2000/DMP2160 include a few functions that won't work on 7 bit ports - so even the official CPC printers aren't fully compatible with the CPC printer port. There's a software solution though, proposed by [[Amstrad Computer User]] using a replacement driver (only for printers accepting EPSON control codes).
== Internal 8 bit Printer Ports/Mods ==
* Centronics to serial 8-pin DIN Adaptor for "Gabriele 9009" daisy-wheel printer from Triumph-Adler (DIY, [[CPC Schneider International]] 12-1985, pages 88, 89)
* KDS Printer T Switch ([[KDS]]) - allows to connect 2 printers, the desired printer can be selected via software
== Software solution (only for printers that support EPSON control codes) ==
