How to print a JTextArea?

Hello,
I'm trying to implement a printing mechanism for JTextArea but I have
a problem on extracting lines from it.
I used the xample found at http://java.sun.com/docs/books/tutorial/2d/printing/set.html
(PaginationExample class) but, instead of having available an array of
String (textlines), I have a JTextArea.
I need to replace the instruction

g.drawString(textLines[line], 0, y);

at line 93

with another, taking lines from the textarea.

Dou you know how I can do that?

Layne,

Ever since JDK1.6 the JTextArea has a method called getPrintable that
it gets from JTextComponent. You could start there instead of writing
your own printable.

Sorry but I can't use JDK 1.6
May you suggest an alternative?
Thank you and bye.

Personally, I'd likely implement a Printable that used the text area's
paint component method. The drawback is that you would need to
calculate the page breaks. There are lots of examples on the internet.
Here is a link to one solution that you can get to by a google for the
terms Printable JTextArea.

Ever since? You say that like 1.6 has been out for ages when in fact
it's the latest version available and only came out within the last few
months.
