Tony, here's a quote on this problem that is likely pretty accurate regarding what you're experiencing. I saved it, from MacFixIt I believe, way back when I had the same problem, so I'll just paste it in... here... "This is likely caused by AppleTalk. AppleTalk tends to take over the printer port when active, and this will prevent a serial printer from using it. This prevention makes the serial printer's driver choose the modem port to print to. The act of making AppleTalk inactive (either in the chooser or the AppleTalk control panel) is not sufficient, since the resources loaded at startup. The best way to make sure it stays off is to make it inactive, then immediately shutdown. When you start back up, check the Chooser to make sure it stayed off. However, be aware that using file sharing or Apple Remote Access will make AppleTalk active again. In this case, a better workaround is to make sure the Apple Remote Access Client is installed, this grants a new option in the AppleTalk control panel. This new option is called "Remote Only", and choosing it will then route AppleTalk to that, freeing up your printer port for use by your serial printer."
