Thermal printers |
摘要 |
Any element of a thermal print bar of resistive material is heated by a current pulse passed across the bar between an appropriate conductor pairing. Certain conductors are deposited in two parts with a rectifying layer deposited between the parts to provide diode isolation of heating paths from one another.
