Movement of the stylus nib or application of more than a predetermined compressive force to the stylus nib turns on the on/off switch and so causes the marking device to be turned on, so marking a path on the surface.

A cartridge for a pen, the cartridge including:
- a cartridge body;
- a marking device operative to mark a visible path onto a surface, the marking device being electronically controllable to change the value of at least one attribute of the path;
- a non marking stylus nib, and
- an on/off switch and wherein the on/off switch is turned to an “on” state upon sensing of more than a predetermined amount of movement of the stylus nib or application of more than a predetermined compressive force to the stylus nib, and wherein the marking device includes a printhead and a capping device movable between an open position, in which the printhead may deposit ink on the surface, and a closed position, in which the capping device blocks the printhead from depositing ink.
