Abstract
The printer comprises a ROM recorded for each character with a set of pairs of numerical instructions, of which one represents the direction of a constant velocity vector of the tracing element for tracing a segment of the character, and the other represents the duration for which that velocity has to be applied to said element. The direction instruction is decoded by a decoder in order to generate two orthogonal components which control two servo-mechanism by way of two corresponding D/A converters. The duration of the movement is controlled by a counter loaded by the duration instruction and decremented by a clock signal. Every time the counter is emptied a logic unit responds by addressing the next byte in the ROM.
