/*+/csubr/TOC----------------------------------------------------------------* PlPrtClose - close a print job for a Windows printer** Purpose:*		Closes a print job for a Windows printer.  "end page" and "end*		document" commands are sent to the printer.**		After closing the print job, this routine wraps up operations*		for the PL_CTX for the printout.** Return Value:*		PL_OK, or*		PL_PRT_CANCEL  if bAbort is 1 or if PlPrtStatusWindow has been*					called and the operator clicks Cancel, or*		other codes for other errors** Notes:* 1.	If bAbort is 1 (or if pPlot->bPrintCancel is 1), then the printout*		is aborted, so that nothing is sent to the printer.* 2.	This routine automatically calls PlotWrapup.** See Also:*		PlPrtOpenDefault, PlPrtOpenDialog, PlPrtStatusWindow**-Date     Author		Revision* -------- ------------	--------* 06-08-95 R.
