Hi all,
I too am trying to get a Canon 4200 to work via AirPort Express. It is compatible as others have confirmed.
I can do basic printing OK. However, it will not print double-sided via APEX - although it will print double-sided when the printer is connected directly to the computer. (It will only print double-sided if I select 'automatic duplex printing' as the last option before pressing OK, and does not remember this for the next time I print - but that is anothe issue.)
I would be grateful if anyone can confirm the compatibility of double-sided printing on a 4200 via APEX, and provide any hints as to what I have not set to get this to work.
Thanks,
Daniel.
