I did so mxsoxsns10ea Annoying to have to spend so much time tweaking the system though. The first reply in your string recommends installing a slightly older driver. Apple Canon Printer Driver 3.0 for Mac OS The drivers provided by Apple do not work. I was unable to scan from my MX after upgrading to SnowLeopard. Something is broken with the newest drivers as distributed by Apple. I have a MX, and could not get the 'Add Printer' dialog to locate my printer on the network. Responses from the scanner are sent back to the computer TO port I doubt downloading those will change anything? I have an MX and while the scanner component of the driver works great over the network, the printer component only works when you connect via USB. The outgoing packets will be allowed by the rule described above.
