I have a Canon (or Epson) printer and use Ubuntu 12.04. It looks like my printer has partially stopped working after a recent update -- only half of the last page is printed out (sometimes this happens with all pages).

This problem was a known bug with Ubuntu's printing subsystem (CUPS), introduced by a recent update towards the end of July.
It has now been fixed (as of August 7, 2012).
The fixed version should be installed as part of your regular Update Manager process within the next few days; if you would like to fix it now, please do the following:
