[plug] KDE, CUPS, PDF & Postcript

[Marcos Raul Carot Collins]

I have done that, same results.

There is a bug reported against Firefox 3 which generated Postscript 3 
directly and caused this issues too.

Apparently CUPS has a filter that converts PostScript 3 to 2 when the printer 
does not support 3. I guessed the first step was to let CUPS know that the 
printer only supported level 2, so I modified the ppd file as you say.

As the results are the same now I am wondering if the level 3 to level 2 CUPS 
filter is the culprit of the "yellow glow".

:S

Thanks William!

Cheers,

Marcos
