I read a few more of your posts and found the solution!. I just wrote the following on Amazon:
I wrote the message which follows this text out of frustration I was hoping others would avoid. I actually found the solution to the problem which I have below after the jump.
The error message: "Printer Stopped-Filter failed". I purchased this printer in January and have used it with my MacBook which has OS X 10.7 Lion. Works great via Airport extreme. I recently purchased a Mac Mini late 2012 model which has OS X 10.8 Mountain Lion. I made five calls to Canon and five calls to Apple over a 24 hour period. Each call was particularly time-consuming and frustrating due to the following. Canon and Apple says it is the other's problem. The Canon website and support personnel including the engineer consulted claim it is definitely supported by Mountain Lion. Apple's latest set of printers supported came out in January and not only is this printer not supported, BUT ALL of the MF (multi-function) printers are not supported...since they are not on the list. I have written and spoken to Canon that this printer may be supported by Mountain Lion to the engineers, but to the consumer, it is not supported. Apple has no clue where the Canon submission may be in the pipeline, nor are they even able to find out. There is no timetable for Apple support. "It will come through on Software Update when it is available" says Apple. In the meantime, the quality of the printer is excellent to me....but for its lack of Mountain Lion support to me as a consumer.
....the SOLUTION (at least for me) is as follows. After downloading the drivers, proceed to the System preference>Print & Scan>+ (to add this printer)>select IP>enter IP address of the Canon>choose LPD>Leave Queue empty>Name Canon 4700 and use the Canon 4700 series. Now here is the critical step: go back to the print& scan window. Mountain Lion defaults to not sharing the printer. Select share this printer on network. Turn on Printer and Scanner sharing checkboxes. In the Printers window click the box next to the Canon. Click on "everyone". THIS DEFAULTS TO NO ACCESS...THUS I BELIEVE THE REASON FOR FILTER FAILED. Click to up/down arrow and select can print. That should be it.
I am no big computer whiz....but this worked!
