Ever since 10.04, I can't print to an HP laserjet p3005.

I'm even using an entirely different computer now with a fresh install of 10.10. I've tried with and without the latest hplip.

Recently, sometimes I can get it to print a few things, but eventually it always fails (usually when printing a pdf from the document viewer (also doesn't work with adobe pdf reader)).

Sometimes it fails so bad the printer gives an error saying it needs to be turned off and on again.

I can't seem to find a fix anywhere, I've googled all over the past year and tried every fix I could find. It does say that the /usr/lib/cups/backend/hp has failed.

It also doesn't make a difference if I create the printer using hp-setup or ubuntu's own printing control panel. I delete and re-create the printer, no difference eventually. I use the default printer settings or custom settings, no difference.

I can print perfectly find to a networked printer at home - an HP officejet 6310. It seems to be networked HP printers at work that I can't print to anymore (except occasionally right after re-installing the printer driver).

What's the recommended way to install HP printer drivers and reset or clean out everything from before. Or where are the right logs to read or debug commands to do to find out what may be the real cause of the printing problems?
