Abstract
A printer and method for negotiating transactions at the point of sale in retail establishments. The POS printer includes a check feeding mechanism that feeds a check into receipt printer with a face-up orientation. 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 MICR is read only after the printing carriage of the receipt printer has moved to a position outside the print zone, within the printer housing. In this position, a tab, riding on the printing carriage, releases a spring-biased pivot plug. The pivot plug 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.
