ZX Spectrum and my PCL driver for Deskjets and Laserjets. It was my dream, print text and pictures from ZX Spectrum on some more modern printers, than old matrix printers. Because i had several older HP Inkjets with LPT port and because PCL language is documented, then i created simple interface and wrote two software drivers. One driver is for Desktop (in ZX Spectrum world is program Desktop something like Office for PC's) and second for Sinclair BASIC. More about this at my website cygnus.speccy.cz, but for now only in Czech.
