Helge,

"(short of that you attached 2 PPDs as one file)"

That is curious.  I attached the file
/usr/share/ppd/cups-included/postscript.ppd

and as you say, it contains two printer drivers.  Is this likely to 
cause any problems?  How is this file generated?
(I am using Debian Wheezy)

I have inserted the lines as you suggested, I will let you know how it goes.
