    • A method for securing data in hardcopy documents. The method includes obtaining a page image having a private data item; generating an encrypted version of the private data item; obtaining a decoder identification (ID) value of a decoder; generating, using an encoder, a symbol having the encrypted version of the private data item and the decoder ID value; and generating a hardcopy document by recording the symbol on a physical medium, where the hardcopy document is transported to a subsystem having the decoder, and where the subsystem decrypts the encrypted version of the private data item after extracting the encrypted version of the private data item from the symbol.

    • A print job canceling method for a printer is described and is especially useful in a printer with relatively small buffer memory. When a print job is cancelled by the user using the printer's control panel, this method allows the printer controller to receive additional print jobs while the current job is being cancelled, without having to notify the host to stop sending the current print job. The printer controller reduces the memory allocated to the job being cancelled. The printer controller continues to accept data for the current job from the host, but does not print the received data. The data is subsequently flushed from the memory. The printer controller also assigns a lower priority to the print job being cancelled. Meanwhile, the remaining memory can be used to receive and print additional print jobs.
    • 描述了打印机的打印作业取消方法,并且在具有相对较小的缓冲存储器的打印机中特别有用。 当用户使用打印机的控制面板取消打印作业时,此方法允许打印机控制器在当前作业被取消时接收其他打印作业,而不必通知主机停止发送当前打印作业。 打印机控制器减少分配给正在取消的作业的内存。 打印机控制器继续接受来自主机的当前作业的数据,但不打印接收到的数据。 数据随后从存储器中刷新。 打印机控制器还为要取消的打印作业分配较低的优先级。 同时,剩余的存储器可用于接收和打印其他打印作业。
