摘要：
Inkjet printing systems and methods dynamically control meniscus pressure at a nozzle to more reliably deliver ink to a substrate. The systems and methods include inferring an angle of a longitudinal axis of a printhead relative to the vertical reference axis based on an orientation signal from an orientation sensor, determining a target feed fluid pressure upstream of the nozzle and a target recirculation fluid pressure downstream of the nozzle, thereby to maintain a target pressure differentiation across the nozzle based, at least in part, on the inferred angle of the longitudinal axis, and controlling a variable feed pump speed and a variable recirculation pump speed to obtain the target feed fluid pressure and the target recirculation fluid pressure.
