As I do not know the exact setup of your system and your print queues
(nor the version of distro, CUPS, Ghostscript and foomatic-rip you use)
I was unable to give you a definite figure.

But since you seem to have a very limited environment, with one printer
only, it shouldn't be a problem for you to calculatat all possible fil-
tering chains for your print clients (which seem to be some kind of MS
Windows, guessing from your mentioning of "domain controller".

So (again guessing) the "all possible filtering chains for your print
clients" go down to this one alone:

  application/postscript
             |
             |         <----- pstops        # cost : 66
             v
  application/vnd.cups-postscript
             |
             |         <----- foomatic-rip  # cost : 100, or whatever
             v
  application/vnd.cups-raw

It's as easy as adding two figures, and then setting the FilterLimit
value lower than that. In above example any non-0 equal or smaller than
165 should work.

You seem to be an experienced enough user to even find out with 3 or 4
"trial and error" tests what a working setting will be for you and your
environment.
