Jim Hood and I got an HP Color Inkjet 500C when they first came out. It had a Centronics parallel interface, and an Epson cartridge. That allowed some fooling around, but not a lot of graphics. So, we hacked TIF images from Jim's ST into three files, one of each color. We could then print each color, one at a time, backing up to the starting point after each pass. The end result was really good, considering.
1200XLs ruled...
Anyway. Get yourself a 500C to play with!
