[net.micro.mac] Printing on a LaserWriter

merchant@dartvax.UUCP (Peter Merchant) (05/20/86)

I'm using TML Pascal and I'm trying to print on a LaserWriter.  It works fine,
but when it's done PrPicFile returns a -192 (on a call to PrError).

-192 is a Resource Manager error of "Resource Not Found."

Now, it works.  It prints.  I'm just wondering what this error is about.

PrPicFile should only be called when you are doing spooled printing. Since
the LaserWriter driver does not spool, you should not call PrPicFile. The
code to call PrPicFile in a printer-independent way is:

	{Variables}
	hPrint : THPrint;
	prPort : TPrPort;
	prStatus : TPrStatus;

	{ Code Fragment }
	if (PrError = 0) and (hPrint^^.prJob.bJDocLoop = bSpoolLoop)
	  then PrPicFile(hPrint,NIL,NIL,NIL,&prStatus);

This will make sure that PrPicFile is only called when appropriate.
