Duplexing?
There seems to be two sets of comments on this article which is somewhat confusing.
I may have missed it, but the facility to do duplexing isn't mentioned. I'd guess that in this price range two sided printing requires a manual two pass approach.
I would also like to second the earlier comment about how good it is to see comments on Linux and Mac OSX drivers - many reviews don't mention this aspect. Within my family we have a Canon all-in-one networked B&W laser printer/copier/scanner and it is excellent except for the fact that it is Windows only and there is no support for either Linux or Mac OSX. (We use all three operating systems and have to transfer everything to Windows before it will print!)
