Scanners, printers, speakers, mice, and keyboards are computer peripherals, or computer peripherals. Peripheral devices can be broadly divided into three categories: 1 Human-computer interaction devices, such as printers, monitors, plotters, and language synthesizers.
2 Storage devices for computer information, such as disks, optical discs, tapes. 3 .Machine communication equipment, such as two computers can use ** line communication between them, they can be done through a modem.
Peripherals can be simply understood as input devices and output devices. For example, the monitor is only an output device used to display computer information, and the mouse and keyboard are input devices used to input information, which are all peripherals. A general term for input and output devices and external memory in a computer system.
It plays a role in the transmission, transfer and storage of data and information. It is an important part of a computer system.
Scanner. Mice, keyboards belong to input devices. Printers and speakers belong to output devices.

The printer is scannable. Usually the printer has a scanning function, that is, it can scan the physical object into a digital ** stored on the computer. The output speed and output quality of the printer have always been very valued by enterprise users.
The high-speed output speed can greatly improve office efficiency, imagine if the output speed is not high, then a lot of time and energy will be spent waiting for printing and copying when working.
The role of the printerIn addition to the speed and quality of the output, the function of the printer can be said to be very important. The copy and scanning functions are arguably the most common ones we use in our work, and it should be noted here that printing equipment can be broadly divided into two categories. One of them is an ordinary printer, which only has the function of printing, and the other is an all-in-one machine.
The printer's control panel was too complex to operate, especially for new employees who were using the printer for the first time. Even for the old employees who are proficient in controlling the equipment, the complex operation process greatly reduces the office efficiency of the employees, so the difficulty of the printer control panel directly determines the work efficiency of enterprise office users.

How to use the scanning function of a large printer:
1. Click the start menu in the lower left corner of the computer, and then click Devices and Printers. Double-click to open my default and ready printer, click Scan Document or ** on the right, put ** or file into the copier, click Start Scan and you're good to go.
2. After the scan is completed, a dialog box will pop up, asking you to enter a file name, just enter one, the import is successful, and the file storage directory will be automatically opened.
The printer scanning function means that the text on the paper and ** are directly converted into electronic versions and stored on the computer.
Printer Features:
The printer has the functions of Yuchai printout, input, communication and so on. As long as the ** cable and computer are connected, and then the power is turned on, it can be operated. Some multifunction printers allow printing, faxing, scanning, and copying operations to be carried out at the same time, and you can also set up functions such as fax, continuous copying, multi-function answering, and sending email.

The printer's scanning function means that paper documents can be uploaded to the computer in PDF or jpg format.
Scanning is to directly convert the text and ** on the paper into an electronic version and save it to the computer.
The first step of the copy and fax function is to scan the original, the second step of copying is to print out the document scanned in the inner sock source, and the second step of fax is to send the scanned document.
The photocopier with scanning function can scan the document to the computer and store it as an electronic document, jpg, pdf or tiff format, or it can be stored as a text file through some software.
The standard for measuring the quality of a printer:
A printer is one of the output devices of a computer that is used to print the results of computer processing on a related medium. There are three indicators to measure the quality of a printer: print resolution, print speed, and noise.
There are many types of printers, according to whether the printing element hits the paper, it is divided into impact printers and non-impact printers. <>

Printers are generally equipped with a scanning function that converts paper documents into electronic documents. Here are the general steps to scan a file:
1.Open the printer's scan cover, place the paper document to be scanned on the scan glass, and cover the glass.
2.Open the scanning software on the computer, you can find the corresponding software program on the printer disc or install the relevant scanning driver for the printer model on the computer. If the printer and computer are connected via a wireless network, you can use the network scanning function to scan directly.
3.On the main interface of the scanning software, set the scanning parameters, such as scanning resolution, scanning mode, output format, etc., and determine the target path of the scan.
4.Click the scan button and the printer will start scanning the paper document and transfer the scan results to your computer.
5.After the scan is complete, you can view the scan results in the target path, and perform operations such as scrolling, saving, printing, or sharing.
It should be noted that the operation mechanism of the scanning function may be different for different printer types and software versions, please refer to the instructions of the printer and scanning software for specific operations. At the same time, the scanning effect is related to the setting of the scanning parameters and the quality of the paper original, if the scanning effect is high, it is recommended to adjust the relevant parameters to achieve the best effect.

Scanners are multi-** devices. The scanner is an input device of the computer, and its function is to scan the appearance of written materials or physical objects such as **, **, film and manuscript materials into the computer, and form a file for preservation. In fact, scanners have become the third most important computer input device after keyboard and mouse.
The printer belongs to the output device in the multi-** device, and the output device refers to the device used to output the results of computer processing. The most commonly used output devices are monitors, printers, plotters, etc. The printer can print text and image information.
With the development of printing technology, printers used as multi-equipment mainly refer to laser printers and inkjet printers.

The main component of a dot matrix printer is the print head, and the 9-needle, 16-needle, and 24-needle printers usually refer to the number of print needles on the print head. According to the firing method, the print head can be divided into solenoid type, pat type, energy storage type, sound factor type and piezoelectric type. Here we take the printhead of the 24-pin printer LQ-1600K and AIZ3240 as an example to illustrate its working principle. >>>More
Let me tell you about it! This problem is generally the most common and is caused by a conflict with the printer driver, you can turn off the printer and the computer first! After 1 minute or so, start it, and try to print it, I think it's okay to get this kind of problem, if it doesn't work! >>>More
