PURPOSE:To add the data relating to filter processing even to the data sent from a general machinery if desired, by discriminating whether control data is the data indicating the execution of filter processing to an addition means in accordance with the discrimination result. CONSTITUTION:When a control order is sent to an interface 1 from external machinery, the control order is temporarily stored in a buffer memory 2. When a CPU 3 reads the content of the buffer memory 2, the CPU 3 confirms that the content stored in the buffer memory 2 is an order word indicating filter processing referred to as list mode. Next, when the CPU 3 indicates heading printing from the content of a cord of film name and confirms a heading name, the CPU 3 performs the heading printing to the first line of recording paper prior to usual printing and counts up a counter for counting the number of printing lines. When filter processing is performed, a flag to the effect that each filter processing is performed to the internal register of the CPU 3 is erected to easily judge whether the filter processing is performed to printing data. |
