Printers
1 Characteristics and capabilities
1.1 Printer capabilities and speed are factors to consider when selecting a printer. The speed of a printer is measured in pages per minute (ppm). Printer speed varies between makes and models. Speed is also affected by the complexity of the image and the quality desired by the user.
1.1.1 Color or black and white
1.1.1.1 A computer monitor produces colors through the additive mixing of dots that are displayed on the screen. The dots produce the color range using red, green, and blue (RGB) dots.
1.1.1.1.1 Quality
1.1.1.1.1.1 The quality of printing is measured in dots per inch (dpi). The larger the dpi number, the better the image resolution. When the resolution is higher, text and images are clearer.
1.1.1.1.1.1.1 Realiability
1.1.1.1.1.1.1.1 A printer should be reliable. Because so many types of printers are on the market, research the specifications of several printers before selecting one.
