Would it make sense to make the API in such a way, that developers can 
easily extend the options in the standard dialog with new (pages of) 
advanced options, like booklet printing, 
two-sided-printing-on-one-sided-printers, N-up, etc.? That would mean 
API for both manipulating the printing dialog, and for being able to 
install a filter in the output chain somehow. However, you seem to know 
a *lot* more on this than I do, so I have no idea if this is realistic.
