Hi guys, I have been on the phone to HP for days they are blaming my computer but really it doesn't sound right... Brand new iMac, and a brand new CM1312... I have plugged it directly into the back of the computer via the USB the computer sees it and there is no problem with printing... BUT using the HP Scanner software it cannot see the printer via USB... I used the HP Set Up Wizard and when it comes to the screen asking to find the USB or Network printer it can't see it under USB, EVEN THOUGH IT PRINTS VIA USB... Has anyone had this issue before? Am I better off using an ethernet cord?
