Printer problem

[LL-user]

Hi Jim,

To uninstall the driver:

Code:

sudo apt-get purge cnijfilter-cnijfilter-mg500series

To remove the ppa and update the package index files:

Code:

sudo add-apt-repository -r ppa:michael-gruz/canon

Code:

sudo apt-get update

To remove the gpg key (not really necessary, but to keep it clean):
1. get the key ID by searching for the entry in the list you get via:

Code:

apt-key list

You will find something like this: pub  1024R/EEA14886
- 1024 is the keylength
- EEA14886 is the ID

2. delete the key:

Code:

sudo apt-key del <ID>

Hope that helps!
