>That's what I wanted to do, but from what I can see in the Acrobat docs the PrintPagesSilent method (I didn't mention it in my first message - I'm using Acrobat via OLE) only uses the default printer. If you want to change the printer you have to use a method that brings up a modal print dialog.

E.R.,

Sounds like you will need to make some API calls to temporarily change the default printer to the Winfax driver and then change it back after the PDF has been faxed.

Laterness,
