Claims

[Scope of utility model registration request]

The printer includes two printer heads that each operate in response to independent timing signals, one CPU that drives and controls the two printer heads, and printer drive means that operates in response to a timing signal from each of the printer heads, the CPU The data necessary for processing the next timing signal is stored in advance in the printer head, the stored data is processed in each of the printer heads, and the print operation of each printer head is executed with the next timing signal enabled to be received. A printer control device characterized by:
