Limit on PostScript custom Page Size?


I'm having trouble with printing with the use of "postscript custom page size", when I select the option fill in 393x210mm, click "OK", and "OK" in "PDFCreator Advanced Options" window and "PDFCreator Document Properties", everything seems fine...
If I go back in to check the the "page size" in "PDFCreator Advanced Options" it is changed back to default A4 :frowning:
Im trying to use PDFCreator from Word 2019

Can someone explain why the page size is changed back to default A4?

Nope, I even don't have better experience of using such PostScript. I will also be highly glad if I get some more details.
