Has anyone had printing difficulties with a G3 Minitower? One time it prints just find, the next time I get a message that it cannot locate my printer. There are three of us in our office having the same problem...but we are not linked and do not share software. Things we have tried include...different printers, different printer cables, reloading software and even a new logic board in the computer. The problem continues no matter what we try. Replacing the logic board was the suggestion of an Apple representative who came to the office, so we have had good advice...but still have the problem. Any suggetions would be greatly appreciated.
