I have a builder for my non-print documents, but it seems that I can't apply the normal builder to a printer document because of the way java print services works. If I were to apply the builder directly to the printer, it seems that I would have to somehow enter the print method in the builder and then have the director call the builder while it was in the print method, but that's not possible. So instead, I'm trying to build an image and pass it to the printable. But as you have pointed out, this is not a nice solution.
