I have an Epson Stylus Photo 960 printer hooked up to my PC which is hooked to my wireless/ethernet network. I installed the printer on my mac wirelessly but there is a problem when I print. The printer prints the black ink very, very lightly or doesn't even print it at all. I'm sure the black ink cartridge is not empty because when I print from the PC it prints black ink fine. And it's not a network problem because when I print from other PCs on the network to the printer it prints fine. So there must be a setting somewhere on my Mac to make it to this. I used to have the mac directly connected to the printer and it used to work fine but then I started having this problem, so I must of accidently changed something. Any suggestions? Thanks.
