摘要： An incremental impact printer of the dot matrix type. Binary words representative of data to be printed along a line of print may be accepted from either the printer keyboard or the output of a computer or other source. The printer electronics provides for either a single character or a burst of characters to be substantially instantaneously printed upon receipt. The print head is always moved to the right of the last character printed to facilitate observation of that character. The next character is printed by first moving the print head to the left of the last character printed and then abruptly reversing the print head to print one or a burst of characters "on the fly". A novel registration system serves the dual function of accurately locating the proper position for a character to be printed and determining the direction of movement of the print head at any given instant. The printer has a capability of receiving characters at a rate of 75,000 characters per second and of printing at a rate of up to 120 characters per second. The device can also be utilized in the transmission mode with the transmission rate through communication of other links being a function of the operator's typing speed. The printer is further capable of simultaneously accepting data while performing a printing operation.

摘要翻译： 点阵式增量冲击打印机。 可以从打印机键盘或计算机或其他来源的输出接受代表沿打印行打印的数据的二进制字。 打印机电子装置提供单个字符或一串字符在接收时基本上被即时打印。 打印头总是移动到打印的最后一个字符的右侧，以方便观察该字符。 首先将打印头移动到打印的最后一个字符的左边打印下一个字符，然后突然反转打印头，以便在“即时”中打印一个或一串字符。 一种新颖的注册系统具有精确定位要打印的字符的正确位置并确定打印头在任何给定时刻的移动方向的双重功能。 打印机能够以每秒75,000个字符的速度接收字符，并以每秒最多120个字符的速率打印。 该设备也可以在传输模式下被利用，通过其他链路的通信是通过操作者的打字速度的函数的传输速率。 打印机还能够在执行打印操作的同时接收数据。
