The information in this article applies to:
  • Microsoft Win32 Application Programming Interface (API) included with: 

        - Microsoft Windows NT versions 3.1, 3.5, and 3.51
    - Microsoft Windows 95 version 4.0

Windows-based applications have used ExtDeviceMode() to retrieve or modify device initialization information for printer drivers. The Win32 API introduces a new function DocumentProperties() that applications can use to configure the settings of the printer.

Note that ExtDeviceMode() calls DocumentProperties(); therefore, it is faster for applications to use DocumentProperties() directly.

Specifying the DM_UPDATE mask allows an application to change printer settings when using DocumentProperties(). Applications should be aware that the GetProcAddress() function is now case sensitive.

Windows-based applications running on Windows NT (WOW) can call ExtDeviceMode(). The spooler's ExtDeviceMode() entry is intended for WOW use.
