A printer control method includes the following steps: setting triggering conditions for executing functional items and for startup a configuration menu; executing a functional item if the key information had fulfilled the triggering condition for executing the functional item; and launching a configuration menu if the key information had fulfilled the triggering conditions for startup the configuration menu. By setting the triggering conditions for executing functional items and for startup a configuration menu, then determining whether the key information has fulfilled the triggering conditions for executing functional items and for startup a configuration menu, the printer directly executes the functional item as long as the key information has fulfilled the triggering condition for executing the functional item. When the printer is powered on, it skips the step of launching the configuration menu, operates conveniently and saves paper.
