Got a real problem here. I've got my computer and 2 Canon i9900 printers which I am using for a small business doing digital phtography with my Canon D20 digital camera. My problem is I take the pictures and load them into my computer and they look great but when I print them, they are not good at all. One printer tends to print a very "blueish" picture and the other prints a ver "redish" one. The ink seems to pool at the bottom of the printer head as well. I've tried changing the type of paper I'm using as well as cleaning the head and replacing the ink but the problem still comes back after printing 5-10 photos. Can someone help with how to fix this or do i have to calibrate my screen and printer so what I see on the monitor is what I'm printing on paper? I'd really appreciate any help at all.
