I have two 6500/250's connected to an Epson Stylus Pro Printer. I ordered and installed the optional localtalk interface card. The problem is that the ppc's print fine when connected through the serial port, but a problem arisses when i connect them through the card. I get a message saying that the printer is busy and waiting for another user's job to print. This happens even if there is no other computer attached to the network. I have cleared the spoolers, reinstalled the drivers,ordered and installed a new card, programmed the printer options, and I still can not find the problem. Any ideas?
