I. Basic introduction The Internet is a trustworthy media. It allows information to be quickly transferred, exchanged, and popularized at a low cost. It allows us to access almost any topic of any information, which greatly increases the amount of information for printing. Because we can not only print specially generated information on the Internet, we can also print web pages to achieve remote printing of information. With the popularization and standardization of the Internet, the Internet will be as ubiquitous as the telephone system. By then, more information will be available through the Internet.
Some people may say that the information transmitted by the Internet can be seen on the display screen and it is not necessary to print it at all. However, paper media media have the advantage of being portable, and most people are already accustomed to reading printed matter. This is how Internet printing can be developed. An important reason.
The traditional way is to print the required documents locally and mail them to the destination. If you want to achieve immediate delivery, you must send a fax. Not only does it have to pay high phone charges, but the copy quality is also not good. In addition, E-mails can also be sent directly, but most smart ISPs limit the data length of E-mail files, so high-quality files cannot be delivered via E-mail.
A good way to solve the above problems is to implement Internet printing. The documents that need to be printed are directly transmitted to printers all over the world through the Internet. Such printing methods have high quality, low consumption, and low cost.
One of the keys to the current realization of Internet printing is to achieve the unification of regional agreements. Because there are a lot of different protocols for local printing. The basic motivation behind the establishment of an Internet printing protocol is to allow different companies to have a unified standard that they can all follow, that is, to allow printers in different regions to follow this standard, so as to use the advantages of the Internet to achieve information transfer and printing between different locations. In Other words, when different companies in different regions use the same standard, they can transfer and print document materials through the Internet.
Figure 1 below shows a basic schematic diagram of Internet printing. It can be seen that Internet printing is essentially an extension of local printing, and this extension is achieved through the Internet.

Second, the printing structure of the Internet printing company In the Internet printing, the printing process of enterprises contains a large number of technical factors, including LAN, the World Wide Web related technologies, involving the basic mode of printing press access LAN, printing, follow Agreements, operating systems used, etc.
The current Internet printing is more and more complicated, there are roughly two reasons. On the one hand, due to the special requirements brought about by the use of different network operating systems, both Novell and Microsoft have their own operating systems and require corresponding settings. On the other hand, due to the limitations of proprietary technologies provided by various printer vendors for management and configuration, such as a large number of management protocols and different internal and external network ports, the current network management protocol is typically a network printing alliance protocol ( NPAP), Data Connection Control Protocol (DLC), Novell Service Access Protocol (NSAP). In addition, each vendor must bundle its own proprietary software to control and manage its own presses. In this way, one of the daunting tasks of implementing Internet printing is how to implement the management of different network printers.
It can be seen that in the field of Internet printing, the printing structure of enterprises has undergone great changes, and new requirements have been raised in terms of management, directory services, printing protocols, and security. This also prompted people to develop a unified standard for various network printer management software and protocols. Currently, the printing industry has established the SNMP (Simple Network Management Protocol) protocol for printer management, but printer vendors still bundle their proprietary software. Of course, with the popularity of the Internet, vendors have recently begun offering web browsing management functions that will support the SNMP protocol, which will allow the press to automatically support most operating systems. In addition, because SNMP itself is a basic network standard, it has become a mandatory protocol that network printers must follow. Web browsing management and the SNMP protocol together are enabling the management of all corporate presses to be managed in the same way. In fact, the Internet must also guide the future direction of printing companies.
Third, the special requirements for Internet printing The ideal Internet printing protocol should make full use of existing Internet protocols and standards. This not only can shorten the process of installing the agreement, but also can make the content of the agreement more focused on the printing environment, rather than being low. Horizontal transmission protocol. The most widely used Internet protocols are TCP/IP (Transmission Control Protocol/Internet Protocol) and HTTP. Strictly speaking, TCP is a transport-level protocol, and HTTP is an application-level protocol.
From the expectations of the terminal printers, their requirements for the printing of the Internet are basically the same as the requirements for traditional printing, including the progress of seeing the work at any time, understanding the specific requirements of the user, obtaining a list of unfinished work, and so on.
System administrators must be able to track and control printers at remote sites, and end-users should be as convenient as using local printers when using off-site printers.
In Internet printing on the LAN, security is not a problem because printers are relatively inaccessible to other companies, so files do not need to be encrypted before they are sent to the printer. But it's different on the Internet. Usually any information coming into the printer (or the printer's server) needs to be verified and encrypted. At present, almost every company that links to the Internet uses a firewall. It only supports certain protocols. These protocols are usually based on TCP or UDP (User Datagram Protocol) port number. A brand-new protocol will have a new port number. The firewall will only support this after confirming this port. New agreement.
Another special requirement of Internet printing cannot be found in a typical network environment. It is to provide a directory of local printers to indicate their respective printing capabilities and asset status. This directory service is similar to the yellow pages for telephone numbers. It can Help users choose the network printer that best suits them.
Cooperating with foreign printers may also require certain word processing and conversion. For example, the information provided by a foreign printer may be described in the local language. The operating system of the user or customer must be able to support this language. Otherwise, the operating system will stop running these strings. Therefore, it is necessary for the Internet protocol to pass a text string or The name communicates with users to solve some problems brought about by internationalization.
A typical printing method in the MS-Windows environment requires a local printer driver to be installed on the user's computer, and the PDL (Page Description Language) data stream generated by the driver can be read by the printer. One of the most common forms of PCL (Print Control Language), but also Postscript or other language forms.
In the case of remote printing on the Internet, it is also necessary to install a driver capable of generating a PDL, regardless of whether the driver is installed on the user host or at the site where the printer is located. There are also situations where there is no need to install a local printer driver. For example, when IPP (Internet Printing Protocol) is installed on the server, it is possible to embed the drive on the server. The user file will be in the form of a Windows enhanced metafile (large file). Transmission, so there is no need to install a local print driver.
