Help with printing problem
Below is the code I have for my print class. It may be all screwed up, I tried as best I could to put something together that would function. I want a generic print class that can print whatever I send it, like an entire frame or the contents of a text box. This code works somewhat. When I print a JFrame it does not print the frame itself but it does print it's contents. But I want the whole frame with menu, contents, title, etc. Also I want it to print things to scale so they don't come out all huge, and also so stuff that is bigger will scale down to fit the page. Any help would be greatly appreciated.
