Recording head control method and dot impact printer

摘要

A recording head control method prevents head coil burnout caused by heat output while suppressing a drop in printer throughput. A control method for a recording head 18 of a dot impact printer 100 that prints information on a recording medium S by driving the recording wires 9 of a recording head 18 that has a plurality of recording wires 9 while a carriage 19 that carries the recording head 18 traverses the recording medium S, each of the recording wires 9 being allocated to printing one dot line in the scanning direction of the carriage 19, the control method including steps of: during dot line printing, determining before printing if the number of previously defined specific dot patterns P1, P2 contained in the dot line to be printed is greater than or equal to a reference number N of 2 or more; and printing the dot line based on the result of the decision.

1. A control method for a recording head of a dot impact printer that prints information on a recording medium by driving recording wires of a recording head that has a plurality of recording wires while a carriage that carries the recording head traverses the recording medium, each of the recording wires being allocated to printing one dot line in the scanning direction of the carriage, the control method comprising steps of:
during dot line printing:
setting a predetermined number of pattern detection areas of a specified width within the maximum line length of the dot line;determining before printing if a pattern detection area in the dot line to be printed is a specific area containing previously defined specific dot patterns;determining if a number of specific areas containing previously defined specific dot patterns in the dot line is greater than or equal to a reference number of 2 or more; andprinting the dot line based on the result of the decision.
