A simple X application supplemented with some of the libXp routines might look like:

/*
* Connect to the X Print Server
*/
pdpy =

XOpenDisplay( printServerName );

/*
* See if the printer "myLaser" is available
*/
plist =

XpGetPrinterList( pdpy, "myLaser", &plistCnt );

/*
* Initialize a print context representing "mylaser"
*/
pcontext =

XpCreateContext( pdpy, plist[0].name );

XpFreePrinterList( plist );
/*
* Possibly modify attributes in the print context
*/
attrPool =

XpGetAttributes( pdpy, pcontext, poolType );

/* twiddle attributes */
XpSetAttributes( pdpy, pcontext, poolType, attrPool, XPAttrMerge );

/*
* Set a print context, then start a print job against it
*/
XpSetContext( pdpy, pcontext );
XpStartJob( pdpy, XPSpool );
/*
* Generate the first page
*/
pscreen =

XpGetScreenOfContext( pdpy, pcontext );

pwin =

XCreateWindow( pdpy, pscreen, ..... );

XpStartPage( pdpy, pwin, True );

usual_rendering_stuff( pdpy, pscreen, pwin );

XpEndPage( pdpy );

/*
* Generate more pages, and so on...
*/

XpStartPage( pdpy, pwin, True );

more_rendering_stuff( pdpy, pscreen, pwin );

XpEndPage( pdpy );

/*
* End the print job - the final results are sent by the
* X Print Server to the spooler subsystem
*/
XpEndJob( pdpy );
XpDestroyContext( pdpy, pcontext );
