I have a HP Officejet G85 and I just upgraded my system, which included the whole printer subsystem, and lost my printing. I have tried adding it via KDE's print dialog as well as directly via CUPS (localhost:631), to no avail.

uname -r: 2.6.26 (Debian)

When I attempt to add it via KDE, here is what I do:
1. /etc/init.d/cups stop
2. Unplug printer.
3. /etc/init.d/cups start
4. Plug the printer back in (in the hopes power cycling the printer will help CUPS find it; but I've also done this without power cycling).
5. As root, start "kcmshell printers"
6. I have two choices in adding printers in the "tree view" it gives me
a. Under USB, (and it IS a USB printer) I have "HP Officejet G85 USB #1", and under that I have "HP Officejet G85".
b. Under "Others", I have "HP Officejet G85 USB SGG11E4KXHVL HPLIP", and under that I have "HP Officejet G85". I also have "HP Fax (HPLIP) under "Others".
7. If I select 5a, I get the printer model selection dialog with HP and G85 preselected for me.
8. Next I get my choice of three drivers:
a. HP Officejet G85 (foomatic + cdj550)
b. HP Officejet G85 (foomatic + gutenprint-ijs-simplified.5.0)
c. HP Officejet G85 (foomatic + gutenprint-ijs.5.0)
I select b (selecting "a" then "Driver Information", it tells me a "should work, though not very well").
At this point, kcmshell hangs and quits refreshing it's dialog. This is in the CUPS log:
I'm not sure any of these "error-not-found" lines are relevant, because they could have occurred before I started adding the printer when kcmshell was trying to find what printers were out there.

Killing kcmshell and restarting it, or checking with localhost:631, shows no printers added

When I choose 'a' in step 8, above, kcmshell doesn't hang, and I get to where it asks me to print a test page, which I tell it to do, it says it sent it OK. Nothing prints, and nothing is in the job queue.

Now, go to add the printer directly with CUPS, (localhost:631), here is the sequence of events:
1. First, remove the printer in kcmshell and reinitialize, as in 1-4, above (verify, at localhost:631, on the "Printers" tab that no printers exist).
2. Now, click on the Administration tab and "Add Printer"; fill in name, location, description.
3. Select "HP Officejet G85 USB #1 (HP Officejet G85)" under the Device pick box.
4. "HP Officejet - CUPS+Gutenprint v5.2.3(en)" is auto-selected for me in "Model/Driver for G85". Click "Add Printer".
5. Next, a screen with a bunck of configuration options is displayed; click on the "Printers" tab.
Voila! There's my printer.
6. Click on "Print Test Page"; the job shows up in the queue.

Nothing happens; the queue empties (i. e., the job disappears), but nothing prints.

Now, if I delete the printer in CUPS and add it again, but this time, in step 3, select "HP Officejet G85 USB SGG11E4KXHVL HPLIP (HP Officejet G85)", same Model/Driver, the "Print Test Page" job goes into the queue and hangs there at 19%. This is in the cups log over and over:
</post>
but I think it has to do with refreshing the browser screen as opposed to printing (but I'm certainly no expert).

There is a program called "gs" that appears to be hung as well:
Syslog shows the following, over & over:
dmesg shows:
I have searched all over the web for a couple of days, and can find similar stuff, but no resolution. I think it may be new (I just upgraded most of my system) in the latest releases of cups/hplip/...etc. Also, after the upgrade my hp-toolbox quit working, telling me I don't have qt4 installed, which I do.

TIA!

When I put this printer on a paralled port with the "HP OfficeJet G85 - CUPS+Gutenprint v5.2.3" driver, it works.

Is this a bug in all this new printing software I need to report?

Well, almost works. Can't print from any Java app, but can print from all other apps.
