Python win32print changing advanced printer options

I am using python 2.7 and win32print. I can successfully change the orientation between portrait and landscape:

PRINTER_DEFAULTS = {"DesiredAccess":win32print.PRINTER_ALL_ACCESS}  
pHandle = win32print.OpenPrinter('300LN1', PRINTER_DEFAULTS)  
properties = win32print.GetPrinter(pHandle, 2)  
pDevModeObj.Orientation = 2  
properties["pDevMode"]=pDevModeObj   
win32print.SetPrinter(pHandle,2,properties,0) 

However, I want to change some of the custom properties for my printer but can't seem to find where to do this. This is one of the tabs I want to change: http://dl.dropbox.com/u/584330/print.jpg. I believe that these options are accessible when one enables the "advanced printing features option".

Additional info (code):

devmode=pDevModeObj  
for n in dir(devmode):  
  print "%s\t%s" % (n,getattr(devmode,n))  

Output:

[edit] I just tried the following code:

win32print.DocumentProperties(0, pHandle, '300LN1', None, None, 5)

This would pop up the properties window I want to modify.

Also, do you know if it is possible to ask a printer to stop printing once it hit say 300 pages?

from ctypes import windll
windll['winspool.drv'].AdvancedDocumentPropertiesA(None, pHandle.handle, '300LN1', None, None)
