gppm
Short for graphics pages per minute, the speed with which laser printers can print nontext pages. Typically, laser printers are rated in terms of pages per minute (ppm ), but this refers only to the speed with which they print text pages. The gppm is always much less and may be the more important figure if you are using the printer to print graphics -intensive documents.

(n.) Refers to any computer device or program that makes a computer capable of displaying and manipulating pictures. The term also refers to the images themselves. For example, laser printers and plotters are graphics devices because they permit the computer to output pictures. A graphics monitor is a display monitor that can display pictures. A […]
- graphics accelerator
A type of video adapter that contains its own processor to boost performance levels. These processors are specialized for computing graphical transformations, so they achieve better results than the general-purpose CPU used by the computer. In addition, they free up the computer’s CPU to execute other commands while the graphics accelerator is handling graphics computations. […]
- graphics based
)Refers to software and hardware that treat objects on a display screen as bit maps or geometrical shapes rather than as characters. In contrast, character-based systems treat everything as ASCII or extended ASCII characters. All graphics software is by definition graphics based. Systems that manipulate text can also be graphics based; for example, desktop publishing […]
