PDF Silent Printing
Using Ghost script to print PDF
GSPRINT uses Ghostscript to print a PDF file to a Windows printer. Using Ghostscript alone you can print using a number of inbuilt printer drivers for specific printers (e.g. djet500, ljet4), or you can use the driver mswinpr2 which talks to the Windows printer driver.
Example: to print to a default printer
gsprint.exe c:\myreport.pdf
