Unidrv
UniDrv (Universal Printer Driver or Unidriver) is a GDI-based Microsoft Windows universal printer driver and architecture for non- PostScript printers. It is used to simplify driver development of non-PostScript printers (also called Winprinters) for printer manufacturers. ''Unidrv'' allows the creation of a printer-specific minidriver in the form of a GPD (Generic Printer Description) file, similar to a PPD file, which is much simpler than kernel mode driver development. Unidrv was introduced in Windows 2000 and replaced the Raster Device Driver (RASDD) interface used in Windows NT 4.0 and earlier versions. Overview The concept behind Unidrv is that a complete printer driver need not be written by the hardware manufacturer; only a device-specific minidriver is required that uses the core printing functionality of the Unidrv engine. A minidriver can be a customization file, or a plug-in, that allows special rendering functions or customized UI options. Unidrv supports non- PostS ...

Font Substitution
Font substitution is the process of using one typeface in place of another when the intended typeface either is not available or does not contain glyphs for the required characters. Font substitution can be aided by: * classifying fonts into generic font families, such that for example a sans serif font is substituted by another sans serif font. * font substitutions defined in operating system's font configuration for concrete font names (font families), such that for example Arial font is substituted by metric-compatible font Liberation Sans or Nimbus Sans L. * font substitutions defined in application software's (e.g. text processor) font configuration for concrete font names. When font substitution is being used to find a replacement for an unavailable character, it can lead to inconsistent visual appearance as part of a word or sentence is displayed in one font and another part is displayed in the substituted font. A method to work around this problem is to display the entir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Printer Driver
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. Printer drivers should not be confused with print spoolers, which queue print jobs and send them successively to a printer. Printer drivers in different operating systems Unix and Unix-like Unix and other Unix-like systems such as Linux and OS X use CUPS (short for Common Unix Printing System), a modular printing system for Unix-like computer operating systems, which allows a computer to act as a print server. A computer running CUPS is a host that can accept print jobs from client computers, process them, and send them to the appropriate printer. Printer drivers are typically implemented as filters. They are usually named the ''front end'' of the printing system, while the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windows 2000
Windows 2000 is a major release of the Windows NT operating system developed by Microsoft and oriented towards businesses. It was the direct successor to Windows NT 4.0, and was Software release life cycle#Release to manufacturing (RTM), released to manufacturing on December 15, 1999, and was officially released to retail on February 17, 2000. It was Microsoft's business operating system until the introduction of Windows XP Professional in 2001. Windows 2000 introduced NTFS 3.0, Encrypting File System, as well as basic and dynamic disk storage. Support for people with disabilities was improved over Windows NT 4.0 with a number of new Assistive technology, assistive technologies, and Microsoft increased support for different languages and Locale (computer software), locale information. The Windows 2000 Server family has additional features, most notably the introduction of Active Directory, which in the years following became a widely used directory service in business environmen ...

Graphics Device Interface
The Graphics Device Interface (GDI) is a legacy component of Microsoft Windows responsible for representing graphical objects and transmitting them to output devices such as monitors and printers. Windows apps use Windows API to interact with GDI, for such tasks as drawing lines and curves, rendering fonts, and handling palettes. The Windows USER subsystem uses GDI to render such UI elements as window frames and menus. Other systems have components that are similar to GDI; for example: macOS has Quartz, and Linux has X Window System and Wayland (display server protocol). GDI's most significant advantages over more direct methods of accessing the hardware are perhaps its scaling capabilities and its abstract representation of target devices. Using GDI, it is possible to draw on multiple devices, such as a screen and a printer, and expect proper reproduction in each case. This capability is at the center of most "What You See Is What You Get" applications for Microsoft Windows. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inkjet
Inkjet printing is a type of computer printing that recreates a digital image by propelling droplets of ink onto paper and plastic substrates. Inkjet printers were the most commonly used type of printer in 2008, and range from small inexpensive consumer models to expensive professional machines. By 2019, laser printers outsold inkjet printers by nearly a 2:1 ratio, 9.6% vs 5.1% of all computer peripherals. The concept of inkjet printing originated in the 20th century, and the technology was first extensively developed in the early 1950s. While working at Canon in Japan, Ichiro Endo suggested the idea for a "Bubble jet" printer, while around the same time Jon Vaught at HP was developing a similar idea. In the late 1970s, inkjet printers that could reproduce digital images generated by computers were developed, mainly by Epson, Hewlett-Packard (HP) and Canon. In the worldwide consumer market, four manufacturers account for the majority of inkjet printer sales: Canon, HP, Epson ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windows Vista
Windows Vista is a major release of the Windows NT operating system developed by Microsoft. It was the direct successor to Windows XP, which was released five years before, at the time being the longest time span between successive releases of Microsoft Windows desktop operating systems. Software release life cycle#Release to manufacturing (RTM), Development was completed on November 8, 2006, and over the following three months, it was released in stages to computer hardware and software manufacturers, business customers and retail channels. On January 30, 2007, it was released internationally and was made available for purchase and download from the Windows Marketplace; it is the first release of Windows to be made available through a digital distribution platform. Features new to Windows Vista, New features of Windows Vista include an updated graphical user interface and Skin (computing), visual style dubbed Windows Aero, Aero, a new search component called Windows Search, red ...
