Printing of images is very important for image processing, since the results of image processing are necessary to be given as visual images. This paper considers for printing of half-tone images by the NEC N7384-21 laser nonimpact-printer of ACOS computer system. The fixed-pattern methods, the dither methods and the extended dither methods are tested using GIRL and MOON SURFACE images in SIDBA. As results of evaluation, the fixed-pattern methods with dot-concentrated type are efficient for printing images of large size, and the dither and the extended dither methods with dot-concentrated threshold matrix are very convenient for printing images of small size, 27×27((mm)^2) or 54×54((mm)^2). It has been shown to be necessary to take the exponential (absorption) scale translation to get easy image output to see.
