I am especially interested in frameworks for printing, and wrappers that provide a canvas interface to a printer.  I found a copy of Sophie 1.04 that has some code in Sophie-Printing.  Is there anything else I should study?

Under Linux, the lingua franca for printing is PostScript. So if you can generate a PostScript file you're almost settled. How to send this to the printer is unfortunately dependent on the environment - you need to make the command configurable, and perhaps make a good guess at a default.

PostscriptCanvas is a place to start, but depending on your app's needs might require some fiddling. OTOH, writing PS files from scratch isn't that hard either.
