computer printer using a laser beam that generates an image, then transfers it to paper electrostatically. Laser-printer output may be produced very fast, with quality that approaches that of typesetting.
a computer printer that generates an image by scanning a photoconductive drum with a laser beam and then transferring the image to paper by means of electrostatic toner. Laser printers provide high-quality output of text and graphics; they are quiet and run fast. Contrast dot-matrix printer; inkjet printer.
computer driven device that utilizes a laser beam to print forms, letters, and labels. Laser is an acronym for Light Amplification by Stimulated Emission of Radiation. Laser printers are high-speed, high-quality printers with unique flexibility as to combinations of type fonts and orientation of characters on the page. They can create personalized computer letters with a combination of type fonts such as boldface or italics, to highlight words or passages. With a laser printer, by rotating the printed image 90° or 180°, more forms can be printed on any given quantity of paper. Laser printing also allows for copy variations within a mailing without the expense of printing different continuous forms for each variation. The laser printer is fast because it creates an image in its entirety at once, in contrast to a line printer that prints one line at a time. This eliminates the need for line charges usually levied by printers for long letters.
