What Are Laser Scanners
How Should the Connections Be?
These scanners, also found in industrial barcode printer systems, send a very thin laser beam onto the barcodes. The effect of the beams is actually an optical illusion, based on scanning a single laser beam across a line approximately 30 times per second. In this way, the speed and density of the scanning cause the laser point to be perceived as a line. Laser scanners generally have two major advantages: the first is that laser scanners have greater reading depths compared to CCDs. The second is their high speed and reading accuracy. The easiest way to connect a barcode scanner to a PC is usually through keyboard emulation methods. The keyboard emulation interface can be inside the scanner or provided by a small device connected to the PC's keyboard socket. Another connection method is RS 232 format connection. In these applications, which are also found in industrial barcode printer systems, transmissions are provided in accordance with electrical signal levels.
What Are Barcode Printer Spare Parts and Consumables?
External accessories and consumables in industrial barcode printer systems generally include: external dispenser interface, external keyboard, label rewinder/collector, wireless connection interface, print head cleaning kit, serial connection cable, parallel connection cable, USB connection cable, and batteries. Additionally, there is a charger, automatic label feeders, label stacking unit, extra memory card, and label design software.
