Abstract:

A descender printing system for a dot matrix printer, comprising a detector for detecting code words representative of descender characters (lower case letters, punctuation, fractions, etc. ) prior to printing, and shift means for actuating the line feed mechanism of the printer to advance the paper by two or more dot heights and thereby print the descender elements of such characters below the normal base line. The shift means again actuates the line feed mechanism to return the paper to its original position when the next non-descender character is to be printed.
