You can edit the sizes.dat file in notepad and add any that you want
My printer (Laserjet 1020) doesnt support custom sizes, unless I go to the printer properties and add it there. So I couldnt test it. So I have the program load all the paper sizes reported by the printer as before, I just label them Printer Supported and then the rest is loaded from the sizes.dat file. So now if a person has a printer that supports custom sizes they can use those, for people who cant use custom sizes, like myself, can use the printer supported ones.
Since the custom one worked for you then I think the program should be good to go. I will put out the new version later today or tomorrow. Thanks again for testing!
