Please help solve printing weirdness

[Kieren Diment <kieren@diment.org>]

For some reason I am having printing weirdness on this machine.  I am
running testing, upgraded from Woody if that helps.  I have recompiled
my kernel to contain parport and parport_pc  (Kernel 2.4.18)

I have a HPLJ2100 printer.  I have lpd  and  magicfilter installed: 
magicfilter.conf looks like this.  I get the following errors:

kd:~$ cat /var/tmp/test > /dev/lp0 
-bash: /dev/lp0: Permission denied
kd:~$ su
Password: 
arthur:/home/kd# cat /var/tmp/test > /dev/lp0 
bash: /dev/lp0: No such device

	:if=/etc/magicfilter/hpijs-filter:\
	:af=/var/log/lp-acct:lf=/var/log/lp-errs:


 ls -l /dev/lp? gives:
crw-rw----    1 root     lp         6,   0 Mar 15  2002 /dev/lp0
crw-rw----    1 root     lp         6,   1 Mar 15  2002 /dev/lp1
crw-rw----    1 root     lp         6,   2 Mar 15  2002 /dev/lp2

Can anyone tell me what's wrong?
