Abstract:
A printer system comprising a printer controller and a printer connected by a bus, wherein said printer controller supplies said printer with image data via the bus and said printer prints an image, which is represented by the image data supplied from said printer controller, at a constant speed,said printer having a buffer memory possessing a fixed image-data storage capacity smaller than a quantity of image data representing one frame of the image, said buffer memory temporarily storing the image data supplied from said printer controller, either said printer or said printer controller being provided with a device generating a start signal which indicates start of supply of the image data, said printer controller comprising: an image-data transmission start controller for starting transmission of image data to said printer in packet units upon elapse of a predetermined period of time from generation of the start signal; and an image-data transmission controller for repeating, in packet units, the transmission of image data to said printer in such a manner that the image data that has been stored in said buffer memory is not emptied from said buffer memory, and said printer comprising a storage controller for receiving image data transmitted from said printer controller and storing the received image data in said buffer memory; and a printing controller for reading out the image data that has been stored in said buffer memory and printing the image, which is represented by the image data read out, at the constant speed.
