Have you used Sun's on-line Java tutorials?  Great place to learn.  The
main URL is: http://java.sun.com/docs/books/tutorial/

Regarding your print dialog, yes, you can use one.  Here is a link to the

printDialog() method to prompt the user for printer, number of copies,
etc.:

Here's a more general reference to printing.  It too gives a dialog
example that may be even easier to follow:
