ABSTRACT:
In printing devices which are to print automatically readable script in particular great value is placed on an entirely accurate and clearly readable printing script because otherwise the reading devices recognize erroneous characters or the documents are rejected. In order to produce easily readable characters and in order to increase the life of the corresponding type wheels it is proposed either to move the document (8) by means of a step motor (SM) with micro-step control (MP, D/A.sub.1, D/A.sub.2, V.sub.1, V.sub.2) and to arrange the characters, which are to be arranged flush right or flush left, according to convention, in the center (FIG. 2A) and to bring about the flush right or flush left printing by means of the micro-step control. In addition, it is suggested, according to the invention, to also control spoke type wheels (1) with different pitches by means of a type wheel drive motor (M) provided with a micro-step control (MP, D/A.sub.1, D/A.sub.2, V.sub.1, V.sub.2).
