How do I print a PDF silently?

My code:

ShellExecute(0, 'printto', lcpdffile, '"' + lcprinterName + '"', null,0)

This code launches the Adobe Reader and keeps it open on the screen.
We don't want to see the reader.


How about getting the Bullzip PDF Printer? Then all you do is:

SET PRINTER TO "Bullzip PDf Printer"
REPORT FORM Yada
