Color laser printers create the output image on four rollers, one for each primary color, and heat powdered toner so it sticks to the page. The average color laser printer has several trays, each capable of holding several hundred sheets. Many have duplexing capabilities -- meaning they can print on both sides of the paper -- and can also staple your output.
We use a machine that gives good quality colour printing using laser technology from none other than Konica Minolta. It supports a size bigger than A3 and can even print banners. It can print on a variety of media like card, plastic, sticker, clear and more.
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. The drum then selectively collects electrically charged powdered ink (toner), and transfers the image to paper, which is then heated in order to permanently fuse the text, imagery, or both, to the paper. As with digital photocopiers, laser printers employ a xerographic printing process. Laser printing differs from traditional xerography as implemented in analog photocopiers in that in the latter, the image is formed by reflecting light off an existing document onto the exposed drum.
