Abstract
The invention provides a drop-on-demand printer having a row of ink ejection locations for ejecting plural ink droplets, each ejection location having an associated ejection electrode for causing electrostatic ejection of the droplets from the respective ejection location. An intermediate electrode system has one or more rows of intermediate electrodesspaced from the ejection locations between the ejection locations and a substrate on to which the droplets are printed during use. Plural conductive tracksare provided, each corresponding to a respective intermediate or ejection electrodeand supplying a voltage to an electrode in use. Trackshave a resistive elementeither disposed immediately adjacent the corresponding electrode or actually forming the electrode
