I'm now up to eight Canon dye-sublimimation photo printers, with two more bundles of joy on their way, all in the name of Free Software. It's interesting; a proprietary printer driver was the spark that spawned the Free Software movement, and I'm continuing the tradition with these.
The Gutenprint stack is far more capable than the original Canon dyseub printer drivers.
On a slightly related note, Anyone out there have a coloriometer I can borrow? I'd like to fully calibrate these things.
