The present application discloses an image transmission device and method. The image transmission device provided by the present application comprises: an FPGA configured to receive pixel data in image data from a video camera in sequence and buffer the pixel data into a memory, and determine, upon reception of a line of pixel data, a line number of the line of pixel data in the image data and a frame number of the image data; and a processor configured to obtain the line of pixel data, the line number of the line of pixel data and the frame number of the image data from the FPGA, package the obtained line of pixel data, line number of the line of pixel data and frame number of the image data into a data packet, and transmit the data packet to a server.

An image output system includes a terminal, a server, and a printing device that are communicable with each other via a network. The server includes: a storage device; and a CPU that executes a program for the server to function as a data generating portion configured to generate raster image data by executing a RIP process on the basis of print data received from the terminal and as a data transmitting portion configured to transmit data for outputting an image, to a destination that outputs the image. The data transmitting portion transmits, to the destination, the print data received from the terminal or the raster image data generated by the data generating portion, according to a kind of the destination.
