Abstract
A printer for negotiating transactions at the point of sale in retail establishments. The POS printer includes a selective check reading mechanism that converts the receipt printer into a check reader. The mechanism includes a magnet to magnetize magnetic characters on a check and a read head to read and analyze the signal waveform from each character. The check is pressed up against the read head and the magnetic characters are read only after the printing carriage of the receipt printer has moved to a dead zone within the printer housing. In the dead zone, a tab, riding on the printing carriage, releases a spring-biased pivot arm. The pivot arm becomes free to pivot, thus releasing a spring-biased plunger, the face of which, in turn, forces the check and its indicia against the read head.
