I never really thought about that, but that sure is a clever idea.

I have an R200, and its CD printing is nothing short of phenomenal.

I'm not really familiar with Epson's inkjet printers, since this is my
first non-HP inkjet, so would using a different kind of ink (or the
solvent you mentioned) cause any other parts to be damaged?  The ink
in Sharpie pens would be perfect---it dries very fast on copper, and
resists etchant VERY well.

It's not a bad idea if it could work!  And the R220 (the R200's
replacement) is cheap enough that I'd buy one just for PCB printing.
