Sample components (WINDEV): WD Photocopier
[ + ] The Photocopier component enables you to photocopy documents via a scanner and a printer. The scanner must be Twain-compatible in order for the component to operate. This component can be used in two modes: - With an interface used to define some parameters such as the lightness or the number of copies. - Without interface. The parameters of the computer will be used by default. You also have the ability to pass custom parameters
