I have a laser printer which was working fine. Unfortunately the
computer to which it was attached (which was running Fedora 12) proved
to be sick.
So I've tried moving the printer to two other computers in turn (one
32-bit, one 64-bit) running Fedora 14. I cannot get it to work on either
of them.
I get the message:
lp: driver loaded but no devices found
I tried googling which suggested trying:
alias parport_lowlevel parport_pc
options parport_pc io=0x378,0x278 irq=7,auto
although this was rather an old message. I tried this and got:

The parallel interface may be disabled in BIOS.
