I tried installing the driver by typing the following commands in the terminal:

sudo add-apt-repository ppa:michael-gruz/canon - the result was the following:

Then I typed: sudo apt-get update - the result was the following:

I typed the next command: sudo apt-get install cnijfilter-ip100series

The return response was:

Reading package lists... Done Building dependency tree
Reading state information... Done E: Unable to locate package cnijfilter-ip100series

Does anyone know the solution?
