I got the rules setup in devfs.rules, no problem. When I turn on the
printer it's detected...

crw-rw  1 root  cups0,  88 Apr 22 21:20 /dev/ulpt0

according to /var/log/cups/error_log it prints...

IIRC, you should be able to actually write

echo "something" >> /dev/ulpt0

and it should print? Might be useful for testing and stuff.

Test goes to the same black hole. I think I've found the problem...

uhci0:  port 
0xb400-0xb41f irq 3 at device 31.2 on pci0


Perhaps putting a USB 2.0 controller in this old machine might make a 
difference. :)


Anyway, after a quick bit of googling around for your problem (I've 
had CUPS problems many times in the past myself and I know how hard it 
can be) I found this:


Here is a workaround:

In printers.conf () you will probably find a line like this:

DeviceURI usb:/dev/ulpt0

change usb: to file:, so that it looks something like this:


DeviceURI file:/dev/ulpt0

Then restart cups. Cups will not read any status information from the
printer, but at least it can print. Be warned about unknown side effects. :)

Have a look at the cups logfiles in /var/log/cups. They should give you
some pointers. You'll probably need to set the device permissions for
ulpt in devfs.rules, not devfs.conf!

Thanks for the info. This didn't actually fix the problem, but I know it 
was needed since I read somewhere that everything that cupsd spawns 
runs as cups.

What I ended up doing was resetting my cupsd.conf to default and redid 
my settings. I must have had a typo in there somewhere before because 
as soon as I restarted cupsd after making the changes, the parallel and 
usb ports suddenly became available as devices for the printer. I had 
previously selected lpd and then manually specified the uri as 
parallel:/dev/lpt0.

The laser on the parallel port is now working fine. I also went ahead 
and setup my deskjet on usb:/dev/ulpt0. Print test pages get marked as 
completed but nothing actually comes out of the printer. Still trying 
to figure that one out.

IICR, the print device should belong to the cups group. At least, that's
my working setup. 

I have the following in /etc/devfs.conf:

# Give cups printer access
own lpt0root:cups
permlpt00660

If you don't want to reboot;
# chown root:cups /dev/lpt0
# chmod 0660 /dev/lpt0

Trying to print a test page from the cups web interface on a client

change anything.

Can somebody tell me what I've done wrong or point me in the direction I
