Laser scanning is the controlled deflection of laser beams, visible or invisible. [1] Scanned laser beams are used in some 3-D printers, in rapid prototyping, in machines for material processing, in laser engraving machines, in ophthalmological laser systems for the treatment of presbyopia, in confocal microscopy, in laser printers, in laser shows, in Laser TV, and in barcode scanners.
Hewlett-Packard (HP) developed the first ScanJet in the mid-1980s at their printer division in Boise, Idaho. [4] [5] The ScanJet was released in March 1987, [6] as a compliment to their LaserJet series, which was the first commercially successful line of laser printers ever released, [7] introduced in 1984 and also developed at Boise.

The bed of the scanner is typically made of glass, and care needs to be taken that the glass not be scratched or cracked when placing or removing items on the bed. Since the items to be ...
Many MFP types, regardless of the category they fall into, also come in a "printer only" variety, which is the same model without the scanner unit included. This can even occur with devices where the scanner unit physically appears highly integrated into the product. As of 2013, almost all printer manufacturers offer multifunction printers ...

VueScan enables the user to modify and fine-tune the scanning parameters. The program uses its own independent method to interface with scanner hardware, and can support many older scanners under computer operating systems for which drivers are not available, allowing old scanners to be used with newer platforms that do not otherwise support them.
