Description Frans Thamura 2004-04-05 04:56:27 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.1)

Description of problem:
I use default cups from Fedora Core 1, and I try to print a test page
using 2 printer, 1 HP Deskjet 845c and HP LaserJet 1000. I try HPLJ
1000, and they always said media tray empty, that is silly, the paper
is in the tray.

I try HP 845c, same, cannot print, but when i change to 895c, the test
work, but when I try to print. using gedit, the paper is not working,
cannot print to it.

Several people in the chat room said, must install from source.

I think this is not a good statement.

I can guarrantee the USB is work well, but I think there is a bugs
also in USB driver, if the cups is stable.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. run redhat-config-printer
2. select printer
3. click test cups page

Actual Results:  cannot print, and the error is media tray empty

Expected Results:  test page show up

'media tray empty' is a kernel bug.
Comment 2 Pete Zaitcev 2004-08-19 19:01:30 EDT
This has to be resolved down to results of "cat > /dev/usb/lp0"
and its results, or an strace output before I can figured it out.
Comment 3 Tim Waugh 2004-08-20 04:29:26 EDT
Hmm, I retract comment #1 -- while I had always been led to believe
that it was a kernel bug, it turned out to be a misinterpretation of
status bits on the part of the CUPS USB backend.

However, the 'media tray empty' message is harmless and does not cause
any other symptom.
