A point-to-multipoint communication system that is well operative for transmitting megabytes of information in the form of a signal burst. Each slave unit temporarily stores a signal and measures the amount of the signal information before transmitting the signal. A master unit requests that slave units report the measured amounts of information, and they give reports to the master unit. On the basis of the reports from the slave units, the master unit determines an allowable amount of information for each slave unit and permits the slave units to transmit the stored signals according to the request from the master unit. The interval between the reports from the slave units to the master unit can be varied.

A thermal head comprises a plurality of parallelogrammatic resistors for generating heat formed on an insulated substrate made of, such as ceramics or alumina. The resistors are aligned at regular intervals, and one pair of opposite sides of each resistor are connected individually to lead electrodes. These opposite sides are equal to or longer than the other opposite sides, and an acute angle formed between each two intersecting sides is 45.degree. or less. The resistor is heated by various electric currents to record printing dots of various sizes.
