Almost.  The ca(a)nvas does not play any part in the most
straightforward pipeline, which is

	app -> gnome-print API -> metafile data -> server/rasterizer
	-> printer driver

The first three steps would not ever change, since after you have
metafile data you can pipe it to the server/rasterizer or to the print
preview rasterizer or whatever.

(Of course there is a separate communications channel in the opposite
direction so that you can query the print system for a printer's
capabilities and other funny stuff).
