Comment 11 for bug 877793

Hi,
This worked in installing the plugin :)
And then the printer was found and connected too with HP Device Manager. I printed a test page which also worked =]

However the drivers for the scanning do not work :(
I tested the scan option with HP Device Manager and got an error dialogue box, which I have included as an attached tar ball. I then ran:
hp-scan -g and got these results:

$ hp-scan -g

error: Unable to locate device hpaio:/net/HP_Color_LaserJet_CM2320nf_MFP?zc=NPI7887E4 using SANE backend hpaio:. Please check HPLIP installation.

I also ran the same command on another machine that has 11.04 and it worked, I have included the capture for that 11.04 install in the attached tar ball. As you can see it can find 'hpaio:/net/HP_Color_LaserJet_CM2320nf_MFP?zc=NPI7887E4'.
Therefore the network and the printer are fine and it must be something to do with the installation of the drivers :(

So, a lot of great progress but now, only scanning fails :(
