It would be helpful if you gave a minimum of information about your setup. We don't even know if you are in a Mac or a Win machine; in fact, we don't even know if you are indeed using PageMaker.
Sorry I was so uninformative. I am using Pagemaker 7.0.
OS is Windows 7 Home Premium.
I have tried to edit the job options and I have saved my new settings - but I can't seem to
get a high quality PDF exported. I know that my file is good, because I have previously gotten
a high quality PDF exported from my older windows machine running XP pro.
Totally unsupported combination. Go back to your old machine or move to InDesign.
I believe you are correct. I went back to my old machine and made a copy of the distiller job options file that works so well. I then installed this file on my windows 7 laptop - and it still failed to make a high quality PDF.
Thanks for answering.
