<Li> occasional color registration errors (mainly along the long axis of the page), which necessitate recalibrating the printer to account for slippage and drift in the paper feed system . </Li> <P> These disadvantages mean that, despite their marked superiority in producing good photographic and non-linear diagrammatic output, dye - sublimation printers remain niche products, and devices using higher resolution, lower color depth, and dither patterns remain the norm . </P> <P> This dithered printing process could require a region of four to six dots (measured across each side) in order to faithfully reproduce the color in a single pixel . An image that is 100 pixels wide may need to be 400 to 600 dots in width in the printed output; if a 100 × 100 - pixel image is to be printed in a one - inch square, the printer must be capable of 400 to 600 dots per inch to reproduce the image . Fittingly, 600 dpi (sometimes 720) is now the typical output resolution of entry - level laser printers and some utility inkjet printers, with 1200 / 1440 and 2400 / 2880 being common "high" resolutions . This contrasts with the 300 / 360 (or 240) dpi of early models, and the approximate 200 dpi of dot - matrix printers and fax machines, which gave faxed and computer - printed documents--especially those that made heavy use of graphics or colored block text--a characteristic "digitized" appearance, because of their coarse, obvious dither patterns, inaccurate colors, loss of clarity in photographs, and jagged ("aliased") edges on some text and line art . </P> <Table> <Tr> <Td> </Td> <Td> This section does not cite any sources .
