## Description

XpQueryVersion determines if the X Print Service Extension is present. A non-zero Status is returned if the extension is supported, otherwise a zero Status is returned.

The X Print Service Extension is initialized on the first call to any X Print Service function; there is no need to explicitly initialize the X Print Service Extension.
