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.
