用于控制喷墨笔的系统和方法
摘要：
提供一种控制电路(602)用于使用在该控制电路与具有不同数目的内部选择线的喷墨笔(602，604)之间延伸且被喷墨笔共享的外部选择线(618)控制所述喷墨笔。在一个实施例中，控制电路包括：存储值的寄存器(622)，所述值指示关于每个外部选择线是否要发送脉冲；第一控制模块(702)，配置为在查阅所述寄存器之后控制在第一外部选择线上发送的选择脉冲；以及第二控制模块(704)，配置为在查阅所述寄存器之后控制在第二外部选择线上发送的选择脉冲。
摘要（英）：

A control circuit (602) is provided for controlling ink jet pens (602, 604) having different numbers of internal select lines using external select lines (618) that extend between the control circuit and the ink jet pens and that are shared by the ink jet pens. In one embodiment, the control circuit includes a register (622) that store values, the values indicating whether a pulse is or is not tobe sent as to each of the external select lines, a first control module (702) configured to control select pulses sent on a first external select line after consultation of the register, and a secondcontrol module (704) configured to control select pulses sent on a second external select line after consultation of the register.
