摘要:
A printing apparatus is 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 is configured to control the application of a firing pulse to a printing element, and the printing element is configured to control the application of a printing substance. The circuit in 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 tine that is neither too fast nor too slow.
