How to test the stability of printer ink?

　　　　Ink is the most consumable material for printers, and without ink, it is impossible to print materials. The quality of ink determines the printing effect and also has an impact on the printer itself. The quality of ink is largely determined by its stability. If the stability is poor, the ink quality will inevitably be poor. So how to test the stability of printer ink?　　1. High temperature testing　　After placing the printer ink in a high-temperature environment (55 ℃ to 70 ℃) for one week, restore it to room temperature of 20-25 ℃ and let it stand for 24 hours. Conduct a continuous printing test on the machine for no less than one hour, and ensure that the ink does not line or change color during continuous printing.　　2. Low temperature testing　　After placing the ink of the tablet printer in a low-temperature environment (-37 ℃ to -46 ℃) for one week, restore it to room temperature of 20-25 ℃ and let it stand for 24 hours. Conduct a continuous printing test on the machine for at le

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

Wireless Thermal Label Printers

　　　　Wireless thermal label printers have revolutionized the way labels are printed, offering unparalleled convenience and flexibility in various industries. These printers utilize thermal printing technology, which involves heating a special thermal paper to create text, barcodes, and graphics. The wireless connectivity, typically via Wi - Fi or Bluetooth, enables seamless integration with different devices such as smartphones, tablets, and computers.　　One of the key advantages of wireless thermal label printers is their portability. They are compact and lightweight, making them easy to carry around in a warehouse, retail store, or even during field operations. For example, in a busy retail environment, sales staff can use a wireless thermal label printer connected to a tablet to quickly print price tags, product labels, or shipping labels. This eliminates the need for a wired connection, allowing for greater mobility and efficiency.　　The setup process of these printers is also extrem
