ABSTRACT:
Apparatus and a method for printer size reduction moves a carrier with print element through a carrier displacement field containing two acceleration ramp area subportions on opposite sides of a print line subportion. The acceleration ramp subportions are of different lengths. A first subportion permits acceleration of the print element to substantially all of a first lower print element speed. The second subportion permits acceleration of the print element to less than substantially all of a second higher print element speed. The overall field size is reduced, but functions effectively for uni-directional printing at the first (letter mode) speed and bi-directional printing at the second (draft mode) speed.
