A printing system includes a print station for receiving print medium traveling along a transport pathway and an adjustable print head assembly. A medium dispenser transports the print medium on the transport pathway to the print station, and a medium width sensor detects the width of the print medium. A pressure sensor arrangement detects pressure imposed by the print head assembly at points along the width of the transport pathway when an image is printed on the print medium. A monitoring subsystem in communication with the medium width sensor and the pressure sensor arrangement calculates, based upon the detected width and the detected pressure, amounts of pressure imposed by the print head assembly along the width of the print medium.

A printer comprising a printhead configured to selectively cause a mark to be created on a substrate. The printer comprises in a stepper motor having an output shaft coupled to the printhead, the stepper motor being arranged to vary the position of the printhead relative to a printing surface against which printing is carried out, and to control the pressure exerted by the printhead on the printing surface. The printer further comprises a sensor configured to generate a signal indicative of an angular position of the output shaft of the stepper motor. The printer further comprises a controller arranged to generate control signals for the stepper motor so as to cause a predetermined torque to be generated by the stepper motor; said control signals being at least partially based upon an output of said sensor.

A thermosensitive printing device includes a print roller, a printhead module, a printhead pressure adjusting mechanism and a casing. The printhead pressure adjusting mechanism is supported by the casing. When a print medium is transferred through a region between the printhead module and the print roller, the print medium is printed by the printhead module. The printhead pressure adjusting mechanism is located over the printhead module and contacted with the printhead At least a portion of the printhead pressure adjusting mechanism is penetrated through the casing groove and movable within the casing groove according to a width of the print medium. The printhead pressure adjusting mechanism includes an adjusting knob and an identification pattern. When an adjusting knob is rotated, a pressure of the printhead pressure adjusting mechanism applied to the printhead module is adjusted and the pressure is recognized according to the identification pattern.

A recording-head position adjustment mechanism includes a beam to suspend a recording head that discharges droplets so that the recording head is drawable out in a predetermined direction; a first supporter disposed at one end of the beam in the predetermined direction and having a support shaft to support the beam; a second supporter disposed at another end of the beam in the predetermined direction with the beam interposed between the first supporter and the second supporter. The second supporter is attached with an adjuster via which the second supporter supports the beam. The adjuster includes a coarse-adjustment shaft member and a fine-adjustment shaft member that are manually rotatable independent of each other. The coarse-adjustment shaft member coarsely adjusts a rotation angle of the beam at which the beam rotates around the support shaft by manual rotation. The fine-adjustment shaft member finely adjusts the rotation angle of the beam.
