通过IIS使用ghostscript打印pdf

Question

I referred this code snippet (http://stackoverflow.com/questions/2599925/how-to-print-pdf-on-default-network-printer-using-ghostscript-gswin32c-exe-she) and it worked very well. i can able to print a file silently from my wcf service.

But am getting a problem if i run this via IIS. means "http://localhost:5030/mywcf" work perfectly. if i change it to "http://172.16.16.1/mywcf" then am facing the following error. here is the stack trace.
