That is done with the cleaning with forethought, you can see at Canon. While I can clean the printer head of the black ink separately, which then protects the color inks. The 4 color inks but I can only be cleaned together. With a consumption of 25% of the content per cartridge is that then every 15 cost per cleaning for a picture. As is to put an end to this rip-off for urgent action in Brussels.
I can only advise you to procure scarce 2-300 a laser color printer, thus printing 2-4 years without maintenance. Photos on matte paper are very good. To order high-gloss photos online then best. Just takes a few days, but should save 90% of costs.
