Ubuntu – Localhost printer stuck at “Rendering Completed”

I am unable to print documents using my HP printer. However, I am able to print test pages.

What I tried:

I have tried removing and re-installing the printer from the system settings but I can only print once (the first task). Then all the following tasks get stuck at the "Rendering Completed" status.

I additionally tried restarting the computer which leads in the same task mentioned above.

Moreover, I logged into the CUPS system ( 1.6.2) from http://localhost:631

From there, I removed the printer, restarted it and re-installed with no sucess.

System Specifications:

System : Ubuntu GNOME 13.04

Memory: 3.9 GB

CPU : AMD Athlon(tm) 64 X2 Dual Core Processor 4200+ × 2

OS-type : 32 bit

Graphics: Gallium 0.4 on NVA3

Printer: HP Deskjet 2050 j510 Series

IP Adress: localhost

I had no problems with my previous OS which was Pinguy OS 11.04 ( a distro based on Ubuntu 11.04) and it's the first time I use my printer at this OS.

Screenshots:

My printer stuck at "Rendering Completed" status.

From the CUPS web interface; you can see that "Rendering Completed" is stuck at the state of the print process.

**EDIT:**I tried printing from the pdf.js pdf viewer of firefox: I wait for about 5 minutes for a 10 pages document to print, the document is printed like faded and sort of in bold font (I accuse rendering for that). Then the status of the printer gets stuck at 'Rendering Completed' but I can print later on. Again, for the next prints I wait for 5 minutes minimum ( I wait for the 'Rendering….' bar to fill ) and the printing is weird.
