On the video link at the end of this page, the set up I am running the Artist II in is a ZX Spectrum Next KS1 in Spectrum 48k personality with Kempston Mouse and Multiface 1 options available. Plugged in to the Next's expansion port is an LPRINT III Centronics interface (actually a modern clone because my old original one broke), which in turn has a RetroPrinter centronics convertor connected to it. An Interface 1 and a ZX Pico MD are attached too to provide the equivalent of microdrive storage using .mdr images with also the ability to load .z80 snapshots (and TAPs) all from on an SD Card. A digital voice recorder provides the equivalent of tape LOAD and tape SAVE functionality.
The LPRINT III interface adds a Centronics output to the Next. This is connected via a standard centronics printer cable to the RetroPrinter. The RetroPrinter converts the printing commands from Spectrum applications intended for a 1980s Epson FX 80 Dot matrix printer and sends them via Wi-Fi to my (fairly) modern HP Envy 5546 printer, with the printout looking as it would have on an 1980s Epson FX dot matrix printer. Importantly, for Wordprocessors the RetorPrinter conversion includes retaining all the originally intended print styles e.g. bold, underline, italic, superscript, subscript, and proportional. Alternative font options are also available. I will show these working in a subsequent video using "The Writer" WP program for the Spectrum with this same set up. In the case of the Artist II shown here the RetroPrinter is simply converting the COPY command.
