PURPOSE:To increase a processing speed required for slip formation by suppressing accesses to a slip data storing external storage device to the minimum number of times. CONSTITUTION:A CPU 21 forms slip data based upon data successively keyed from a keyboard 12 in accordance with a slip format and temporarily stores the formed data in a RAM 24. When a cancel instruction is outputted, the CPU 21 corrects the contents of the RAM 24 in accordance with the cancel instruction. After determining slip data for one slip, a printer 16 prints out the slip and a floppy disk driver 25 writes and stores the contents of the RAM 24 in a floppy disk. |
