ABSTRACT:
A mechanism is disclosed for automatically positioning the print mechanism with respect to the forms and ribbon in a printer assembly. The automatic adjustment takes place for varying thicknesses of the forms, which is a function of the number of copies being printed and the type of form, as well as the variations in the thickness of the ribbon. The above-mentioned adjustment takes place after there has been a simulation of the print hammer striking the paper which may be a single-part or multi-part form.
