DLL VB6 + Classic ASP

 Hello,

I have an application running Classic ASP with  DLL developed in VB6. This DLL has got several methods, among them a method which runs the printing of a document. The application is running in a 2008 server with IIS 7 and when I try to print this document in a shared-network printer nothing is printed and also no error is reported. All methods of the DLL work perfectly, the printing is an exception. What can be happening?

Thanks.
