The prints look good.
Did you restart/repower the printer, before trying to print?
What document format is being used on /dev/ulpt? Maybe you have to use anot=
her=20
format. Did you use the correct PPD file for your printer? I have a brother=
=20
printer here which uses USB, and claims to support PCL 6, but whenever I pr=
int=20
something in PCL 6, it's not recognized. I found out I had to download a=20
special PPD file, and install foomatic-rip, for cups. Then it worked using =
the=20
GDI protocol.
