Thanks for your quick response Helge,

this is a very clever trick and it worked - in principle ...

I added your remarks to my ppd file (it didn't contain any JCL
definitions). But after updating the windows driver using cupsaddsmb
this section looks like this:

*%========================================================
*% JCL Features
*%========================================================
*% Commented out by cupsaddsmb...
*%JCLBegin: "%!PS-Adobe-3.0<0A>"
*% Commented out by cupsaddsmb...
*%JCLToPSInterpreter: "%cupsJobTicket: supress-setup-features-from-ppd<0A>"
*End
*% Commented out by cupsaddsmb...
*%JCLEnd: ""


I deleted the comments manually. Now my prints are colored. But why does
cupsaddsmb remove these configuration entries?
