"With simple multi-function machines available for well under £100, it's
legitimate to ask what extra value you get my paying over £200 for the
high-end PIXMA MP830 from Canon. The specifications give some of it
away, with things like duplex printing and duplex scanning from the
Automatic Document Feeder (ADF), a paper cassette as well as a paper
tray and direct printing from memory cards and PictBridge cameras."
