PURPOSE:To enable to perform printing by a method wherein, when expression of data is required to be displayed specially in a graphical representation. A specified key is set and printing is performed using the input of said key thereby enhancing the density in printing. CONSTITUTION:When a print-mode SW1 of a keyboard KB is changed from the normal mode into a graph-mode, a control section detects through a signal line ls that the print-mode has been changed to the graphic-print and switches a function key located on the keyboard KB to a graph data input key. The graph print is composed of assembled dots, including 126 dots in the horizontal direction and 7 dots in the vertical direction. Print memories PCM1 and PCM2 are provided with a memory capacity of 126 bytes in which 1X7 dot data were allocated to one single byte and for execution of reciprocating printing functions, forward printing memory PCM1 and backward printing memory PCM2 are allocated, by which a graph print with an elevated density becomes available. |
