When you touch a barcode scanner, Windows Barcode Scanner you often encounter many difficult technical terms such as optical resolution (optical resolution), maximum resolution (maximum resolution), color resolution (color depth), scan mode, interface Way (connection interface) and so on. Then we will now introduce the basic knowledge of these bar code scanning guns, so that we can better understand the bar code scanning gun, we can buy bar code scanning gun can also be used as a reference. In fact, Windows Barcode Scanner, bar code scanning guns and bar code readers are one thing, just used to call different. Barcode Scanner Type:
Handheld barcode scanner. Handheld bar code scanner is introduced in 1987, the formation of technology products, shape similar to the supermarket cashier used in the hands of the same bar code scanner. The vast majority of the bar code scanner using CIS technology, optical resolution of 200dpi, Windows Barcode Scanner black and white, grayscale, color variety, which color type is generally 18-bit color. There are individual high-end products using CCD as a photosensitive device, can achieve true color, scanning effect is better.
Small drum bar code scanner. This is the intermediate product of hand-held bar code scanners and platform barcode scanners (which have been new in the past few years because it is built-in power supply and small size is called notebook bar code scanners). The vast majority of this product uses CIS technology, optics Resolution of 300dpi, there are two kinds of color and grayscale, color models are generally 24-bit color. There are also a small number of small drum bar code scanner using CCD technology, scanning effect is better than CIS technology products, but because of structural constraints, the volume is generally greater than CIS technology products. The small drum design is to fix the lens of the bar code scanner, and move the object to be scanned through the lens to scan, operation as the printer, the object must be scanned through the machine and then sent out, so the object can not be scanned Too thick. The biggest advantage of this bar code scanner is that the volume is small, but due to the use of a variety of limitations, such as scanning only thin paper, the scope can not exceed the size of the bar code scanner.
Platform barcode scanner. Also known as flat bar code scanner, desktop bar code scanner, currently in the market most of the bar code scanners are flat bar code scanner, is now the mainstream. This type of bar code scanner optical resolution between 300dpi-8000dpi, color bits from 24 to 48, Windows Barcode Scanner scanning format is generally A4 or A3. The advantage of flat is that, like the use of copiers, as long as the bar code scanner cover open, whether books, newspapers, magazines, photo negatives can be put up to scan, very convenient, and scan the effect is all common types of bar code scanning The best of the device.
There are other large format scanning large format bar code scanner, pen bar code scanner, negative bar code scanner (note not flat bar code scanner plus sweep, the effect is much better, Windows Barcode Scanner the price of course expensive), physical bar code scanning (Not a flat barcode scanner with physical scanning capability, a bit similar to a digital camera), and a lot of drum bar code scanners, which are mainly used in the field of printing and printing.
