摘要： This invention is directed to reducing power consumption even when there is a great amount of power consumed by a root complex in a printing apparatus (2) that employs a PCI Express architecture. To accomplish this, a printing apparatus (2) that includes a controller (105) capable of switching between a root complex and an endpoint and an accelerator controller (101) serving as a root complex performs the following processing. More specifically, in the power saving mode, the power source of the accelerator controller (101) is turned off and the controller (105) is set as a root complex. Power consumption in the power saving mode can be greatly reduced, and a return sequence from the power saving mode can be executed.
摘要翻译：本发明涉及即使当采用PCI Express架构的打印设备（2）中的根复合体消耗大量功率时，也降低功耗。为了实现这一点，包括能够在根部复合体和端点之间切换的控制器（105）的打印装置（2）和用作根复合体的加速器控制器（101）执行以下处理。更具体地，在省电模式下，加速器控制器（101）的电源被关闭，并且控制器（105）被设置为根复合体。可以大大减少省电模式下的功耗，并且可以执行从省电模式的返回顺序。

摘要： A method of instantly measuring the amount of ink discharged from a nozzle. The method of measuring the amount of discharged ink includes: a line pattern forming step of forming a line pattern by discharging ink from an ink-jet printhead; a first image-sensing step of sensing the line pattern by an image sensing device; a second image-sensing step of sensing a portion other than the line pattern by the image sensing device; a density calculating step of calculating density of each pixel of the line pattern by dividing the luminance value of the portion sensed in said second image-sensing step by the luminance value of the line pattern sensed in said first image-sensing step and calculating a common logarithm; an integrating step of integrating the density of each pixel of the entire line pattern calculated in said density calculating step; and an ink-discharge-amount determining step of obtaining the amount of discharged ink on the basis of the integrated density calculated in said integrating step.
