Abstract
A printer driver having a 32-bit portion for providing a 32-bit property page for insertion into a standard Windows property sheet. The printer driver also has a 16-bit portion for exposing a device driver interface (DDI) entry point, and for providing a dummy property page when the entry point is called. The dummy property page is destroyed before it is displayed. Also provided is a printer driver having a 32-bit property sheet shell extension registered for printers. A 16-bit portion of the printer driver exposes a device driver interface entry point and which provides a dummy property page when the device driver interface entry point is called, the dummy property page indicating that a callback function is to be executed. The callback function signals an operating system to destroy the dummy property page before it is displayed.
