打印机、个人计算机和打印系统
摘要：
当接通电源时，打印机(10)选择并读取大容量存储器类别驱动器(59)并由经由USB电缆(11)连接到打印机(10)的个人计算机(20)将其识别为存储设备。在PnP通信(S10、S37)之后，个人计算机(20)从打印机(10)接收用于切换程序的可执行文件(S15)并启动切换程序。在使用安装在个人计算机(20)中的编辑器的情形下，打印机(10)需要操作为打印设备(S19处为是)。个人计算机(20)因此使用切换程序向打印机(10)传送用于切换打印机(10)的工作状态的信息。打印机(10)选择和读取打印机类别驱动器(58)以将工作状态设定为打印设备状态(步骤S43处为是，步骤S45处为否)。
摘要（英）：

When a power is turned on, a printer (10) selects and reads a mass storage class driver (59) and is recognized as a storage device by a personal computer (20) connected to the printer (10) via a USB cable. After PnP communication, the personal computer (20) receives an executable file for a switching program from the printer (10) and starts up the switching program. In a case where an editor installed in the personal computer (20) is used, the printer (10) needs to be operating as a printing device. The personal computer (20) therefore uses the switching program to transmit to the printer (10)information for switching an operating state of the printer (10). The printer (10) selects and reads a printer class driver (58) to set the operating state to a printing device state.
