index                Callable Print Serivces

synopsis

	 unsigned req;    /* Request Code */
	 char *file       /* File name or "" */
	 int *stat        /* --> 2-word status block */

	 p$cprnt(request, filespec, stat);

description

	Cprnt is a callable routine that allows your application to print a file,
	stop, continue, abandon or restart a print job, or obtain printer status.
	A request to print a file creates a non-interactive task.
	.s
	Request codes:
		+1 print file
		+2 abandon current print job
		+3 pause current print job
		+4 continue the paused print job
		+5 restart the current print job
		+6 report printer condition
	.s
	Remainder of the 75-word integer array is used as a temporary
	scratch pad by the CPRNT routine
	.s
	For more information please refer to the Professional Developer's
	Toolkit Reference Manual.

diagnostics

	The following codes may appear in the first word of the status array
	.s
	+1 -- Request accepted. If the request was "report printer condition",
	the second word returns one of the decimal condition codes expounded
	upon in the P/OS manual.
	.pg
	-1 -- Error occured. Second element of array contains DSW error codes.
	.s
	-21 --  Print service error occured. Second word contains decimal error
	code explained in the manual.
