Help on retrieving values from documentproperties before printing

Good day!! Is there a way to retrieve values / changes from
documentproperties? documentproperties is the screen is shown when you
press 'properties' on the 'Print' window. This can be derived from
winspool.drv. I was able to show the screen but my only problem is, as
I have mentioned before,how to get the changes made by the user.
Sample values are the number of pages, and orientation, etc..

by the way, the reason why I want to retrieve the values is because we
have a customized print screen. I just want to make that changes made
on the documentproperties reflect that of the print screen.

many thanks!!!
