PDF Printing Utility?

[Mothra]

Does anyone know of a decent utility to print existing PDF files from VB? I need to batch print without user interaction and I need to be able to programatically control the paper size for each print. Lastly I don't want to deal with watched directories, I know which files need to be printed and can pass those to the utility doing the work.

I tried using DDE and Acrobat Reader - which works fine unless you need to have control over the paper sizes. Any suggestions are welcome. More background on what I'm up to below...



My customer has quite a few TIFF files that are mostly scans or e-prints of architectural drawings. They have business software that generates a list of files to print. I developed a utility to parse that list, find the files, and print them. It checks the physical size and resolution of each file to determine what paper size to use (there are about 5 different paper sizes possible). I used a 3rd party imaging library to make this easier on myself and it's been working fine. Now I need to duplicate this functionality for PDF files, which unfortunately my imaging library doesn't handle. So that's it in a nutshell.

Thanks for looking.
