Besides printer ink being so expensive (what's wrong with the industry? is it unicorn blood?!?), I've never tried to install printer cartridges easier. You simply insert them into the socket, push with a finger and they snap into place. To turn it off, simply press the cartridge again with a finger. Yellow, cyan, magenta and black work the same way.
