The print module comprises a feltlike material 1 storing ink supplied to cartridge 2 by capillary effect. The ink is made conductive by adding a suitable electrolyte. Electrodes 3 and 4 are fixed to material 1. Electrical contact to a measuring circuit in the plotter is established by a gripper arm (not shown). The measuring circuit serves to measure the dampness of material 1 as a function of its electric resistance.
