.SH DESCRIPTION
.LP
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.
