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
2024-06-21Check the status of printer accessories If there is an issue with the offset of the printing paper, it may be caused by an issue with the status of the printer accessories. You can check the printer accessories, such as ink cartridges, ribbons, paper stacks, etc., to ensure they are in normal condition. If any accessories are damaged or need to be replaced, it is recommended to replace them in a timely manner. 2. Reinstall the driver program If the printer driver installation fails or is damaged, it may cause issues with abnormal paper positioning. You can try reinstalling the driver or upgrading to the latest version of the driver. When installing drivers, it is important to choose the correct driver based on the printer model. 3.

2024-06-21Firstly, ensure that the printer is properly connected to the computer and the power is turned on. Check the printer settings to ensure that it is set as the default printer and that the paper size and type are set correctly. If the printer is connected via Bluetooth, ensure that the Bluetooth pairing between the phone and the printer is successful and within the range of use. For paper positioning issues, you can try paper calibration. For example, for certain models of printers, manual paper calibration can be performed by long pressing the printer button, waiting for the blue light to flash twice, and then releasing it. In addition, if the display shows abnormal label positioning, you can try to feed the paper again and confirm if the paper type is supported, or select center detection in the printer settings to feed the paper again. If the inaccurate printing position is caused by a paper measurement issue with the barcode label printer, it can be resolved by performing a pa

2024-06-20Bluetooth printers are a very practical printing tool that can bring a lot of convenience to people's daily life, work, and more. However, sometimes when using Bluetooth printers, we may encounter issues with abnormal positioning, which is very distressing. So, how can we solve the problem of abnormal positioning of Bluetooth printers? Below we will introduce some common solutions. Method 1: Re pair If the positioning of the Bluetooth printer is abnormal, you can try pairing again. Some Bluetooth printers may experience pairing abnormalities during use. At this point, we can delete the pairing information between the Bluetooth printer and the computer or phone, and then pair them again. Method 2: Check the Bluetooth connection status If the positioning of the Bluetooth printer is abnormal, it is also possible that there is a problem with the Bluetooth connection status. At this point, we can first check the Bluetooth connection status to see if it is already connected or if it
2022-11-26Thermal paper is a special coated processed paper whose appearance is similar to ordinary white paper. The surface layer of thermal paper is smooth. It is made of ordinary paper as the paper base, and a layer of heat-sensitive color-developing layer is coated on the surface of the ordinary paper. The color-developing layer is made of adhesive, color developer, colorless dye (or It is called leuco dye) and is not separated by microcapsules, and the chemical reaction is in a "latent" state. When the thermal paper encounters the heat-generating print head, the color developer and the leuco dye in the place where the print head prints will undergo a chemical reaction to change color and form a graphic.When the thermal paper is placed in an environment above 70°C, the thermal coating begins to change color. The reason for its discoloration also starts from its composition. There are two main heat-sensitive components in the thermal paper coating: one is a leuco dye or leuco dye; the other
