The other thing you don't have is 67 documents that were made with this same layout in Pages '09. Fortunately, you had mentioned that Pages '09 is still on our systems, just hiding in the Applications folder, or I would be in real panic mode right now. Thanks for that!
There are many things I need to try when I get more time. I list them here in case others are having the same problem.
Look at the Pages 5.2 Card templates and see if my setup can print them (although I suspect it's a full half-page card- (still a US Letter size-and not this smaller 7x10.)
See if any driver updates are available for my Epson Stylus Pro 3800. I seriously doubt this is the issue, however, since I can can the PDF version of the file perfectly, just like Pages '09 worked. Do you happen to know what controls the print dialog box? Is it the print driver?
Make a card from scratch to eliminate alll connection to Pages '09. I was really tempted to delete the custom page size I created before the update, but I don't want to mess up the documents that still use it. I still don't understand why my Page Setup in Pages 5.2 always returns to that page size. I even tried selecting my new custom 10x7 and doing a Save which usually saves the print settings and it still goes back to 7x10 the next time I open it. ( I did try creating a differently named 7x10 and it STILL went back to the original 7x10 which doesn't seem right)
See if there is any way possible my printer could print with the 10in side feeding in. Previously there was a limitation in that only the sheet feeder was able to print this small, and only up to 8.5" feeding in.
Any other suggestions?
Thanks for your help,
