ABSTRACT:
User adjustment of an automatically established gap between a print head and a platen allows adjustment of print head gap relative to a set point by a simple key actuation operation which is preferably conducted during printing operation so that the user can directly observe the result of the adjustment. Storage of user defined adjustment values in non-volatile memory are correlated with measured thicknesses or tolerance ranges thereof and can be recalled after power off/power on cycles and/or after change of paper stocks in the printer. Adjustment limits are imposed to prevent printer damage and user adjustment can be carried out at higher resolution than automatic head gap setting. Graphical and fixed legend displays are preferably provided for confirmation of the adjustment and informing the operator of limits and operating limits and conditions of the gap adjustment.
