Convert SNP (MS ACCESS snap shot) to PDF with C#

Question

Hello.
I am trying to convert MS ACCESS XP report into PDF.
For that, I am building C# web service, which receives as parameter path of SNP (MS ACCESS snap shot) and prints it(to PDF printer driver).

I used the code, to print, from http://support.microsoft.com/kb/322091
This code however, opens the printer, but doesn't actually print anything (regardless if it's a PDF printer or just regular printer))

How can I print SNP to printer from C#?

Thanks, Roy
