    摘要： A printer control system which enables the using applica­tion program to automatically selectively alter printer default parameters, to automatically selectively delete previously downloaded fonts and macros, and to enable the printer to operate from one of several datastream formats. The system allows the printer to initialize default param­eters for a succeeding job during the printing of a cur­rent job as long as the datastream format is unchanged, and allows the deletion of downloaded fonts as long as they are not needed for the current or future pages being printed for the current job.

    摘要： A page printer which rasterizes a page utilizing partial page bit map swaths. Received data to be printed is stored in packets (12-17) in a page buffer in random access memory. Data within each packet is arranged in printing order down the page to be printed, but the pack­ets themselves are arranged in the order received, and are not indexed or linked. As each swath (11) is rasterized, each packet is examined, and packets containing data falling at least in part within the active swath are processed. The printer is controlled by a programmed microprocessor, and logic hardware assistance is provided for translating data addresses from logical addresses to physical addresses. Logic hardware assistance is also provided for making the determination of whether or not a given data address lies within the active swath.

    摘要翻译： 页面打印机利用局部页面位图条幅栅格化页面。 接收到的要打印的数据以数据包（12-17）的形式存储在随机存取存储器的页面缓冲区中。 每个数据包内的数据按打印顺序排列在要打印的页面下，但数据包本身按收到的顺序排列，并且未被索引或链接。 当每个扫描条（11）被光栅化时，检查每个分组，并处理包含至少部分落在活动扫描条内的数据的分组。 打印机由编程的微处理器控制，并提供逻辑硬件辅助，用于将数据地址从逻辑地址转换为物理地址。 还提供逻辑硬件帮助，用于确定给定数据地址是否位于活动行区域内。

    摘要： A memory management system for a page printer controller (11) which includes random access memory (17) allocated among bit map memory (30), page buffer memory (29), and user memory (28). The memory management system allocates the random access memory to provide either a large bit map memory or, responsive to needs of the controller (11) for increased memory for other uses, for allocating the random access memory (17) to provide a small bit map memory and place more memory in the page buffer memory (29) and user memory (28).
