Saving a PC format EPS, PDF or TIFF on a mac

Hi

I have a printer who is requiring a "PC format ONLY eps, pdf or tiff"

I've never encountered this problem before so I was wondering...

How do you save a PC format EPS, PDF or TIFF on a mac and what is the difference anyway?

Im using CS3

thanks!

Never heard of a difference here, very weird. But what program of the CS3 are you using? There are many different ones.
