Abstract
In a data link control method, a receiver and a transmitter are connected so that the transmitter can transmit every line of a predetermined data at a first speed, the receiver plotting every line of the predetermined data on a recording paper thereof at a second speed. A predetermined mode is selected from either a buffer mode or a skip mode on the basis of a ratio of the first speed to the second speed and whether a buffer can be used by the receiver. The predetermined data is temporarily stored in the buffer and then plotted during the buffer mode. The recording paper of the receiver is fed at a third speed higher than a normal speed when a blank line of the predetermined data is plotted thereon during the buffer mode and skip mode. A data amount of the blank line being reduced to a ratio of the normal speed of the recording paper to the third speed thereof and a fill-bit representing 0 being added to the data amount of the blank line reduced during the skip mode so that the transmitting operation of the transmitter can be synchronized with the plotting operation of the receiver.
