Yet another HP backend fail (USBs fault)

Wed Dec 7 13:58:35 PST 2011

Hi there,

I'm running a perfectly "zypper up"ed OpenSUSE 11.4 with CUPS 1.4.6.

I want to use a HP Business Inkjet 3000 printer connected via USB.

Problem:
DO
- Print one job
- "Paused - /usr/lib/cups/backend/hp failed"
- Resume printer
LOOP

What I googled:
- The /etc/cups/cupsd.conf-Fix: Replace 'sys' with 'lp'
That improved nothing, but led to some BS error messages
- Checked that /etc/cups/cupsd.conf belongs to the right Uid.
It did.

I eventually came up with connecting the printer via true LPT
(no LPT-to-USB adapter here, pure oldschool).
That, disturbingly, did the trick!

QUESTION:
I actually wanted to use the printer with another PC that does not
posess a parallel port, so it's gotta be USB.
Anyone got an idea how to work that magic?

Error log for USB-connected printer:
