SUMMARY

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.
