[Bug 37881] Parallel port printer not working

[grendel970]

Public bug reported:

Affects: linux-source-2.6.15 linux-image-2.6.15-19-386 (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed


Description:
I have an HP Deskjet 722c connected via parallel port which does not
work. The system recognizes it and attaches lp0.

I have applied the / to - change from bug #32085, cups seems to behave
better and it looks like the jobs complete successfully, but the printer
still does not work.

I have tried:
1. installing ppd file for this printer from linuxprinting.org (after changing / to - in *NickName*)
2. chmod 666 on /dev/lp0, not a permissions problem
3. turned debugging on in cups
4. Tried many different bios changes, ECP mode, irq 7 reserved and not reserved, PNP off and on,, etc, the printer is always recognized through these changes, but no go. Even resetting bios to defaults which is 0x378/SPP/irq7 does not work.
5. dpkg-reconfigure cupsys

Unfortunately I cannot echo anything raw to the printer. I know the
parallel port and printer work fine as I can boot into my other distro
(FC3) and bing, it works.

I did not try the printer in breezy, I just installed and did an upgrade
to dapper, but from the bootup in the breezy kernel I did get the
"PnPBIOS parallel port detected..." message, which I have not receieved
since going to the 2.6.15 dapper kernel.
