    • An information processing apparatus serves as a host unit for communicating with a plurality of printing apparatuses via a network. Each of the plurality of printing apparatuses is in a print-ready state or a second power state, in which power consumption is less than that of the print-ready state. The information processing apparatus includes a request unit adapted to request status information of each of the plurality of printing apparatuses, a reception unit adapted to receive the status information of each of the plurality of printing apparatuses requested by the request unit, an identifying unit for identifying each of the plurality of printing apparatuses as being either in the print-ready state or the second power state, based on the status information received by the reception unit, and a user interface unit adapted to control a display of a plurality of printer states. The display indicates the state of each of the plurality of printing apparatuses on a same window, so as to indicate each printing apparatus as being in the print-ready state or in the second power state, based on a respective identification result of the identifying unit.
    • 信息处理装置用作通过网络与多个打印装置通信的主机单元。 多个打印装置中的每一个都处于打印就绪状态或功耗小于打印就绪状态的功率状态。 所述信息处理装置包括:请求单元,其适于请求所述多个打印装置中的每一个的状态信息;接收单元,适于接收由所述请求单元请求的所述多个打印装置中的每一个的状态信息;识别单元,用于识别 基于由接收单元接收的状态信息,多个打印设备中的每一个处于打印就绪状态或第二电源状态,以及适于控制多个打印机状态的显示的用户界面单元。 显示器指示在同一窗口上的多个打印设备中的每一个的状态,以便基于识别单元的相应识别结果来指示每个打印设备处于打印就绪状态或处于第二功率状态 。

    • An arrangement for printing a print image having regions of different print image resolution onto a moving postal item in a mail processing device has a microprocessor, a pixel memory, a read-only memory and a print data controller for pixel data editing while printing with a printhead. The microprocessor is programmed to operate from data in the read-only memory, a number of data strings having a switchable number of data words and to store them in the pixel memory. A maximum number of data words per data string is downwardly transgressed when the pixel data are stored compressed. The print data controller undertakes pixel data editing while printing with the printhead and is equipped to decompress the compressed pixel data per data string and to supplement the pixel data missing due to the compression such that the reduction of the number of data words per data string corresponds to the reduction in the resolution during printing. The microprocessor is programmed to supply at least one parameter for the control of the resolution to the print data controller, and the print data controller correspondingly switches the resolution that can be achieved in printing.
    • 用于将具有不同打印图像分辨率的区域的打印图像打印到邮件处理设备中的移动邮件上的布置具有微处理器,像素存储器,只读存储器和用于像素数据编辑的打印数据控制器,同时以 打印头。 微处理器被编程为从只读存储器中的数据操作,多个数据串具有可切换数量的数据字,并将其存储在像素存储器中。 当数据被压缩存储时,每个数据串的最大数量的数据字被向下跨越。 打印数据控制器在用打印头进行打印时进行像素数据编辑,并且被配置为对每个数据串进行压缩像素数据的解压缩,并补充由于压缩而丢失的像素数据,使得每个数据串的数据字数减少对应 降低打印时的分辨率。 微处理器被编程为向打印数据控制器提供至少一个用于分辨率控制的参数,并且打印数据控制器相应地切换在打印中可以实现的分辨率。
