Thermal print head with a thermal print substrate on which are arranged a plurality of print resistors (R1-R416) which are adapted for selective electric heating, for generating of a dot pattern on a paper web which is in contact with the print resistors. Each resistor is provided with a control unit (B1-B32) included in the print head. The control units comprise members for storage of information (DATA) which is supplied to the print head and which defines the selected resistors. A control pulse (STR) is supplied to the print head for activation of the selected resistors. The control units comprise delay members (Hi) for successive delay of the control pulses which are supplied to the control units of the different resistors, thus obtaining stepwise switching on and off of the print resistors. |
