Oh, absolutely. For sending to the printer, sending a PS document may cause problems. File size (in terms of both transfer and RAM necessary to open the file), program version, font and plug-in availability, and possibly some other things may all cause problems. Follow your service provider's guidance for submission, but where there's doubt, a simple raster file like jpg or png is safest. I'd avoid tiff as well, since it's not completely standardized.

Never use jpg as a working file format because each save iteration degrades the image's quality.
