Let's see in theory you create a PrintJob Instance, then call

a) pageSetup (printSetup) once to setup printer stuff
b) preProcessing once or more to invoke the printer dialog
  printForm:  or printPostscript to print a page based on the form, or I'd guess
  multiple pages depending on what your postscript does.
c) postProcessing to cleanup and terminate printing for this PrintJob Instance.

 From my reading of the os-x implementation you can run multiple print 
streams, for os-9 only one at a time (I think) Other platforms will 
have different behavior.

The printForms: or printPostscriptPages: are really just convence 
methods to feed items to printForm: or printPostScript: Of course I 
need to feed a page number in there somewhere.
