The Canon Pixma MP830 is an all-in-one (i.e., printer, fax, photocopy)
with auto-duplex.
It works fine for me.
It uses five cartridges simultaneously: one PGI-5BK for B&W, and CLI-8
black/cyan/magenta/yellow. Damndest thing is that even when the
machine is commanded to printed only black ink with shades of grey, it
will persist in using tiny amounts of the color ink anyway. And,
although Canon says you can command the machine to continue printing
B&W after a color cart is exhausted, somehow what should be black
print is tinted some peculiar concoction of the remaining colors.
This is extremely annoying and means that you must always have a
fallback supply of all the cartridges.
Fortunately, refurbished and third party cartridge are readily
available through internet dealers (Amazon is a good source). Canon
pretty much prevented user-refilling by building the cartridges so
they depended on a vacuum effect that is ruined by attempting to
reload with a hypodermic, and also with a microchip in each cartridge
that rachets down to tell the machine how much ink is left in the
cartridge (but worked only downward and didn't report any sort of
refill). Until last year this was sufficient to make third party
carts unreliable, but evidently in the last year at least several of
the third party suppliers have mastered both vacuum system and the
microchip gimmick, and I have found recent third party carts to be
very satisfactory.
