The "%cupsJobTicket: supress-setup-features-from-ppd" comment
is not generated by the PPD as modified by cupsaddsmb.

You need to edit the PPD on your Windows box(es) like this:
Look for the Keywords 
*JCLBegin
and
*JCLToPSInterpreter
until 
*JCLend
and change them to the following:
---snip---
*JCLBegin: "%!PS-Adobe-3.0<0A>"
*JCLToPSInterpreter: "%cupsJobTicket: supress-setup-features-from-ppd<0A>"
*End
*JCLEnd: ""
---snip---
This will do what you need (only when using the alternate pstops filter,
of course).

Good luck
