Thanks Gareth, I do have the have the other appcf file on the APE. The poscript.appcf is also in the folder but, PTC hides it. If you use print composer there is a browse button that you can use to select it. The reason we would like to use the post script publisher, is that we cannot seem to get our pdf sizes anywhere close to what Adobe distiller creates for us. I have modified the templates and created a web and standard versions. They both create the same size pdf that are way to big to use anywhere. i believe the issue is with our graphics and conversions. We are using cgm but contemplating moving to svg.
Yeah I'm not sure the built-in PE integration has a publish-to-postscript feature. That's why it's hiding the PostScript option. You have a couple options:
PE subscription "registered user" license is a really cheap way to get desktop-based Print Composer replacement. This *should* be able to publish-to-postscript (you can verify by testing PE Interactive on your current server).
Let PE make the large PDFs and use Adobe to shrink them. The Adobe software can shrink PDFs pretty good.
