Abstract

PURPOSE:To enable an operator to select a low-noise printing, as necessary, by a method wherein a printing speed can be changed over by a switch. CONSTITUTION:A control part 2 selects a normal printing speed 3 and a low- noise printing speed 4 using a switch 1 and issues a control instruction. Namely, by making a printing speed selectable by the change-over of the switch, the need for changing an existing program is eliminated, and an operator can accordingly and selectively change the printing speed regardless of before or during printing, as necessary. Alternatively, the printing speed can be changed over stepwise in several steps, as necessary.
