Bank checks 10 are normally printed with a machine-readable version of the check amount in magnetic ink characters 11. To assist automatic processing of the checks, this number often contains a series of leading 0's 12, and is required to contain field mark 13. The speed at which checks can be processed may be limited by the speed of a serial printer 14 for printing the characters 11. This speed can be increased by adding supplemental type faces 15 and 16, respectively, providing the 0 and field mark characters. Individual hammers 17 and 18 are respectively associated with the type faces 15 and 16. As a bank check 10 is stepped past print hammer 19 of the main printer 14, print wheel 20 is positioned by control circuitry 21 to present individual characters for printing.
