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:

Feb  5 16:14:17 susannah kernel: [  582.886574] parport 0x378 (WARNING): CTR: wrote 0x0c, read 0xff
Feb  5 16:14:17 susannah kernel: [  582.886579] parport 0x378 (WARNING): DATA: wrote 0xaa, read 0xff

Feb  5 16:14:17 susannah kernel: [  582.967157] parport1: PC-style at 0x278, irq 0 [PCSPP,TRISTATE]
Feb  5 16:14:17 susannah kernel: [  582.967172] IRQ handler type mismatch for IRQ 0

Now CUPS seems to think the pronter is online, but nothing prints anyway
(not surprising in the light of those messages above). (I only actually
have one parallel port, but I couldn;t remember which address
corresponds to lp0).

Any suggestions?
