If any of the properties of a printer are changed they are kept until the program is closed.

What i wish to do is store the printer properties

Allow the user to change then

Restore the printer properties

I use Report Pro 2.14 and VO28. If anyone has a better suggestion to keep the printer properties please let me know.

Win32 has an interface, to access / change the printer device properties via the Windows interface:
https://docs.microsoft.com/en-us/windows/win32/cimwin32prov/win32-printer

Could you read it, store it, let the user go to town, then reset it? I don't know how VO "wraps" this interface.

CurrentPageNumber
DefaultPaperSource
DeviceContext
DeviceModeFields
DisablePrint2File
