Help on retrieving values of documentproperties before printing

Question

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!!!
