    • In order to offer a printer capable of high throughput printing even when the same printing or printing that is partially different is repeated, the printing apparatus of present invention equipped with a storage unit for storing print image data based on print data received from the host device in a designated position and a printing controller and printer engine that performs print processing on the recording medium based on the print image data stored in the storage unit in accordance with control data received from the host device. Specifically, this printing apparatus features an erasure unit for selectively deleting print image data that has undergone the print processing from the storage unit in accordance with control data received from the host device. Also, the printing controller is preferably configured such that it performs the print processing in accordance with first and second types of control data, such that the erasure unit performs erasure processing in accordance with the first control data and does not perform erasure processing in accordance with the second control data.
    • 为了提供能够进行高通量打印的打印机,即使重复了部分不同的相同的打印或打印,本发明的打印装置配备有用于基于从主机设备接收的打印数据来存储打印图像数据的存储单元 在指定位置,以及打印控制器和打印机引擎,其根据从主机设备接收的控制数据,基于存储在存储单元中的打印图像数据对记录介质执行打印处理。 具体而言,该打印装置具有擦除单元,用于根据从主机设备接收到的控制数据,有选择地从存储单元中删除已进行了打印处理的打印图像数据。 此外,打印控制器优选地被配置为使得其根据第一和第二类型的控制数据执行打印处理,使得擦除单元根据第一控制数据执行擦除处理,并且不执行根据第一控制数据的擦除处理 第二控制数据。

    • A printer control device is employed with host computer controlled printers, typically of the point-of-sale (POS) type, which are capable of printing on several different types of recording paper. Several detectors are used on the printer to sense out-of-paper conditions with at least one detector being associated with each paper source used, and a detector selection device is used to determine which detector outputs are to be connected to the host computer through a communications interface. Detector output values can be stored and logically combined to allow transfer over a single communications line. Specific detector outputs can be enabled or selected for transfer to the host or for use in termination of printing operations. A paper type selector is used for setting line spacing or advancement amounts which are stored by the printer controller for later retrieval. Typically each advancement value relative to one type of paper is stored separately in a memory location or element. The type of recording paper and line advancement value for that paper are each selected by a printer control command, which is interpreted and acted upon by the printer controller. The printer controller responds to data printing commands and activates paper transfer mechanisms within the printer to achieve the established line advancement values during printing operations.
    • 与主机计算机控制的打印机(通常是销售点(POS))类型一起使用打印机控制装置,其能够在几种不同类型的记录纸上打印。 在打印机上使用几个检测器来感测纸外条件,其中至少一个检测器与所使用的每个纸源相关联,并且检测器选择装置用于确定哪些检测器输出将通过以下方式连接到主计算机: 通讯接口 检测器输出值可以存储和逻辑组合,以允许通过单个通信线路传输。 可以启用或选择特定的检测器输出以传输到主机或用于终止打印操作。 纸张类型选择器用于设置由打印机控制器存储以供稍后检索的行距或提前量。 通常,相对于一种类型的纸张的每个前进值分别存储在存储器位置或元件中。 纸张的类型和纸张进给值均由打印机控制命令选择,打印机控制命令被打印机控制器解释和操作。 打印机控制器响应数据打印命令并激活打印机内的纸张传送机构,以在打印操作期间实现已建立的行进位值。
