METHODS AND APPARATUSES FOR CONTROL OF A SIGNAL IN A PRINTING APPARATUS

摘要

A printing apparatus (10) and related methods are provided that precisely control the transition of an electrical signal that causes a printing substance to be deposited In particular, in some embodiments, a circuit (39) is configured to control the application of a firi pulse to a printing element (84), and the ppnting element is configured to control the application of a printing substance The circuit i this embodiment is configured to condition or control the transition of the firing pulse from the first state to the second state such that current through the printing element dissipates to zero over a period of time that neither too fast nor too slow.
