Did printing work before you "re-adjusted" CUPS? Try using the USB
and parallel connections to print. Is there a significant difference?
Get yourself a few small PostScript files from different sources.
pdf2ps and Firefox are two ways to produce one. Plug the printer
into a USB port and check the device in /dev/usb (lp0, lp1?). Send a
file directly to the printer with
cat <PS_file> > /dev/usb/lp0
How does that go?
