Reading postscript 3.0

[antongiulio05 <antongiulio05@gmail.com>]

Hi,

I use Kghostview to read postscript texts. However, when postscript is:

PostScript document text conforming at level 3.0

I got blank pages. Maybe is/are right package/s missing? In apt-tree I have found nothing...

Thanks,
Giulio
