Tube Coping Calculator with custom pdf page sizeIn this instance, "custom" means random. Sort of. It will attempt to make a pdf page that's a little bigger than your pattern. It will not make any sort of standard page size. If it's a small pattern, it should work fine in Acrobat Reader as long as you don't scale the page when you print it. If it's a big pattern, you're on your own. You could print it with a program or on a printer that allows you to tile it. Or import it to a CAD or illustration program and tile it. But if you wanted to do that, you could have just imported the postscript version and you'd have it printed already.
In any case, there's no guarantee that it will work. Let me know if you break it, but I may not be able to fix it anytime soon.
