This is just the thing I needed 30 years ago :-(
To be less facetious though, this seems like a nice project (*), but I print so much less these days than in the past. I printed a lot of color stuff when I was in school; but these days I just settle for black/halftoning from a laser printer, for when I actually need something printed, and color on screen only.
