Two dual-monitor digital audio workstations. Multi-monitor, also called multi-display and multi-head, is the use of multiple physical display devices, such as monitors, televisions, and projectors, in order to increase the area available for computer programs running on a single computer system.
HP Universal Print Driver (UPD) is an intelligent print driver that supports a broad range of HP print devices, such as LaserJet and various MFPs. Developed by Hewlett-Packard , HP UPD combines a general purpose driver ( XPSDrv , UniDrv , or PSCRIPT ), print control, and HP proprietary extensions.
In computers, a printer driver or a print processor is a piece of software on a computer that converts the data to be printed to a format that a printer can understand. The purpose of printer drivers is to allow applications to do printing without being aware of the technical details of each printer model.
Because it was hardware-compatible with CGA, the Paradise card did not need special software support or additional drivers. [ 43 ] Another extension in some CGA-compatible chipsets (including those in the Olivetti M24 / AT&T 6300, the DEC VAXmate , and some Compaq and Toshiba portables) is a doubled vertical resolution.
[6] [7] [8] Nominally, the Hercules card provides a horizontal scanning frequency of 18.425 ± 0.500 kHz and 50 Hz vertical. [9] It runs at two slightly different sets of frequencies depending on whether in text or graphics mode, providing a different vertical refresh rate and a different aspect ratio via a different pixel clock and number of ...
The exact difference between horizontal and diagonal dot pitch varies with the design of the monitor (see pixel geometry and widescreen), but a typical entry-level 0.28 mm (diagonal) monitor has a horizontal pitch of 0.24 or 0.25 mm, and a good quality 0.26 mm (diagonal) unit has a horizontal pitch of 0.22 mm.
Duplex printing is a feature of some computer printers and multi-function printers (MFPs) that allows the printing of a sheet of paper on both sides automatically. Print devices without this capability can only print on a single side of paper, sometimes called single-sided printing or simplex printing.
The vertical orientation allows greater detail along the vertical axis while conserving detail on the sides. Although the early Vectrex home console had a built-in, vertically-oriented screen, the majority of home games consoles were designed to interface with standard television sets, which use landscape orientation.
