How to distinguish the effectiveness of a tablet printer?

　　　　How to distinguish the effectiveness of a tablet printer? This is a problem that many users encounter when purchasing printers. Let's listen to the introduction of the printer manufacturer:　　Mastering the following five techniques can easily distinguish the quality of a tablet printer.　　1. A tablet printer first requires accurate printing. The corners, edges, and levels of the pattern must be printed accurately without any ghosting or dark marks.　　2. The tablet printer prints neatly and flawlessly. The screen and blank areas should be clean and tidy, without any scars or dirt. The printing on a tablet printer should be uniform and consistent. Both deep and light ink tones should be uniform, and the concentration should be consistent, without any unevenness or uneven handwriting.　　3. The tablet printer has clear graphics and text. The image is clear, the contour is realistic, the texture is strong, and there is no blurring or blurring. The writing style is clear and beautiful, with

Wireless communication for printers

　　　　telecommunications　　Infrared (IrDA), Bluetooth (BLUETOOTH), WIFI (802.11b/g), RF2.4G wireless, RF433MHz wireless　　Infrared technology was still used on many portable printers before 2007, but as laptops and mobile phones gradually phased out infrared technology, fewer and fewer printers used infrared technology　　The wireless data communication technology of Bluetooth based mainstream portable printers has the advantages of low power consumption and directionless, but the disadvantages are limited transmission distance and cumbersome setup and pairing in the early stage　　WIFI is a technology used by some portable ticket and label printers, which has the advantages of long transmission distance and no directionality. The disadvantage is that it has higher power consumption for printers that rely entirely on batteries to operate　　RF2.4G wireless belongs to the free frequency band for civilian use. With the maturity of technology and the decrease in cost, it has been widely used in th

What are the VID and PID of USB, and what are their functions?

VID: Vender ID supplier identification codePID: Product ID product identification codeEvery USB (Universal Serial BUS) has VID and PID. The VID and PID values are actually the unique identification ID of the USB device connected to the Windows system. When the device is connected to the computer via USB, its driver depends on it.The VID is applied by the supplier to the USB-IF (Implementers Forum). The VID of each supplier is unique, and the PID is determined by the supplier. The host uses VID and PID to identify different devices, and according to them (and the version number of the device), it can load or install the corresponding driver for the device. Both VID and PID are two bytes in length. Usually the VID and PID of the device are composed of a string of characters, such as: USB\VID_04A9&PID_1761, "_" indicates the specific VID and PID values.How to check the vid and pid of the usb device?View as follows:1. Insert the USB into the computer,2. Right-click [This PC], select [Ma

Analysis and solution of printer malfunction reasons

　　　　During use, the printing accuracy of the printer may gradually deteriorate due to the number of times and duration of use. However, if the printer is new and often experiences unclear printing lines, skewed text and graphics, blurry outer boundaries of text and graphics, and poor synchronization accuracy of ink output control, it indicates that there has been an internal malfunction in the printer! What specific faults are they and how should they be resolved?　　1、 Printer paper jam deformation　　This situation mostly occurs in humid weather, as the cardboard boxes are usually designed at the bottom of the body, which can easily cause paper deformation and lead to paper deviation on the paper path. The solution is to put a package of desiccant in the cardboard box. Of course, there is also a possibility that the aging or damage of internal components of the printer may affect the smoothness of the paper path. You can open the printer and carefully observe the position of the paper j

What materials do UV flatbed printers need to use coatings for processing

　　　　Although UV flatbed printers can print patterns on surfaces of hundreds or thousands of materials, differences in surface characteristics, UV ink adhesion, flexibility, and other properties can lead to peeling and detachment on some materials, which requires the use of UV coatings to solve this problem.　　1. UV flatbed printer silicone coating　　Suitable for silicone and rubber materials. The surface activity is poor and requires flame treatment, otherwise the adhesion is insufficient. Flame treatment depends on experience, and the surface should not be sprayed too thick, otherwise it is not easy to dry.　　2. Metal coating for UV flatbed printer　　Metal coating: suitable for materials such as aluminum, copper plate, tinplate, aluminum alloy, etc., available in transparent and white colors, and should be used on finished products. It cannot be used before stamping or injection molding, otherwise the effect will be greatly reduced.　　3. Leather coating for UV flatbed printers　　Suitable f
