I have never seen an apple system but the symptoms you desribe sound like you are plugging a serial printer into a parralel port or your printer port on the PC is bad. Modems are usually serial devices and printers are parralel devices on non apple PCs.

First, try dragging the finder preferences to the trash and restarting.

If this doesn't work, reinstall the printer software and restart.

If that doesn't work, do a clean reinstall of the system software.
