Updated to 10,11 and did NOT auto install Printers connected

It could be a permissions problem. To test if you are still a member of the admin group and in the sudoers file, try a simple command in a terminal window, but try to execute is as superuser:

sudo uname -r

Does it verify the password and print the specs, or do you get an error? If it prints out OK, please cut and paste the output here so we can see what release level you are at.

See if you can start it from the dash: press the super key and type "printing" in the search bar. Click on application if it finds it.

It could also be due to a problem with the upgrade, such as can happen if the dependencies get confused and something is removed that shouldn't be. Try the following commands in terminal: (all are benign and will only do routine operations or install applications if they are missing or otherwise required).

#reload the lists:
sudo apt-get update

#fix any partially installed packages:
sudo apt-get -f install

#install cups
sudo apt-get install cups

I don't know what the Gnome configuration module is called that is part of the "printing" setup. If anyone knows what it is called we could try re-installing that too. (it could be part of cups anyway)

Not quite so benign but you could try the following in a terminal. In the case of a failed or interrupted upgrade it will try to resolve all dependencies and finish the release upgrade. In addition to this, If the current release is not the latest stable release (11.10) , it will attempt to upgrade the system further. You should back up all important data before performing release upgrade operations (including "should have backed up" before doing the previous upgrade).

Ubuntu will not automatically install printers, however if they were previously installed then it should have upgraded them, however if you had drivers or other modules from a PPA then it would not have installed them, and it is recommended that you remove any Personal Package Archives (PPAs) from the sources list before you upgrade. Unresolved dependencies could have been one reason for the upgrade to remove functionality instead of just upgrading it.

Oops, forgot the last command, to upgrade the release. Not this is _not_ a benign command and you should back up your important data before doing this. It will try to upgrade to the next release, or will restart the upgrade if the latest upgrade was interrupted for some reason:

sudo apt-get dist-upgrade
