i have recently switched from pc to mac, and have been frustrated with the printer set up. i have an hp psc 950 (all-in-one) , and it does not seem to work. i have downloaded and installed the updated drivers, checked all connections, etc. there still seems to be a communication error. can someone please help? i do not have the cash to buy a new printer, i will have to return this imac and return to the pc world.
