BUG PDF Creator - oversizes papersize

I have created with print management new paper size with 4650mm / 297mm with PDFCreator driver you can't print this size - it still converted to A4 also print preview is viewed A4.

But if you print with PDF Architect you can show preview of this big size and also you can print to PDF.

Why is so different PDF Creator and PDF architect??
Or why PDF creator have this limitation??
