Connection error g85 hplip

Hi,

I tried to install officejet g85 on my ubuntu 12.04 computer.

I follwed the hplip....run (most recent version) that is provided on the hplipopensource website. When the hp-setup window opened, the printer wasn't shown (it's a local printer connected with usb). Then I used the lsusb command in my terminal to find the bus and device number (which is 003:004) and I manually added the printer via advanced options. This worked (it showed the correct printer name), but it gave the following error in my terminal:

Found device: hp:/usb/OfficeJet_G85?serial=SGF0BE29FPVL
\error: Unable to communicate with device (code=12): hp:/usb/OfficeJet_G85?serial=SGF0BE29FPVL
error: Unable to print to printer. Please check device and try again.

The hp-check -r i gives the following errors:
error: Unable to communicate with device (code=12): hp:/usb/OfficeJet_G85?serial=SGF0BE29FPVL
error: Device not found
error: Communication status: Failed

Previously this also gave an error on the lp/lpadmin, I don't know how but that disappeared (hopefully is fixed) now.

When I try to print a document, there is a popup saying there is a connection error, while the connection is fine (and printing works on Windows 7)

Does anyone know a solution ?

Thanks!
