A modular stylus assembly for printing on electrosensitive sheets includes, in combination, a print-head module having a first wall, a pair of spaced second walls extending from the first wall and defining a channel therebetween, and a multiplicity of stylus wires extending rectilinearly and in parallel alignment through the second walls and within the channel alongside the first wall, and a connector module receivable in the channel and includes a multiplicity of alternating electrically conductive and electrically insulating wafers respectively disposed in planes extending through the pair of spaced second walls, the electrically conductive wafers being spaced from one another by the electrically insulating wafers a distance corresponding substantially to the spacing between the parallel stylus wires whereby the electrically insulating wafers of a connector module received in the channel are respectively in electrically conductive engagement with the stylus wires, the connector module having means for selectively electrically energizing the electrically conductive wafers and the stylus wires.
