[quote name='Revenantae']Depends on what Canon model you have. If yours is the type where the ink cartridges are JUST ink containers (no integral print heads etc.) then they are trivial to refill, and that will make them much cheaper than ANY manufacturer's carts. I've been refilling a PIXMA series for about 3 years, thousands of prints and hundreds of photos on a single refill kit I bought for about $50. I still have about 1/3 of the ink remaining and the prints have been just as good as with official Canon carts.
Also note that lasers are the kings of cost/print. However, even expensive color lasers can't produce photo output that is as good as a cheap color laser. My $200 Canon inkjet absolutely nukes my $1500 Konica color laser for photo quality. However, for things that don't need to look top notch, the Konica costs about 5 cents per color page.[/QUOTE]
I used to screw around with the refill kits and knock-off cartridges, but after a while, the printer heads got messed up and it wouldn't print yellow or red... everything came out black and blue... it made for some interesting prints. (no, running the print-head cleaner did not work)
