Convert .prn or .ps files to .pdf?

Does anyone know a minimal-hassle (and most importantly, free) way to convert .prn or .ps files to .pdf?

One of the files is just over 1MB; the other two are considerably smaller.

Thanks!

Probably Automator on a Mac?

Though I remember when we did the PDF files for the Carnival card games, we had to export every single PDF file individually from PS, so there may not be a satisfactory automated solution. Or maybe it depends on whether you need to turn layers on and off for the PDF output.

I just need these three files in a readily readable/printable format.

Not sure, but I think you can do it in Illustrator

Email them to me and I’ll PDF them for you. (But I only have CS4, it would have to be downsaved to that version or earlier.)
