Hello, all, My iMac is running 10.6.8 and has worked for two years with an HP 3030. I just bought an HP m1212 yesterday, but the printer will not read the USB port from the Mac. I installed the printer on a Dell laptop and it prints fine via USB with the same cord. I've already tried to reset PRAM and SMC. 1. Is there any common way to make USB ports work again? (They work with some peripherals, not with others.) 2. Could I connect the printer by the ethernet ports? Thanks a million.
