PURPOSE:To obtain normal printing by returning the content of a receiving buffer memory to the past to print and investigate the same, in a printer apparatus having the receiving buffer memory for storing data, by mounting a forcible printing stopping means using the operation of a control panel, a means for returning an address loading the data of the receiving buffer memory to an arbitrary position and a means for operating the control panel to forcibly perform an arbitrary command and again performing printing according to received data. CONSTITUTION:A program memory 6 is which a control program operating a central processing unit 3 has been written and a control panel 9 performing key input to execute a command are provided and, when the forcible stoppage of printing is inputted via the key of the control panel 6, a printer stops printing. When the alteration of the load address of receiving data is inputted, the load address of the receiving data written in a work memory 7 is returned by the number of key input bytes and the cause of faulty printing is easily investigated by printing the past hystory and the command is forcibly executed to enable normal printing. |
