It looks like there's a nice clean separation between two pieces: 1) A print dialog for selecting printers, paper sizes, printer features etc. 2) A rendering API to produce PS, PDF, SVG etc. Most programs will want (1), but only some will need (2). Most of the programs I've written don't have any use for rendering (making no use of the Canvas): they either output plaintext or do their own printer-specific control, or use groff or TeX as the rendering mechanism. They would still find (1) very useful, to select the output destination, paper size, print quality etc. With regards to (1), I did have a chat with Jody Goldberg about this in Bordeaux this summer. One issue we have in the Gimp-Print project is that the current mechanism of describing printer capabilities with PPDs is no longer sufficient to describe a Gimp-Print driver, which supports curves and value ranges which the PPD spec can't cope with. This becomes a problem when you want to edit them in a portable manner: currently only the GIMP Print UI is capable of this, leaving CUPS and LPRng users unable to access the extended functionality on offer.
