Wireless printing failure...

I have an old MBP running OSX 10.6.8. Using a Canon MX870. Previously was able to print wirelessly from my MBP and iPhone flawlessly. The last few months it has been more and more unstable to the point that now I can't print wirelessly at all. Prints fine when plugged into the usb port.

I recently changed the firmware on my Time Capsule and got some improvements in overall stability and reliablitiy with wifi. Hoped this issue would get better but no such luck.

I have removed all printers, changed the network, added the printer to the network, added the printer to the MBP. Then when I print it acts like it will work. The computer says it is printing. The printer screen says it is printing. It does that for about a minute, maybe two, then I get this:

That's basically what it has done all along since it started failing.

Thanks in advance for any assistance.
