I've recently upgraded my Mac to one running Lion 10.7.2.


My Canon PIXMA MP780 no longer works. The icon is sitting in the dock with a no-entry sign through it.


I've downloaded new software and drivers for it, restarted, deleted and re-added the printer via System Preferences, and am really not sure what to do next...


Have emailed Canon who can take up to 5 days to respond.  I'd like to do some printing before that if I possibly can.


One thing I wasn't able to do that Apple recommend here: http://support.apple.com/kb/TS3147 is to reset the printing system.  The dialogue box they refer to doesn't contain the 'reset printing system' option they refer to here: http://docs.info.apple.com/article.html?path=Mac/10.6/en/14001.html


Would be most grateful if anyone has experience of this or knows of a fix.


Many thanks!



iMac, Mac OS X (10.7.2)

    I've just run into the same complication as you did.  My Pixma MP780 no longer works since I upgraded to Lion 10.7.2.  Canon USA doesn't list any drivers available.


    Were you ever able to resolve the issue?  I would greatly appreciate any advice/insight you might have on the matter.


    Thank you,

    I have the same problem!  I upgraded software and the Canon MX780 printer just went away.  Print & scan has the Canon MX870 series put only the scan options.  However, I can still print from a networked laptop.  Just like I always could.  Thinking of importing the laptop DMG and trying to install it.  Canon site has only a scanner driver.

    Apple support site tells me that Canon printer driver for MX870 is"

    Canon MX870 series10.51.2.0P


    Like I said I can print from a networked laptop.
