The elves have been working hard, and microM8 now has Epson colour printer support just in time for Christmas.
Using colour Print Shop (available in /appleii/disk images/applications/print shop) you can print colour cards, posters and more.
When you print, the output ends up in your /(home directory)/microM8/MyPrints folder in PDF format.
The printer settings are: 4-colour / 3-colour / Monochrome Epson MX via a Parallel card in slot 1.
Your existing copy of microM8 should automatically update with the printer support, otherwise you can download it from here.
