Print to A1,A0 problem. always A4!

I have this problem: printing from CAD, PDFCreator creates only A4 instead of A1 or A0. This is a new problem for me; I use PDFCreator since 10 years!
Anyone else have this problem.

I have the same problem with A3 page format. The text program used is Lotus WordPro under Windows 10. The page format specified in both WordPro and PDFCretor is A3 landscape, the output from PDFCreator is always A4 portrait. I have tried with option 'use printer driver setup' on and off, no difference.

Today I tried with 7-PDF freeware:

and it works fine.
