Printing Reports With DLL through ASP Page

Hello Guys!!!
I'd make a DLL in vb6 to generate and print some reports using the Printer object. It works very well when runed into visual studio. But when I call the compiled dll through ASP page, it returns a Printer Error '800a01e2'. I need the reports be printed at client printer. I think that if a could atribute a driver name and a device name to the Printer object it would work, but this properties are just output.
Can somone help me please?
Tahnk you..
