Hi António,
Thanks for the interesting suggestion and link.
Using your suggestion, I added this to drawWithBox: in my subclassed
PDFPage:
NSLog(@"drawing to screen: %@", [[NSGraphicsContext currentContext]
isDrawingToScreen] ? @"YES" : @"NO");
Drawing to the screen returns YES. However, just opening PDFView's
NSPrintPanel returns NO - that is before the user chooses to print or
cancel, etc.
I'll keep testing it and to see if I can get it to work. Perhaps I
should check isDrawingToScreen in a subclass of PDFView rather than
PDFPage.
I don't mind if the destination is a PDF or EPS so that part is easy.
The numbers would still increment if output was generated.
Thanks,
Will

An alternative may be to try to leverage NSGrahpicContext's
isDrawingToScreen. A return value of NO may mean that the drawing
destination is a printer, but the destination may also be a PDF or
EPS file, so you need to set up a way to make sure you're not
drawing to a PDF or EPS file when you call it. Once you have that
set up you can add some code to your PDFPage subclass's drawWithBox:
method that sets a flag to indicate the page was printed and/or its
number was used.
