Parallel interface An interface that transmits multiple bits simultaneously (usually in one-byte segments). Your printer has a built-in, Centronics-type parallel interface with bi-directional capability. See also Interface. Platen Printer component that holds the paper in position during ink transfer. Print head The printing mechanism that contains print nozzles and ejects the ink for printing. Print head capping An automatic protection function that prevents the print head unit and BJ cartridges from drying out or becoming clogged with dust. Printable area The area of a sheet of paper on which a printer can reproduce text or graphics (the printing area is smaller than the paper). On this printer, the printing area varies depending on the type of paper being used. Printer driver Software that sends printing instructions to a printer. The printer driver keeps track of the attributes of a printer and the codes the program must send to access those attributes. RAM Random Access Memory. Printer memory that is used for temporary storage of information you want to print and downloaded fonts. Resolution The density of dots for any given output device. Expressed in terms of dots per inch (dpi). Low resolution causes font characters and graphics to have a jagged appearance. Higher resolution means smoother curves and angles as well as a better match to traditional typeface designs. Resolution values are represented by horizontal data and vertical data, for example, 360 × 360 dpi. This printer can produce output with resolutions up to 720 × 360 dpi precision. RGB An acronym for Red, Green, and Blue; the three primary colors used in the additive process to form a wide spectrum of colors. G-2 Glossary
