Printing Errors -193 and -48

[dvalley]

We have a cursed iMac here at work which continuously has problems (user error: replace user and continue). This time it has me stumped. Only in FileMaker (at first 6 Unlimited under OS 9.1) it would not print, giving those two error codes. I replaced the OS (to OS 9.2.2) and FileMaker (to Developer 6). It still gives the errors when printing. Other applications print fine. Any ideas?
