Customized print sizes

[Andreas.Ebbert at gmx.de]

> I want to set some customized print sizes using CUPS. I am running Linux (Fedora Core 2) and I have found some choices of default print sizes but unfortunately they are not fit to what I want. Can somebody tell me how to use customized print sizes in X-Window?

Same question here. For what I know, the supported media types are listed in the printer's ppd (/etc/cups/ppd), but do I really have to edit this file manually, to be able to print on some custom sheets in the manual feeder?

(please reply also to my mail account)
