摘要： An output device is enabled to obtain character descriptions for use in raster scanning characters which belong to a common character font. Character descriptions are stored in an external device which is linked to the output device by a communication channel. Character codes are received at the output device which identify characters to be outputted. A raster image of the characters to be outputted is set up. In the course of setting up the raster image, information corresponding to the character codes is sent from the output device to the external device via the communication channel. In response to the character codes sent from the printer to the external device, corresponding character descriptions are sent from the external device to the output device via the communication channel.

摘要翻译： 输出设备能够获得用于在普通字符字体中使用的光栅扫描字符中的字符描述。 字符描述存储在通过通信信道链接到输出设备的外部设备中。 在输出设备处接收字符代码，其识别要输出的字符。 要输出的字符的光栅图像被设置。 在设置光栅图像的过程中，通过通信信道将与字符代码相对应的信息从输出设备发送到外部设备。 响应于从打印机发送到外部设备的字符代码，相应的字符描述通过通信信道从外部设备发送到输出设备。
