The present invention provides a pressure adjusting structure for printing head. A first pressure plate is disposed on a circuit board. Two elastic members are disposed on the first pressure plate. One end of the two elastic members provides downward force, respectively; the other end thereof is against a second pressure plate, respectively. An adjusting member passes through the second pressure plate. One end of the adjusting member is projective to the second pressure plate such that a user can adjust the downward pressure of the first pressure plate. By ensuring the pressure value within the optimum pressure range, the superior printing quality can be achieved.
