Canon MX870 couldn't print after Mt. Lion installed

Question

After installing Mountain Lion, my printer, Canon MX870 stopped printing with error message "Stopped - "Filter" Failed." 
I downloaded the newest drivers from Canon, but it still didn't work. I spent over 30 mins with Canon's tech support, went through deleting printer from System preference "printer & scanner" list, disconnect printer, "resetting printing system," rebooting computer, then reconnecting printer, adding printer on "printer & Scanner" list again..... still didn't work. Canon tech support suggested to contact Apple, so I got Apple support help. Basically, we went through exactly same steps over and over,... didn't work. Then, I was suggested to use disk utility to verify disk, repair disk permission... restart and do above steps again, still didn't work. Next apple care guy suggested to "reinstall Mountain Lion" all together. I did. Still didn't work. He looked into communities comments and suggested to download 3rd party printer drive..... ahhhh, you are getting paid to support customers with your professional knowledge. Just looking up some solutions in the community posts and if it could solve the problem, I had already done so and didn't need to set up phone supports.   I was this close to give up....
As the last resort, I decided to manually delete all Canon folders from Library and application folder, restart computer, then installed new drivers again. Guess what, it worked.
So, if any of you having the same issues as I had, I recommend you to MANUALLY DELETE printer files. Evidently, "deleting printer" or "resetting printing system" via System preference don't delete all the existing Canon printer folders. (I wonder why AppleCare guys never suggested to do this....it could save me many hours.)

Hi Pahu. I've read some of your answers to other Canon printer owners and they've helped those people, so hopefully you can help me out. I tried both a regular cleaning and deep cleaning as well as a nozzle test, but that didn't fix the printing issue. Same goes for a factory reset on the actual printer.
So did the black ink appear with the nozzle test? If it did, then the black head/tank are okay.

The only thing I think could be causing this specific printer issue is possibly the chip on the ink cartridges. They aren't authentic Canon ink cartriges, but they worked before (however, on my PC). I purchased the ink cartridges a few years ago (2006 to be exact), so it is possible that the chip is interfering with the printer being fully printing all documents?
If the nozzle test does show the black ink then it won't be an issue with the cartridges.
But if there is no black on the nozzle test, and the deep clean has not helped, then you may just need to purchase a new black cartridge. With you purchasing the cartridges in 2006 and having the printer stored for a period of time, then it is quite likely that the nozzles in the print head have dried up and stopping the ink flow.

I'm kind of annoyed with myself that I didn't use this printer prior to upgrading from Snow Leopard to Lion to Mountain Lion since part of me thinks that the printer could be incompatible with Mountain Lion, but then again, I'm not a Mac expert. I'm computer/tech savvy, so any other suggestions you think may help (however "technical" it may be) would be much appreciated!
The printer is compatible with Mountain Lion. If it wasn't, then it would not print at all.
The other thing to note is that you have the same issue with your Windows partition via Bootcamp. If Windows was still printing but Mtn Lion wasn't, then there would be cause to blame the new version of OS X. But from what I have read it appears to be a physical machine issue rather than the OS.
