Returns the major version if the X Print Service Extension exists, else zero.
Returns the minor version if the X Print Service Extension exists, else zero.

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. If the extension is supported, the major and minor version numbers are returned to indicate the level of X Print Service Extension support.

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.
