发明名称 Printhead apparatus having digital delay elements and method therefor
摘要 Printhead and printer arrangements that provide digital delay between firing signals for a common firing interval. The delay achieves a controlled, staggered generation of firing signals that reduces EMI and instantaneous power supply draw and reduces or eliminates certain shielding requirements. Various arrangements are provided, including the use of edge triggered digital delay elements, staggered firing signal generation from firing signal control logic and the use of analog delay elements.
