Abstract
In an electronic control system for controlling the printing speed of a fast dot-matrix printer writing column by column, which uses a data input signal coded in a permutation code, a storage register (59) with a storage capacity of at least three codewords for storing the input data and a point clock oscillator (60) are provided. The control system exhibits a print clock generator (62) with a plurality of counting-down circuits, connected to the oscillator (60), for generating a signal for normal print speed and a signal for a fast print speed and the print clock generator (62) can also generate a variable clock signal in which the initial column intervals are longer than in the signal for normal print speed and the subsequent column intervals are preferably shorter than in the signal for normal print speed. A print clock control unit (61) selects one of these print speed signals for controlling the print speed in each print cycle, in dependence on the printer state in the preceding cycle, the variable signal is used whenever the write head has stopped during a particular time interval. <IMAGE>
