Back at my home office, I have a newer PC running 9.10 (10.04 now, since 5/14). Add Printer shows lpt #1 and all the serial ports. /dev/lp0 is present.
Is the bios on my old PC too old so Ubuntu > 8.04 can't detect parallel ports properly? I see a warning about the bios too old scroll by at startup.

I too, have parport running.
I was able to add it just fine under 9.10, so for me it's something that has changed since that release. I don't have 9.10 installed anymore as I did a clean install of 10.04 RC.Code:chui@matrix:~$ lsmod|grep parport parport_pc 25962 1 parport 32635 3 ppdev,parport_pc,lp
I'm running it on a Thinkpad T42. It's the only computer I have around that still has a parallel port, unfortunately. I do see it when i sudo, though :
Code:chui@matrix:~$ sudo ls -l /dev/lp* crw-rw---- 1 root lp 6, 0 2010-04-26 01:01 /dev/lp0
If parport and parport_pc are running, I can't be of any more help because I don't have a clue why you don't see /dev/lp0. I just upgraded my computer to a new motherboard and I now no longer have a parallel port, and this is the only machine I have that is running 10.04 so I can't experiment and see if I can figure it out. I hope someone more knowledgeable jumps in.
At my home office, I tried booting my newer PC on a 10.04 iso CD just now, and lp0 was there. Didn't need to sudo to list it. And Printers>New showed LPT #1.
Must be that my old PC is just too old to run unbuntu > 8.04. I got it back in late 99 right after my house fire. I tried to install XP on it and it ran too slow for XP. Ubuntu gave it new life and extended its usefulness. I can easily roll back to 8.04 on that old girl and be able to print again. What added features will I miss between 8.04 and 10.04?
Is there a linux way to get a report on what bios this old girl is running? biosdecode?

I've had similar issues ... with printers vanishing. Try this:
0) un-plug **vanished** printer from computer
1) turn off both computer and printer.
2) re-plug printer. turn on printer
3) turn on & boot computer
4) ,,, mebby the printer now re.appears when you reference the printer config dialog. Or mebby it just automagically appears & works .
Nss0000 - Sounds like a long shot since I don't know how a system restart will make /dev/lpt0 reappear, but I'll give it a try next time I'm in that office.

Yeah, Ns000, that didn't work. Any other ideas? I'm rolling back to 8.04.

Clutch the pearls! >>There's a bug reported on this https://bugs.edge.launchpad.net/ubun...ux/+bug/369850
I'll have to try the fix next time I'm at the location.

The fix worked.
First I reinstalled 10.04.
Just type in sudo modrobe parport_pc
Then Add printer showed not only the parallel port but found my HP 985C. Installed the driver, and started printing test pages.
Not sure yet if adding the modprobe line to /etc/modules makes the printer work after reboot.
