Printing with Book and paint()

Question

I'm posting this because I'm hoping someone can unconfuse me!
I'm trying to use a Book class, so the correct number of pages appears in the printer dialogue. However, I don't seem to be able to get this to work. My confusion is over the following. In http://java.sun.com/j2se/1.3/docs/guide/2d/spec/j2d-print.fm4.html (section 7.4.2) it has an example with the following three lines:
Book bk = new Book();
bk.append(new PaintCover(), pfl);
bk.append(new PaintContent(), job.defaultPage(), 2);
and it states this is used to print two pages. Yet the API states the third parameter 'Appends numPages pages to the end of this Book.' This would imply three pages are printed, one of PaintCover and two of PaintContent.
Furthermore, there is the pgnum parameter in the print() method. Now I would have thought that is tied in with this third Book parameter. But that seems to have a life of its own. It is supposed to be a zero-based index. But does that mean that PaintContent.print() will initially receive the value 1 (ie page 2), and be called twice (because of the argument 2) in the code extract above?
If so, do you need to have the Printable.NO_SUCH_PAGE return value in the method?
Perhaps my question should be: how do the third parameters of the Book class and paint() methods work, and how do they relate to each other.
As I say I am very badly confused, and any advice, help or otherwise prodding in the correct direction will be welcomed! :-)

Answer 1

Printable.NO_SUCH_PAGE is usefull when u r not using Book ..
ex, if you use
book = new Book();
book.append(this,pageFormat,10);
printJob.setPageable(book); it will print 10 pages
and
printJob.setPrintable(this,pageFormat); will print until you call Printable.NO_SUCH_PAGE - which is usefull when you dont know number of pages
