2. Laser printing - Wikipedia

   en.wikipedia.org/wiki/Laser_printing

   e. Laser printing is an electrostatic digital printing process. It produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back and forth over a negatively charged cylinder called a "drum" to define a differentially charged image. [1] The drum then selectively collects electrically charged ...

   en.wikipedia.org/wiki/Dots_per_inch

   Dots per inch. A close-up of the dots produced by an inkjet printer at draft quality. Actual size is approximately 1⁄4 by 1⁄4 inch (6 by 6 mm). Individual coloured droplets of ink are visible; this sample is about 150 DPI. Dots per inch (DPI, or dpi[1]) is a measure of spatial printing, video or image scanner dot density, in particular the ...

5. Resolution enhancement technology - Wikipedia

   en.wikipedia.org/wiki/Resolution_enhancement...

   Resolution enhancement technology ( RET) is a form of image processing technology used to manipulate dot characteristics popular among laser printer and inkjet printer manufacturers. Closely related RET techniques are also used in VLSI photolithography manufacturing technology, in particular in relation to 90 nanometre technology.

6. Printer (computing) - Wikipedia

   en.wikipedia.org/wiki/Printer_(computing)

   A laser printer rapidly produces high quality text and graphics. As with digital photocopiers and multifunction printers (MFPs), laser printers employ a xerographic printing process but differ from analog photocopiers in that the image is produced by the direct scanning of a laser beam across the printer's photoreceptor.
