Techopedia explains Imagesetter
An imagesetter is an ultra-high-resolution large-format computer output device, able to produce quality surpassing that of a typical home or office printer. The resolution of a home printer is generally up to 300 dots per inch (dpi), with an office printer having 600 dpi, whereas the dpi of an imagesetter is 1270, 2540 or up to 4000 dpi depending on the type. The color images by an imagesetter are high resolution because they are created by printing the same image four times upon each other, that is, once each in cyan, magenta, yellow and black (CMYK).
