In Traditional Mode, HP UPD is bound to a print queue and behaves like a normal printer driver with the addition of bi-directional communications for device queries and real time print job status. This mode can be chosen during driver installation, or on the dynamic mode universal printing dialog box.
Alexander Murray and Richard Morse invented and patented the first analog color scanner at Eastman Kodak in 1937. Intended for color separation at printing presses, their machine was an analog drum scanner that imaged a color transparency mounted in the drum, with a light source placed underneath the film, and three photocells with red, green, and blue color filters reading each spot on the ...
A port scan or portscan is a process that sends client requests to a range of server port addresses on a host, with the goal of finding an active port; this is not a nefarious process in and of itself. [1] The majority of uses of a port scan are not attacks, but rather simple probes to determine services available on a remote machine.
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.
(keyboard/printer) A computer terminal is an electronic or electromechanical hardware device that can be used for entering data into, and transcribing [1] data from, a computer or a computing system.

By the mid-1990s, Adobe would either develop or acquire Photoshop from John and Thomas Knoll , FrameMaker from Frame Technology Corporation, and After Effects and PageMaker from Aldus , as well as develop Adobe ...
The network controller implements the electronic circuitry required to communicate using a specific physical layer and data link layer standard such as Ethernet or Wi-Fi. [a] This provides a base for a full network protocol stack, allowing communication among computers on the same local area network (LAN) and large-scale network communications through routable protocols, such as Internet ...
