Hi Olaf, No, there are no other commands apart from various ESC S, and then ESC s for data reading. It appears very simple compared to, say, the pixma protocol. Once I have a few more log files I will write out the protocol here, so far I have only clearly identified the resolution command, and data reading, and what are presumable ready/OK pairs. So maybe Canon just created some pre-pixma command format.... I can rip out all the complicated stuff in the pixma backend and try to make a new backend to support this. I figured though it might be easier to rip out things or replace commands in a backend that uses ESC/P style commands already. Regards, Gernot Hassenpflug
