No devfs device node for printer

I installed CUPS and configured my HP DeskJet 842c at the command line:

I'm having the same trouble with my system (Abit KG-7 mobo, Athlon T-bird), and I also tried running

mknod /dev/lp0 c 6 0

to create the fs node, without success. Are the maj/min device numbers in the command correct?

I was on the right track. To fix this problem:

Run

mknod /dev/lpX c 6 X

where X is the number of the parport you want to use (usually 0). If you have parallel support built as a module, modprobe it in. Finally, configure CUPS as before for your printer.

I just tried what you suggested and still cannot get CUPS to open the device URI. I tried adding /dev/lp0 and configuring CUPS to print there, and alsa adding /dev/lp1 and configuring CUPS for that. Neither worked. I do now have lp0 and lp1 in my /dev/ directory. I compiled support for parallel ports, PC-style hardware, and IEEE1284 transfer modes (ECC/ECP) directly into the kernel. Any ideas?

Hmm.../dev/lp1 should not work unless you actually have a second parallel port; if you only have one, it's /dev/lp0. You can check if the parport routines are functioning by running

dmesg | less

and looking for two lines like the following:

parport0: PC-style at 0x378 [PCSPP,EPP]
parport0: Printer, <name of printer>

Other than that, I'm low on ideas right now, but I can give you a blow-by-blow of what I did.

1. Built kernel during install with parport routines modularized.
2. Emerged CUPS after install.
3. Tried to add printer and received error message.
4. Removed printer configuration (even if it can't find a port, lpadmin still writes a printer configuration in the CUPS files)
5. Ran mknod to create /dev/lp0.
6. Rebuilt kernel with parport routines internal.
7. Rebooted.
8. Successfully added printer configuration.

HTH.

For me and my HP Deskjet 400, the problem ended up being that I needed to NOT compile in IEEE 1284. Now my hardware is a lot different from yours but this might point you in the right direction...

Good luck!

This should fix the problem.....

"Then go to Character devices and enable Parallel Printer Support."

Wow tubs!

Way to dig out an old topic! It's been 2 years since the original post! That's gotta be some sort of record!

LOL - just messing with you of course :twisted:
