Problem with printing (hplip) in Ubuntu 14.04

You need to run hp-setup after installing Ubuntu 14.04.

hp-setup Installs HPLIP printers and faxes in the CUPS spooler. Tries to automatically determine the correct PPD file to use. Allows the printing of a testpage. Performs basic fax parameter setup.

Run hp-setup, then if the problem still persists follow these steps, too:

1. Go to http://localhost:631/, then go to "Printers", there your printer will be listed under queue name, click it.

2. Click "Administration" drop down menu

3. Select "set allowed users"

4. Type in your computer "username" and "select allow these users to print" and click "Set allowed Users".

I successfully got the printer running using these steps in Ubuntu 14.04 LTS.
