Parallel port problems with cupsys

[Graham White]

I have Ubuntu Dapper installed, with cups 1.2.2-0ubuntu0.6.06.
I have an HP Laserjet 1300 attached via the parallel port.
When I try to print from it, it goes into a loop of "check device; will retry in 30 seconds...", and I get a repeating set of messages in syslog
(attached). I'm also attaching the usual configuration files.

This printer was fine, both under breezy and under dapper, until
the latest upgrade of cupsys.

Thanks for you bug report.
Could you also provide the cups error_log:
1) change LogLevel in cupsd.conf from warning to debug
2) restart cups: sudo /etc/init.d/cupsys restart
3) print something
4) attach the relevant parts of /var/log/cups/error_log

Done.

Can you try if setting up a raw queue printer gives any output.
In CUPS web interface or gnome-cups-manager: Add Printer, select Manufacturer Raw, select Model queue.

I've done that for both printers (the Epson which features in Bug 55656
and the HP in Bug 55663): both print small text files perfectly well.
However, I'm still a bit sceptical about the Epson, because the fault
always used to be a bit sporadic, and, in particular, it would usually
print a page or two after rebooting before it would start misbehaving.

One more thing about the parallel port: I get messages like

Aug 16 11:24:53 localhost kernel: [68538.182942] ppdev0: negotiated back to compatibility mode because user-space forgot

in /var/log/syslog, whenever the parallel port printing terminates (on the rare occasions
when it happens to work, that is). Which argues that there's something wrong
with the parallel port implementation.

You are missing:

Listen /var/run/cups/cups.sock

in ports.conf

But that's not the problem. Issue here is in hpiod, which is part of hplip package or in parallel driver.

What kernel do you use (uname -r)?

What is the output of:
$ cat /var/log/messages | grep par

Do you still have this problem on Ubuntu 7.04 (Feisty) ?

[Graham White (graham-dcs)]

I don't really know (the machine I had with a parallel port died a while
back).

Sorry about that.

This was probably a hardware issue.
I hope you don't mind I close this bug since the machine you had the problem with died and nobody else confirmed this problem.

[Graham White (graham-dcs)]

Thanks. I agree: probably hardware related.
