The scanner is a device for the digitalisation of images and pictures. The data can be saved on the hard disk of the computer or a floppy disk. Depending on the model, the scanner is pluggend into the USB or parallel interface or a SCSI controller. After the driver is installed, image editing software such as Paint Shop Pro is able to adress the scanner with the command "import" or "aquire" and the scanned picture is loaded into the program.

Common are DIN A4 flatbed scanners, which are able to scan an entire DIN A4 page. Before that, hand-held scanners were used which covered only a small part of one page. They had to be pulled over the image in a straight way.
