PURPOSE:To save paper and to expand a graph so that it can be readily seen, by controlling a paper feeding speed of a pulse motor, so that the lateral direction of the graph is expanded or contracted by the input operations of switches. CONSTITUTION:A switch SW1 for a keyboard KB, a print mode switch SW2, and a paper feeding pulse motor PM are provided in an electronic equipment with a printer, which performs the printing of a graph on roll paper P. The paper feeding speed of the pulse motor PM is controlled so that the lateral direction of the graph can be expanded or contracted by the operations of the switches SW1 and SW2. In this way, since the graph can be expanded or contracted readily in response to the types of the uses, the paper can be saved and the graph can be expanded so that it can be readily seen. |
