PURPOSE:To optimize the print control for lines, by receiving a video data on a plurality of lines in advance, converting and storing information representing the constitution of a screen, controlling the printer with the converted and stored information and printing data of the next and succeeding screens. CONSTITUTION:A video printer is constituted with a CRT display 1 outputting and sisplaying video data, a printer 2 and an editing circuit 15. A print enable signal is outputted to an AND circuit 14b of the circuit 15 with a print control circuit 4 of the printer 2, a vertical synchronizing pulse is transmitted to an FF6 via the display 1, the editing operation os started at the circuit 15, a horizontal synchronizing plulse counter 7, a write margin counter 9, a latch circuit 10 and a multiplexer 12 are operated, the video data are received and converted into the information representing the constitution of screen and stored in an RAM13. The printer 2 is controlled with the stored information and the data of the next and succeeding screens are printed. |
