How can I print the values from a JTree to a paper

[sailsjam]

I have a JTree and I want to get the values from it and print it on a paper.The printing should be well formated.

[Cindy Glass]

And what exactly is "well formatted"?
This looks like a basic IO issue. Read the JTree, format to an output file. You need a PrinterJob to get the output file to paper.

Here is what I have so far in a conversion of PrintJText (another post in JavaRanch) to being able to print any JComponent. It will print a page of a JTree but does not understand page size so far. I just started on this but it looks promising.
