PURPOSE:To correctly output effectiveness/ineffectiveness of a data by outputting a discriminated result as to whether an inputted recording data is effective or ineffective at printing. CONSTITUTION:A recording data (receive data) stored in a receive buffer 4 is interpreted by a CPU 3, expanded to an image data and stored in a frame buffer 9a. In the process of this interpretation, it is determined whether each print command is effective or not. An effective command is stored in an effective command buffer 9b and an ineffective command is stored in an ineffective command buffer 9c. After printing is completed, by operating an effective command output switch 6 or an ineffective command output switch 7, contents of the effective command buffer 9b or the ineffective command buffer 9c are printed out and a dump list of the print command in which effective and ineffective are discriminated from each other can be obtained. |
