In printing, DPI (dots per inch) refers to the output resolution of a printer or imagesetter, and PPI (pixels per inch) refers to the input resolution of a photograph or image. DPI refers to the physical dot density of an image when it is reproduced as a real physical entity, for example printed onto paper. [4]
ImageWriter LQ (Letter Quality) is a 27-pin dot matrix printer introduced in 1987 by Apple Computer, Inc. The print quality was comparable to competing 24-pin dot-matrix printers, and offered graphics at 320 × 216 DPI. Guaranteed compatibility with both Apple II and Mac computers made it popular in schools. [citation needed]
The term dot matrix printer is used for impact printers that use a matrix of small pins to transfer ink to the page.
