The printer driver is installed (via LinuxMint Petra 16 Cinnamon .iso installation process) but simply not printing, no response, zilch, niente!
It's not a network printer but connected via usb to my laptop.
I read elsewhere that MAYA or XFCE doesn't have that issue...
Update: a friend at DonationCoder forum http://www.donationcoder.com/forum/index.php?topic=36661.new#new helped me out with this tip:
"Lets try installing hplip and hplip-gui using either Synaptic or the Mint Software Manager.
Then, from the start menu, go to <Preferences><HPLIP Toolbox> and try installing your printer from there."
And it worked!!
