Not sure if I have the skills to replace it - will figure it out - looks like I just unscrew the old printhead unit and switch in the new one - the only connection seems to be the 9 pin ribbon cable.

If anybody has done this before I'd appreciate any tips!

There are five wires soldered to the small circuit board (on the left hand side in your picture).
They lead to a connector in the center of the main circuit board. These will have to be moved to the new print head. One is red and four are black. I moved them one at a time so I would not get the black ones mixed up.
These control the motor for the paper advance and the print head position.
