Hello, recently i have the same problem until i found a freeware that can do that and more. this program is named pdfmailer and it creates a pdfmailer virtual printer so when you print the report you only choose the pdfmailer printer and that's it.
It only place a little orange banner at the top of the report but it barely notorious.

You can download it from the www.pdfmailer.com web page or www.pdfmailer.de if you can't do it, send me an email and i'll reply it to you with the file attached to it.

Hope this was helpfull.

Bye.
