Serverside conversion of Infopath forms to PDF

[Stitch 2.0]

Hi all,

we need to convert Infopath forms to PDF files (view only, no edit) on
a server.

All solutions I have found so far require the actual application
installed, as they simply use the print function to print to PDF.

Has anyone heard about a server application who is able to do the
conversion WITHOUT using the printer? Or at least without using
Infpath?

Any tips would be really appreciated.

Thanks in advance!
