Abstract

An electrostatic matrix printer has a movable print head bearing a column of print needles selectively energised in response to binary coded electrical signals having a number of bits, equal to or less than the number of needles in the column. The binary signals, as well as determining the state of a group of consecutive needles in the column, to print different character columns, also include at least one further bit which determines the position of the said group in the column, enabling characters of different height and vertical position to be printed. <IMAGE>
