ABSTRACT:
A specialized peripheral controller for controlling data transfers between a main host computer and a train printer mechanism is provided with a peripheral control interface circuit to control and monitor the printing of data and the paper format for the train printer mechanism. The peripheral control interface circuit includes a printer column timing pulse generator for enabling the train printer mechanism to scan over each column of its available printing area at least twice during each revolution of a train module which carries graphic character sets that will imprint upon the paper train when struck by a print-hammer within the train printer. The peripheral control interface circuit also includes control means to start and stop the motor of the train printer, means to select whether output data signals are for printout selection or for paper format control, and means to receive and sense condition information signals from the train printer mechanism.
