PRINTER DRIVER DEVICE PROVIDED WITH VIDEO SIGNAL OUTPUT DEVICE

PROBLEM TO BE SOLVED: To permit a great number of people to simultaneously view the whole face of printing paper which cannot be viewed unless it is printed by providing a video signal generation output means for generating a video display signal from an image data generated in a printer driver device and displaying a video. SOLUTION: When this printer driver device 4 receives a print output signal 3 from a computer device 1, it is stored in a DMA memory 6. Then, a processing that various control codes and print signals are separated is executed and they are converted into a program language and are stored in a RAM memory 7. Then, they are converted into picture image data and are stored in a picture image memory 8. In a video display signal generation circuit 12, the image data are converted into RGB being the three primary colors of light for video display based on the image data accumulated in the picture image memory 8 and mixed with vertical/horizontal synchronizing signals to generate the video display signal.
