Not printing!

[linker]

Hi guys

Everything about network printing was fine on my kubuntu. Recently i have no idea why, it stopped printing. Now all i get is something like this (regardless of the printer):

-12345x2pjl set PAGEPROTECT=AUTO
@PJL SET RESOLUTION=600
(...)

I've tried to reinstall cups and to install the SVN version but nothing works. I guess this is coming out of some package upgrade i made (official one).

Does anyone have an idea?

thanks...
