I have recently set up my wireless network at home, and set up a new printer to become the default network printer, although when I try to print from my iMac to the (network) printer hooked up to the Dell, the page is fed and is produced to the tray, but it doesn't actually print anything on the page. The ink is full, and prints perfectly with the Dell and another PC laptop, but when I try to print something it just comes out blank. Anyone know anything about this?
