Well, what can one say. Blaaaaa!
Again, I uninstalled 1.6.2 and replaced it with an install of 2.5.1
I've done a number of tests with different configurations, below are two that sumarize the results.
Ran the original OvPro DTP app.
Opened the print dialogue, set the (My created) large page.
Continued with the print to PDF.
Afterwards it opened in Foxit PDFreader, all I have is an A4 sized part of the large document.
Into Windows, Devices and Printers, Print Server properties and created a completely new meduim size form.
Ran the DTP app with a new smaller file and did the print process, selecting in the print dialogue the new medium size form size.
End result the same, the eventual PDF contained only an A4 sized piece of the whole document.
Used a different DTP app Serif' Page Plus X9 (I'm assuming you will have heard of that app).
I'm in the process of manually transcribing one of my original files into PPX9.
So I now have a 2kmm x 350mm PPX9 document.
Prepare to print from PPX9
Using PDFCreator, set up its print dialogue to use the large 2K350 form.
It prints to PDF correctly, thus when opened in Foxit PDF reader the whole document is there.
Obvious conclusion, OvPro is not interfacing with new revamped PDFCreator correctly, particularly with new user created Forms.
[Not forgetting it works perfectly okay with 1.6.2]
I know and have contact with the Author/Coder/creator of the OvPro app, I'll have a chat with him sometime and see what he thinks.
A final thought... I still don't like the new PDFCreator config pane and its dialogues, poor design to say the least...
