This line of Canon printers sets the bar for the others, with its rock solid build quality and smooth operation

HP's ADF really is a loud, flimsy, half-@ss piece of garbage compared to Canon's.-Smooth, quiet operation from printer and ADF-1 GB RAM vs only 256 MB on the HP M477fdw-80 MB of secure print storage space built in vs external USB stick required on the HP M477fdw-Too many features to count, one of which being Google Cloud Print.-Great price!

Duplex operation is great

No official Linux support, but this can be worked around using the "CUPS Cloud Print" Google Cloud Print driverThis printer has rock solid build quality, beautiful printing and quiet, speedy operation.

The printer apparently layered all the colors (and black) to make the "black" text (it also slowed way down as it was processing).
