Slackware 13.37 64 bit.

I have an HP 5940 and a 7960 sitting on my desk. I can print to the 5940 just fine, but when I print to the 7960, it tells me it has lost connection to the printer, and the printer itself appears to have locked up - none of the controls work, and I have to unplug it and plug it back in to get it to do anything. This same printer works perfectly with Windows.

I'm using hplip 3.11.5, but it did the same thing with older version.

I'm not quite sure how to troubleshoot this. The fact the printer works with Windows makes me think there is nothing wrong with the printer itself, but now can printing to it via Linux make it lock up?

There has been a problem with Ghostscript, fixed and available as ghostscript-9.02-x86_64-1_slack13.37.txz at your favorite Slackware mirror in the patches/packages directory.

Although it may not matter, the current version of HPLIP is 3.11.7, which you can find at http://prdownloads.sourceforge.net/h...-3.11.7.tar.gz; edit the SlackBuild froum your source directory (just change the version number) and install it as an upgrade. Can't hurt, might help.

I might be a good idea to try removing your printers from CUPS and then re-do hp-setup (which will add your printers to CUPS).

Hope this helps some.

Did that - upgraded to 3.11.7, deleted printer, added it back. No matter what I try to print, even a test page, the printer locks solid, none of the controls work, power button doesn't work, and I have to pull the power cord and plug it back in to get control.

So maybe the question I should ask is, are there other ways to print? I'm using cups, and hplip. Are there other ways to print that don't utilize these? This printer works fine from Windows, but locks solid when I try to print from Linux, and nothing I've tried (not that I know enough to try much) has helped.

PS: This gets even better - if I unplug the power supply for the printer, about once out of five times or so I get a kernel panic :-)

I also notice that about 5% of the time, if I plug in a usb stick into my usb hub, I get a kernel panic. I'm thinking of upgrading to a newer kernel, I'm using the 2.6.38.7 huge that comes with slackware current.

Wow, we have a 3.0 kernel series? When did we graduate from 2.6 right up to 3.0?

FWIW I solved the problem by removing the hplip package, and using the hpcups 3.11.3a driver. In retrospect, I'm not sure what the hplip package gave me that I don't already have, other than a fancy ui.
