2D imaging scanners are capable of reading barcodes from a screen, but standard 1D scanners cannot. Technically, the lasers used in standard 1D barcode scanners read the light reflected off a barcode label to process its information, and are therefore unable to read anything from a computer screen. 2D imaging scanners, however, work by capturing and analyzing a picture of the barcode to decode its information. Because of this, they are capable of reading barcodes from a screen.
