It is fairly normal for low-end scanners to do many features in
software. Given the price of the scanner in question, i would expect
it to be a little smarter than that. The size of your pcap files
should vary as you change the x/y values. I will also be more
explicit- there is no reason to assume the canon proprietary sane
driver fully exercises the capabilities of the machine. I would expect
the windows driver to be more complete.
