Comment 4 for bug 1284970

Yes Thanks the problem was resolved. It just took a little more digging on the net . and did reinstall via HPlLIP found on the net. Result: HPLIP toolbox which contained "Install required plugin" and that got things rolling,ie called for a couple of more steps including reboot.
 Have not yet been able to make wireless available. USB is the only mode.
Just tested again before reply and after shutdown and restart.
I've been down this path before with this printer. It was one of the ones that masqueraded as a CD and had to use
#!/bin/bash

usb_modeswitch -v 0x03f0 -p 0x032a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n -2 474554202F6465762F666561747572655374617475732E786D6C20485454502F312E310D0A434F4E54454E542D4C454E4754483A20300D0A555345522D4147454E543A68702050726F78792F332E300D0A484F53543A6C6F63616C686F73743A333931300D0A0D0A -n -R

and then name the file 'hplip_usb_modeswitch.sh'

Subsequently, in the directory where the file is, just do in a terminal:

$ chmod +x hplip_usb_modeswitch.sh

to make the file executable. Now double-cliking on the file should do the job - you should have the option `Run in terminal' once you do so. Once you run it, you will need to disconnect the printer, turn it off, wait for 10 sec (power cycle), and turn it back on and connect, and it should be ready to roll!
to make it come alive
A tool I kept in reserve.
The tools available are not intuitive for me perhaps I'll remember now and trust HPLIP. after the masquerade problem I didn't trust HPLIP any more; It had gone completely out of favour with me and perhaps other folks as well.

Thank You Till Kamppeter!
