Just a reminder on how to print to a Canon Pro9000 via an Airport Extreme or a Time Capsule. This is actually tricky. You have to download the generic Canon IJ Printer (http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&fcategoryid=182&modelid=12892#DownloadDetailAct)
This has pretty tight requirements:
* Mac OS X v10.5.3
* Latest version of Airport firmware
* Pro9000osxcp10120ej7.dmg which is the 10.1.2.0 version driver.
