As computer network technology will be widely used in prepress publishing systems, in order to improve work efficiency and save money, network printers will definitely be introduced. The goal of network printing is to solve important and long-term work efficiency problems, reduce office expenses and share resources reasonably. Therefore, network laser printing technology is not only a device technology problem, but also a network printing system technical problem. As the network continues to evolve and its capabilities continue to grow, there is a growing need for a powerful, reliable, and intelligent network printing solution. Therefore, in the era of the rapid development of the Internet and private networks in various industries, network printing is not a fashionable, but a dazzling new role.
Prepress publishing itself is a work centered on information transfer, and will increasingly turn to the network for information and network printing. A truly complete network printing solution should include three factors: one is a network printer with perfect network connection function; the other is the printer and network connection device, generally called network print server; the third is to manage network printing. software. When introducing the network printing technology, the prepress publishing system can reasonably configure the grade and quantity of the network printer according to the scale of the publication and the setting of the organization, and uniformly manage the use and maintenance of the printing equipment, and should be correctly installed in daily work. Use a network laser printer. In order to be able to adapt to the application of new technologies and the development of publications, the publishing industry should actively introduce network printing technology to meet the challenges of the upcoming information network.
First, the composition and characteristics of the network printing technology equipment
Network printing is the ability of a user to drive a printer in any location, using any web browser. The most significant advantage of network printers is their ease of management. If every computer comes with a printer, the management and maintenance of the printer will be complex and inefficient, even if several computers share a printer, the situation will not improve much. By hanging the printer on the Internet, each printer is distributed in various departments, and the administrator can monitor the working status of each printer through any computer, which greatly improves the printing speed and reduces the cost. Network printing eliminates the one-to-one traditional mode of configuring a printer in a computer in the past, and dedicates the printer as an online hardware resource to the office group for sharing, which can save limited funds and improve print quality, saving office space and facilitating. service. In addition, it also has many potential related benefits, you can freely travel in the unlimited space of the network, and printing is on your side, as long as you can see it, you can feel it, undoubtedly broaden the office space and time, improve office efficiency.
1. Network printing system
Network printing systems include: network printers, network print servers, and software for managing network printing.
The network printer directly connects to the network adapter card through the EIO slot, enabling high-speed printouts at the speed of the network. The modern meaning of "network printing", it is a high-end network printing. Network printing has emerged as a stand-alone print server as a separate requirement and function. From then on, the printer is no longer a peripheral to the PC, but becomes a separate network connection.
Network laser printer is a standard information output device after computer network technology and web application are closely combined. It not only meets the needs of high-speed network development, but also meets the needs of centralized office management, and can greatly improve printing speed and printing in network environment. Quality and system print management efficiency. Network laser printers mainly involve two parts: network technology and printing technology. The quality of the printing function is the same as that of ordinary laser printers (dpi), resolution increasing technology (RET), halftone processing (including dot size). In addition to the five basic technologies of the print engine's electronic photo processing, page description language, printing speed, monthly print output, printing paper processing capacity and printer management capabilities, and even some user-friendly Software technology for network work. From the perspective of printer application technology, the biggest difference between the popular network laser printer and the general laser printer is that it can directly connect to the network through the print server carried by the printer, and can realize the transmission of print data at the network transmission speed. Therefore, the network laser printer not only has excellent output performance in terms of printing accuracy and print quality, but also has a printing speed that is much higher than that of a personal laser printer. Especially in the aspects of printer equipment management, user file management, etc., with the network printing management software, users can monitor the situation of multiple network laser printers at any time, even if they are out, they can remotely control through the Internet to solve any problems that occur.
The network print management software is a software specially used for managing network printers. The software is managed by running the software, and the interface is excellent and the operation is convenient.
The print server represents the modern meaning of "network printing", which is a high-end network printing. The printer is no longer a peripheral of the PC, but becomes a separate network connection. The network printer directly connects to the network through the EIO slot. Cards enable high-speed printouts at the speed of the network. The widely used PC server represents traditional shared printing. It is a low-end network printing. The printer is in the position of a PC peripheral. It mainly uses a PC server or a sharer to implement a simple network connection, but the data transmission is still It must be done through the parallel port of the printer, so the speed is very low.
The print server is the most important component in determining the difference between network printing and traditional shared printing. It not only connects any printer to any part of the network, but also enables network transmission between the network printer and each computer terminal. Speed, and remote management of network print jobs through management software. And if the print server is only a connector between the network and the printer, then it not only has no users, but also affects the promotion of network printers. At present, HP's "four-in-one" network printing solution can be simply expressed as "network printer + network print server + print management software + professional services", of which "network printer" has multiple operating system multi-protocol adaptability, " The Network Print Server is designed for professional processing and easy operation. The Print Management Software enables comprehensive management and fast printing, while its "Network Printing Professional Service" can meet the different needs of different industries. Such standards and solutions maximize the user's need for efficiency, cost, manageability, and ease of operation.
2. Features of network printing
The use of network printing technology has the following salient features:
2.1 There is a clear difference between using a print server and using a traditional PC server for network printing. 2.2 The biggest difference between a network printer and a general printer is that it has three characteristics: manageability, ease of use, and high reliability. The core of these is manageability. 2.3 network laser printer server has excellent performance, ensuring high quality network printing.
In the prepress publishing system, the role of printing is becoming more and more important. The network laser printer server is one of the core components of network printing and one of the most important symbols of network printing. It should have the following outstanding performance: high speed, high resolution, high quality; flexible and fast network function; lower The cost of printing.
Second, the basic installation steps of the network laser printer
1.IP address setting
After completing the hardware connection between the printer and the network, first assign an IP address to the printer. The IP address of the network laser printer can be obtained through the following three methods: one is that the print server supporting DHCP can be automatically allocated by the server in the network supporting DHCP; the second is that the network management software is provided by the manufacturer, and the settings are allocated through the server or the terminal; The third is manually configured on the printer control panel. In the latter two modes, you need to apply to the network administrator for the IP address of the printer, and get the corresponding subnet mask, and then write the IP address and subnet mask to the print server in the printer panel or setup software.
2. Create a network port
After the printer's IP address is set, create a network port on the server or terminal computer where the printer is to be installed. Most vendors provide Win9x and Windows.
Network port installation and creation procedures under NT, you can follow the prompts to create the corresponding network port. There are also some standard network print ports under Windows NT, the most common of which are LPR mode ports, but to use this method, be sure to use Windows.
Add TCP/IP Printing service to NT.
3. Install the driver
After the port is created, you can install the printer driver just like a normal printer. Be careful not to forget to select the created network port as the port to connect to the printer during the installation process. For Windows The printer installed under NT has a terminal shared by Win9x, and you must also install the driver under Win9x as prompted.
4. Sharing settings
When installing a printer under Windows NT, it will automatically prompt whether to provide printer sharing to other computers on the network, and Windows.
NT shared printers, other terminal computers only need to find the corresponding printer, and will automatically prompt the installation process after clicking. For printers installed on Win9x computers, you need to set them to share in the printer properties options after the printer is installed. Also, allow printer sharing in the network properties of the computer.
5. Choose the right network installation method
During the network installation process of the printer, different installation methods should be selected according to actual needs. If there are more terminal computers in the network, the configuration of the machine is more complicated, and the number of network printers is relatively small. You can choose the print queue installation mode to facilitate centralized management of the printer. The disadvantage of this installation method is that the printing process takes up server resources. And have a certain dependence on the performance of the server. If a terminal wants to cancel the print job, it can only be implemented by the network administrator. If there are no special personnel to manage the network and printers, the number of network printers is relatively large. You can consider the point-to-point installation method. Not only does it have the disadvantage of lack of resources, but also the installation method is flexible, but because there are no problems of permissions and priorities, Not conducive to the management of the printer. In actual use, it is also possible to use two methods of coexistence.
Third, the network laser printer sharing setting method
1. Set up network laser printer sharing
After installing the print driver, open the “Start Menu” → “Settings” → “Printer” under the WIN98 operating system. The correctly installed printer icon will appear in the folder. Right click on this icon and select “Share”. In the "Sharing" tab, click "Share as", fill in the name of the share in the "Share Name" to complete the sharing settings of the network laser printer.
2. Configure the network sharing protocol
In order to be able to perform shared printing, the microcomputer in the LAN must have the "Sharing Protocol for File and Printer" installed. Click "Network Neighborhood" on the WIN98 desktop, then click the right mouse button to open the "Network" dialog window, and then click "File and Printer Sharing"; in the "File and Print Sharing" dialog box that pops up, select "Allow The "Other users access my files" and "Allow other computers to use my printer" checkbox, and then click the "OK" button; the system will prompt to insert the Windows98 system installation disk, specify the installation directory, then The sharing protocol for the file and printer will be automatically installed; after the installation is complete, the system automatically asks to restart the computer, and the new sharing settings take effect after the restart.
3. Client installation and configuration in the network
The above two steps only complete the network setting of the microcomputer connected to the network laser printer, and must also set up other microcomputers in the network that need to share the network laser printer. In the network, each computer that wants to use the shared network laser printer must be installed. Print the driver, and then do the following steps: Click "Start" → "Settings" → "Printers", then double-click "Add Printer", start the "Add Printer Wizard", click "Next"; when the wizard asks When the computer is connected to the printer, select the "Network Printer" option, click "Next"; enter the network path of the printer, that is, you need to specify the name of the network laser printer, you can click the "Browse" button in the workgroup In the network laser printer, select the network laser printer, click the "OK" button, select the network path of the printer, click "Next"; the system will prompt to enter the printer name again, after input, click "下下One step button, then press the "finish" button, such as Network laser printer set a password, it asks for a password; and finally add a network laser printer icon in the Printers window. By setting up such a network for all the microcomputers in the network, the sharing of the network laser printer can be realized in the local area network.
Fourth, how to improve the working efficiency of network laser printers
The use of network laser printers can improve the efficiency of the system and save resources. In daily use, the network laser printer can be operated efficiently by the following methods.
1. Use a computer with a higher configuration
If the network laser printer is installed on a computer connected to the network for shared printing, the computer connected to the printer should use a high configuration, so that the operating efficiency of the network laser printer can be guaranteed, the computer's CPU, memory, hard disk, network card Equipment is a factor to consider.
2. Use high performance network laser printer
Since the workload of the network laser printer is different from that of the ordinary printer, in order to meet the batching and rapid printing requirements of the newspaper news editing system, it is required to have high performance when selecting a network laser printer. The higher performance is first manifested in the network laser printer must have strong paper processing capabilities, should try to use a network laser printer with a large number of different paper storage, paper storage capacity, which can not only improve the network printing capabilities, It can further improve the automation of network printing; the higher performance is also reflected in whether the printing speed of the network laser printer itself is fast enough, if the printing speed of the network laser printer itself is very slow, then no matter how to improve the performance of the computer or Network optimization can not effectively improve the efficiency of network printing. In addition, high-performance network laser printers should be able to handle different types of print objects, especially to ensure the printout of image files in newspaper news editing systems.
3. Use a network laser printer with a built-in network card
When using network printing, choose a network laser printer with a built-in network card or a built-in network card, you can directly connect to the network to achieve shared printing; in addition, only by selecting such a network laser printer, the system can withstand high load operation and ensure The printing speed of the network.
4. Must use a large network laser printer
When performing network printing, sometimes it is necessary to send many print jobs to the printer at the same time. In order to make these print jobs can be processed quickly and accurately, the printing does not occupy too much network resources, and the stable operation of the entire local area network should be selected. A large network laser printer, such a network laser printer can process files quickly, so that many print jobs do not block the network or be lost. In addition, in order to meet the increasing demand for information processing resources, the network printer's memory should also be scalable, this upgrade not only includes its memory capacity can be upgraded, and even its core control software should be upgradeable.
5. Must use a network laser printer that supports multiple network protocols
The most basic requirement for using a network laser printer is to be able to handle various types of print tasks quickly and easily. If a LAN uses a networking method using a variety of different protocols, the network laser printer cannot meet each of the LANs at the same time. A network laser printer cannot operate normally under the printing requirements of a network environment. With the widespread use of the Internet today, it is particularly important to use a network laser printer that supports multiple network protocols.
6. Must choose a network laser printer with network management function
Select a network laser printer with network management function. When the printer fails to print, it will diagnose the cause of the fault accurately and timely, and send the diagnosis result feedback to the operator so that the operator can handle the fault in time. The network laser printer with network management function also has a reverse monitoring function. With this function, the network printer can automatically stop the printing task with a large amount of work, so as to prevent the printing job from being lost or the network from being blocked due to the increase of the workload. In addition, the network laser printer with network management function can also queue the jobs received later when processing the previous print job, thereby preventing the loss of the print job.
7. Must ensure the smooth running of the network
Since the network laser printer realizes shared printing through the network, the running speed of the network laser printer is closely related to the smoothness of the network line. The smooth flow of the network is mainly related to the exchange or transmission speed of switches, hubs, network cables and network cards in the local area network. It is better for the newspaper's news editing system to use 100M bandwidth network switching equipment to set up the local area network to ensure that the LAN line transmits large-capacity information. Information jams do not occur frequently. In addition, the smooth network of the LAN is also related to whether the LAN is busy or not. When using a network laser printer for high-volume printing, it is best to avoid the peak period of network usage.
8. Must optimize the computer operating system
Optimizing the computer operating system can improve the operating efficiency of the microcomputer system and save a lot of system resources. The use of computers in the network will occupy a large amount of system resources. Therefore, rational allocation of system resources is a problem that the network system must consider, using a network laser printer. More so. You can optimize the use of the computer by installing and running some insignificant applications as little as possible in the microcomputer, regularly arranging the hard disk, and saving the computer memory.
9. The print port must be set correctly
If the print port is set incorrectly, the network laser printer will not operate normally. The current network laser printer is usually connected to the computer through the serial port. Most newspaper news editing systems use professional prepress processing systems. The network laser printers configured in these professional prepress systems use a special interface card to connect with the computer. Make sure that the installation is correct.
10. Print parameters must be set properly
Whether the print parameters are set correctly or not will also have an impact on the efficiency and quality of network printing. For example, if you need to print a fine printed image, you can set the resolution of the printer to a higher level, the accuracy of the printed image will be higher, and the quality of the printed will be better.
