Auto printing prints on printers that have not been selected

I have PDFCreator version 1.2.1 installed on a Windows 2008 Server /64 bits as a service.

I have created a profile where I do an autosave of a document and have specified that I want to print it to my default printer with no user control.

The thing is that the documents that I create are sent to my default printer and also to other printers in the system.  In this way I get multiple copies of a document that should only be printed to my default printer.

If anybody knows how to solve this issue, please let me know because I'm quite desperate.

Thanks everybody!
