Parallel port printer problems

[Nathan Weston <nweston@hamilton.edu>]

I have a parallel port printer that used to work just fine... however, I 
recently reinstalled after a drive failure, and now it's not working. I have 
parallel port support in the kernel. At boot-time, I get the messages:

parport0: PC-style at 0x378 [PCSPP,TRISTATE]
parport0: cpp_daisy: aa5500ff(98)
parport0: assign_addrs: aa5500ff(98)
parport0: Printer, Canon BJC-1000

However, printing through lpr doesn't work, and "cat file > /dev/lp0" gives me
bash: /dev/lp0: No such device

Same thing with lp[12] and par[0..2]. My printer used to be /dev/lp0... now 
it doesn't seem to exist at all.
Any suggestions?

Thanks,
Nathan
