Abstract

A printer, which enables complicated printhead controls without a complicated logic circuit, includes a data table showing a control pattern of six controls stored in a RAM. When a drive trigger is inputted into a read-trigger generator, an address generator generates the address of the data table in the RAM as an address signal and inputs the address signal into the RAM. On the other hand, the read-trigger generator inputs a data-read trigger into the RAM. Control signals read by these signals are inputted into a head driver with heat pulses, which drives the printhead.
