Explanation

Impact printers (dot matrix) form characters using a matrix of tiny pins that strike an ink ribbon against the paper. If some characters are incomplete-missing dots or strokes-but the printed output is still dark and legible where it does print, the most likely cause is that certain pins in the print head are stuck or clogged with debris, ink residue, or dust. Cleaning the print head clears the obstructions so all pins fire correctly. If the ribbon were worn out (C), the print would be uniformly faint, not selectively incomplete. Reinstalling drivers (A) or replacing the cable (D) would not cause mechanical, pin-level print omissions.
