Can't print emails...

Hi there

For some reason my Canon IP4700 has decided to stop properly printing emails from my MBP (with latest mountain lion).

The printer itself works ok...it prints test pages not problem. It also prints PDFs without a hitch, and photos. However when I try and print an email (or note) it prints the header info and then absolutely nothing else.

I've cleaned the printer head, checked the ink tanks and downloaded the latest driver. Still no joy...

Can anyone help?!

thanks

Steve
