A quick-and-dirty solution is dumping the window using xwd & xpr
without user interaction.

First define a couple of things, the name of the window you wish
to dump & the name of the device to dump to.

/* name of the application when iconified & on window*/
#define APPNAME "statsgraph"
/* Postscript LaserWriter*/
#define PRINTERDEVICENAME "lw"

Then bind the following function to a key or to a button (via a callback 
mechanism):
void
laser_window()
{
char sysbuf[256];

    sprintf(sysbuf,"xwd -name %s | xpr -device %s | lpr -P%s -h", APPNAME,
        PRINTERDEVICENAME, PRINTERDEVICENAME);

    system(sysbuf);
}
