My iMac has printed on all my printers - Epson, Canon, HP - with a washed out faded look. It has always done this since new whether printing from Acrobat, Photoshop or any other program. From looking at internet posts this is a common issue and there must be a setting somewhere in my iMac to correct this problem. Currently I have to transfer everything to my PC to get decent printing. I'm not too much of a techie, so a simple solution would be wonderful. Any ideas?
