Basic concepts of TCP/IP printing

In Windows NT, printing via TCP/IP is accomplished using the LPR (Line Printer

Request) protocol. Because LPR was developed for UNIX systems, comparing

Windows NT and UNIX implementations may be helpful.

The LPR protocol is a host-to-host protocol, rather than a host-to-printer protocol. When printing via LPR, the computer sending the print job assumes that it is sending the job to another computer, or print server, which sends the job to the printer. In UNIX terminology, the print server is called a remote host. The print server can have several printers connected to it. The way to differentiate between different printers when spooling to the print server is to print to a specific remote queue.

The following table summarizes these concepts of TCP/IP printing and the terminology used in UNIX and Windows NT environments.

Your Tektronix printer emulates a print server. Tektronix printers are accessed by giving an NT host a remote host name that will point to the printer. This is true only if the print job is spooled directly to the printer via its internal network interface, and not through an external third-party print server. If the print job is spooled through an external third-party print server, the remote host name is the TCP/IP address of the print server and the remote queue name is the name of the queue for that print server.

840, 780, 360 specifications

Xerox has long been a pioneer in the field of printing and copying technology, and its 360, 780, and 840 models exemplify the groundbreaking advancements made by the company in the late 20th century. These machines are significant not just for their capabilities but also for how they transformed workplaces into efficient hubs for document management.

The Xerox 360, introduced in the 1970s, was notable for its innovative use of electrostatic transfer technology. This method allowed for the rapid and high-quality reproduction of documents, setting a new standard for both speed and clarity. With a printing speed of up to 120 copies per minute, the 360 was designed for high-volume environments, making it ideal for businesses that required efficient document distribution. Its ability to handle different media types, including transparencies, further expanded its utility.

Moving on to the Xerox 780, released shortly after the 360, this model built upon its predecessor's success by introducing additional features that catered to the evolving needs of users. One of the key advancements in the 780 was its ability to incorporate advanced finishing options, such as stapling and hole-punching, directly from the machine. This integration streamlined document production processes, reducing the need for manual tasks and enhancing workflow efficiency. The Xerox 780’s intelligent control panel also provided users with easy navigation and troubleshooting, minimizing downtime.

The Xerox 840 took another leap forward, focusing on integrating digital technology into the printing process. Introduced in the early 1980s, this model featured enhanced digital image processing capabilities, resulting in superior image quality and consistency. The 840 also supported duplex printing, allowing for automatic double-sided copies, which not only saved paper but also demonstrated a commitment to sustainability practices as environmental concerns began to rise. The combination of these features made the 840 particularly well-suited for corporate environments where document quality and efficiency were paramount.

Overall, the Xerox 360, 780, and 840 series were landmark achievements in photocopying technology. Their advanced features, such as high-speed output, diverse media handling, and enhanced finishing options, established Xerox as a leader in the industry. These machines not only improved productivity but also set a precedent for future innovations, influencing the trajectory of printing technology for years to come. As businesses continue to evolve, the foundational technologies pioneered by these models remain integral to modern document management solutions.
