Abstract
A CRT controller can be included in a device for driving a dot array recorder. Image processed data output by the CRT controller is stored in a buffer memory. This data stored in the buffer memory is shifted by one raster in response to a vertical sync signal from the CRT controller. The period of the vertical sync signal is set through a command input device to correspond to the paper feed speed and the printing line density. A data display timing signal is output by the CRT controller to a data holding circuit. The raster of data shifted out of the buffer memory is held by the holding circuit and printed on a recording surface by a recording head.
