printer problem: hplip/cups/permissions?

[equaeghe]

Hi,

I've got an hp920c on a usb port with hplip/cups as the print system.

This worked... a while ago. Now (some updates later?), I can't seem to print.
Everything gets pushed to the spool, and the print system thinks all is well and printed, but the printer does not react.
This happens with test pages from kde-print system, cups-webinterface and the hp utility.

Re-emerged hplip and cups, to no avail...

Tried as a user

what are the permissions on /dev/usb/lp0 ?

I have the same exact problem. My permissions are

[bobspencer123]

do you have similar problems with other usb devices?

make sure you have permissions in applicable groups:

I've solved my problem by unmerging ghostscript-gnu and emerging ghostscript-esp
It looks like this path issue with gnu-ghost was the trouble. Someone needs to fix that ebuild.
The fact that as a user I can't print to /usb/lp0 doesn't seem to be a factor, neither that I'm not in the lp group. Cups prints just fine.

@batistuta:

I use the latest stable ghostscript-afpl and my path seems to be in order (without the printing though):

equaeghe: can you generate pdf from KDE/Gnome? If yes, then your ghostscript should not be touched. Can you enable the debuging in cups and try again, then show your cups log?

@batistuta:

Using any of the other ghostscripts did not change anything, I still can't print.
Even without any ghostscript, nothing changes.

Something to remark, however: printing to a pdf file is no problem.
Probably ghostscript has nothing to do with my problem.

Grmbl! This is a real bother, printing is something that should just work, certainly when it used to fine...

please enable the debugging in cups

Edit the file /etc/cups/cupsd.conf
Change the line LogLevel to debug.

run
/etc/init.d/cupsd restart

print something

check
/var/log/cups/error_log

[equaeghe]

I get the following type of output in error.log + similar stuff in access.log + nothing recent in page.log

[batistuta]

is that the output from cups? Doesn't look like mine

Well, that was what I saw yesterday.

The log of today, after starting the computer and trying to print one pdf page (at end of post; long!)
Hope I can glean something from it. All I can see is a successful printjob ... at first sight ...

But wait, I see one error:
