ABSTRACT:
An improved dry lettering printing machine of the type having a printing station, a rotatable disc or type font having embossed characters on the disc and a means for causing the machine to execute a print cycle which includes providing a color carrying ribbon and image carrying tape at the print station, precisely aligning a selected raised character on the disc for printing, exerting a printing force at the printing station, and reciprocating the tape cartridge to advance the tape and ribbon to print the next character at the printing station. The improvement includes an input keyboard for typing the information which is to appear on the tape interfaced with the printing machine with a programmed microcomputer which stores the input data and, with control signals, sequentially causes the printing machine to print a tape according to the information typed on the keyboard. The improvement further includes a means for electromechanically rotating the disc or type font in either a clockwise or counterclockwise direction, whichever is shorter, to position the next character for printing which enhances the speed and automatic operation of the improved machine. A number of function keys and indicators are also provided on the keyboard to further enhance the speed and ease of operation of the printing machine.
