Abstract
A plurality of printing needles forming an array are mounted in a printing head and are periodically driven to impact a printing ribbon onto a recording medium. The printing head contains a brake for each needle so that selected needles can be prevented from striking the printing ribbon allowing the formation of a desired character matrix pattern on the recording medium. Each brake may be driven by a piezoelectric element.
