摘要：
A peripheral such as a printer is controlled to receive data from different data ports. A first port receives data formatted according to a first protocol. A second port receives data formatted according to a second protocol. A first processor is associated with the peripheral. A second processor is associated with the second port. A switch is adapted to receive (i) first data from the first port and (ii) second data from the second port after processing by the second processor. The switch is controlled in response to a command received via the second port to couple either the first data or second data to the first processor for use in controlling the peripheral. New firmware can be downloaded to the peripheral via the second port in response to the command. The command can be communicated to the first processor via a separate port at the first processor and a memory shared with the second processor.
摘要（中）：
控制诸如打印机的外围设备从不同的数据端口接收数据。 第一端口接收根据第一协议格式化的数据。 第二端口接收根据第二协议格式化的数据。 第一处理器与外围设备相关联。 第二处理器与第二端口相关联。 开关适于在第二处理器处理之后接收（i）来自第一端口的第一数据和（ii）来自第二端口的第二数据。 响应于经由第二端口接收到的命令来控制开关，以将第一数据或第二数据耦合到第一处理器以用于控制外围设备。 响应命令，可以通过第二个端口将新的固件下载到外设。 该命令可以经由第一处理器处的独立端口和与第二处理器共享的存储器传送到第一处理器。
