Abstract
An inkjet printing system includes an electronic controller including electronics providing first signals having first signaling levels, and low voltage differential signaling (LVDS) drivers which receive the first signals and convert the first signals to second signals having LVDS levels. Cabling is coupled to the LVDS drivers and carries the second signals to an inkjet printhead assembly. The inkjet printhead assembly includes LVDS receivers coupled to the cabling and receiving the second signals and converting the second signals to third signals having third signaling levels.
