printing with CUPS and libusb, spooler hangs

[WalGrom]

Hi.

I've got a HP LaserJet 3030 Printer/Scanner/FAX/Copier
My computer is running a debian woody with Kernel 2.4.26 i386 SMP
Formerly, I used module printer.o and hpoj-printer driver classes (ptal-mlc for USB).
All worked (NEARLY) perfect.
But occasionally the system crashed while printing.

I found out (as mentioned on the hpoj website), that esp.
my combination (Kernel 2.4, SMP, module printer.o and USB-printing)
seems to crash sometimes.

O.K. - I unloaded the module printer.o as mentioned on hpoj-website
and I'm now using libusb 0.1-4.

The system does not hang, but the printing spooler does occasionally
after some pages of printing or sometimes does not start printing at all.
I see the printing tasks and can remove them but they sometimes don't print.

/var/log/messages and /var/log/syslog as well as some logs in /var/log/cups say nothing about libusb, ptal printer drivers or a hanging spooler.

Seems like an andless spooling loop...

Where can I search?

Thank you,
WalGrom


P.D.:
same problem on debian sarge, Kernel 2.6.8 i386 SMP, libusb 0.1-4.


[EDIT: O.K. I see on hpoj.sourceforge.net:
recent news, 18-april-2005: use HPLIP instead of HPOJ for USB-connected
devices....

I'll try.....and report.]

SOLUTION:
- works fine with kernel 2.4 or 2.6 (even with SMP)
- use hpoj.sourceforge.net driver (ptal...)
- do not load printer.o resp. usblp.o
- use libusb instead
- install an appropriate PPD-File (from linuxprinting.org) for the printer
- reinstall CUPS-printers (using localhost:631/admin webinterface)


The problem was not the driver architecture (HPOJ vs. HPLIP)
but the missing PPD-File.

...WORKS fine and reliable now - if anyone is interested...
