I'll start by saying that I don't like Epson. Their printers make the
best quality photos for the low price, the printhead technology is
different than HP or Canon and allows for better prints, but the rest
of the hardware in the printer is junk. I bought an R340 and only had
it for 3 months before it broke down, the CD printing function failed
first, then the rest of the printing functions slowly broke. Their
warranty service is terrible, it's not an 800 number, and they hassle
you every step of the way to get it fixed, the staff is rude, and
they charge your credit card (they said it was just a hold, but then
they tried to charge it) before they send you a replacement. So if you
buy an Epson, expect a very big fight if you have to claim warranty
service and don't give them your debit-with-credit-ability card
number, only give them a 'real' credit card if you /have/ to.
I know for a fact that the R340/320/300M/300/220/200 ink (all the
same) will not work on copper or brass. Since I use paper thin sheets
for what I do, I could feed it through the normal paper path and it
would print on it, but then bead up. The higher end pigment printers,
such as the R800, R1800, and R2400 use Ultrachrome inks which are slow
drying, and only designed to work best on special art print papers,
and not 'standard' inkjet papers which is why they don't work on
transparencies and can smear if not allowed to dry for quite awhile.
However, the Epson C-series printers take Durabrite ink, which have
something similar to an acrylic enamel in it, which dries nearly
instantly, and is waterproof. It dries so fast that the C-series
printers have an extremely long history of breaking down nearly
instantly - if you do not print constantly, at least 1x a day, and
preferably much more, the ink will dry in the print heads and destroy
the printer. The C-series printers do not have a CD printing slot.
However, the printheads in the R-series and C-series printers are very
similar (there are aftermarket pigment inks for people who want to use
Ultrachrome-quality ink in the cheaper R printers). The cartridges are
also exactly the same size and shape.
My suggestion would be to go to Epson's website and get a refurbished
R200 printer, which runs around $60-70, less than a set of the ink
would cost. Order a black Durabrite cartridge with it, or pick one up
from the store (the newest Durabrite Ultra type cartridges have the
Chair logo on them), swap the chips with the black cartridge that the
printer came with, and try using it that way. Make /sure/ that you
print at least a little black every day after doing this, or the
printer /will/ clog up. I wouldn't be able to tell you how to modify
the CD tray to accept PCBs.
I have seen 'Sublimation' aftermarket refill kits (not the same as a
real dye-sub printer) for Epsons which allow you to create prints that
can be transferred to mugs, and I have seen one webpage that also
mentioned printing on 'specially treated foil paper'. I cannot find
this website right now, though.
