Abstract
Printing of characters in non-impact manner by means of ink droplets which are driven through the nozzle of an inking device is optically sensed and the existence, the position, the size and the condition of each ink spot or mark are determined. The desired printing signals are generated and input in a signal shaping circuit and these signals are compared with the actual signals from the optical sensor and the ink droplet drive means is changed or altered to correct the printing.
