Abstract: A distinctive code for each character that appears on the type train of a printer is stored in a train image field. At the time of loading this field an associative bit is stored at a particular address in an associative field, the address being identifiable with the numerical value of the bits in the code for each character. When characters to be printed are loaded into the print line buffer of the printer, the address for the associative bit is accessed directly from the print line buffer data register and the presence of the bit identifies the character as having a matching code in the train image field.

Abstract: A system and method for automatically compensating for inaccuracies in the positioning of the timing mark sensor of a band line printer. A selected hammer (12) is operated to impact a test characters and an adjacent space between characters or a space provided by a blank character on the type band (10). The flight times of the hammer (12) for the character (11) and space impacts are measured under control of a microprocessor (30) programmed to locate the edge of the test character and to compute a timing adjustment value for use by the printer control to obtain centered impacts of characters during printing.
