How to add a new paper for printer?

Hello. Is it possible to add a new paper using only PDFCREAT.PPD file? I doubled entries for A3 paper made only unique name, but after reboot this new paper doesn't show anywhere. I made the conclusion that to add new paper modifications for file PDFCREAT.BPD are needed but this one is binary file.


PS: what is the file PDFCREATOR.PPD? Is it from earlier versions of pdfcreator and is not needed anymore? I've got that and date of the file points on 2003 year.
