The Epson 200 that came with my Nikon D50, which I returned in order to get
another AIO, did have a CD print tray, which I thought was a pretty nice
bonus.
I liked the r200 in the fact that the color rendering was superb, and
looked good on all media types. The canon... well doesn't but in my
experence is less prone to clog. CD printing on the canon seems to
work best if you up the intensity dial on your print driver to dark and
+10 or +15. Aside from this mild annoyance it does a good job, esp
with black text, though the epson I found to be better for white text
on a color background. The r200 is geared to self distruct... as in
it's diper becomes too full and refuses to print after a relativly
short period of time... and not only can't be replaced by the end user
but according to someone in this group part of the printer's case is so
fragile that it has to be destroyed to replace the diaper. The canon
also has a diaper, but does not fill up nearly so quickly as the epson,
the volume of waste in is less, not as little as HP. It can be
repalced, not by your average end user but it is possible without
destroying the printer. There is a work around for the r200 to route
ink elsewhere. The only other benifit to the r200 was that you could
get away with using non-printable discs in the printer so long as you
were willing to wait a week, a month, or however long for the ink to
dry. It's not beautiful but legible. Canon isn't legible at all on
non-printable media... in fact the ink beads up and rolls off the disk.
The Canon CD printing software is nothing at all to write home about,
in fact it's rather horrid. Epsons is only slightly better. But
that's software, and software can be replaced. Surething doesn't
directly support the canon cd printing but there is a template you can
ask for from support. I'm sure there are other options, but I'm not
aware of them.
The tray is costly... parts now had the cheapest price for under
$10ish... about $12/$14 shipped.
But needless to say each printer has it's benifits... at least with
software you can if worse comes to worse get it selsewhere. CD
printing on the other hand you can only get in Epson's stand alone
units and Canon indluing their AIOs.
There are new AIOs from canon, but none with a faxmodem onboard or a
sheet feeder. The new ones offer higher resolution and take new ink.
I know nothing about CD printing on them, only the
ip3000/4000/5000/6000/8500/mp750/760/780.
