I've been trying to help a friend with an early iMac. The computer has a an Epson 740 inkjet printer attached. The problem is that when you call up the printer in the chooser I get a message that says that the printer port is busy with another application. This is not the case. I've reloaded the printer software to no avail. Any ideas?
