Abstract:
A resolution control apparatus for a printer, comprising:a carriage attached to and traveling along a guide shaft mounted inside said printer, said carriage bearing a plurality of discrete indicies each representative of a different orientation of said carriage relative to a direction of conveyance of a medium to be printed with images by said printer during said conveyance;a printer head mounted in said carriage, said printer head having a rear side mounted adjacent to said guide shaft;angle control means for incrementally adjusting the position of said carriage to change an installation angle of an array of elements carried by said printer head to form the images while said carriage reciprocatingly conveys said printer head along a path of travel traversing a width of the medium, with said installation angle being measured between a linear dimension defined by said array and a path traversed by the medium through said printer;means tor indexing said installation angle; andsensing means operationally responsive to said indicies, for detecting said installation angle of the printer head by detecting from among said indicies one of said plurality corresponding to said orientation and generating a print control signal corresponding to said installation angle.
