Hi: rsakols
Running Quark 6.52 on Mac OS 10.4.10 here.
Although the help files in Quark 6.52 say you can print all the chapters in one file, I cannot do that and print or export to PDF.
I think if you have Adobe Acrobat you can print each chapter to PDF and then use Adobe Acrobat to merge all the chapters into one PDF file.
Or if you google you might find another program that will merge multiple PDF files into one single file.
Unless there is a Quark extension to do that, I don't know of any other way.
Hope this helps
