Nothing showed for Printer Features trying to print from Preview app.  I also tried BBEdit (a great text editor) and it crashed as soon as I opened the Printer Features menu.

To clarify: use simplified PPD files with all of those tests.  If STP_PARAMETER_LEVEL_ADVANCED4
works, don't bother with the others -- the problem will lie elsewhere.
