Canon BJC-5100 1440 720 black/color, color/photo, or black/black cart pairs http://www.ccsi.canon.com/bjc/bjc5100/index.html F If someone believes this printer works -clearly document how to get it to work HERE. It simply does not work since the protocol is proprietary and undisclosed. <br>From all accounts, this printer does not use the same protocol as the BJC-4x00 line or the BJC-600. No free driver is known to exist, and the protocol is not known to be documented.
