the IS-12 is a kind of a printer cartridge. You put it where the normal ink cartridge would go, and it turns your ink jet printer into a scanner. http://www.canon.co.uk/for_home/product_finder/printers/accessories/scanner_cartridges/index.asp by this question i can assume you're not working on it :) > How is it controlled by the computer - SCSI, USB or parallel > port? Perhaps one of the existing backends can be used. > Its controlled via the parallel port, and it would be safe to assume that a back end exists for the scanner chip set. I would guess its a chip set that supports single pass, and that its controlled by prefixing the control commands with a printer command. I don't know what the chip set is, and to be honest i don't want to take apart a my brand new IS-12 to find out. A cursory google for information on the internals has come up empty, so i don't know how to proceed other than running a port scanner under windows. Is there a method for matching command streams to a backed? Tim.
