These models spray tiny drops of ink onto a page to create an image. Output can be quite good on very smooth paper, but deteriorates on rougher stock.
Colors also tend to be vulnerable to smudging and running, particularly immediately after printing.
For busy offices, ink-jets are typically not fast enough, printing only 1 to 2 pages per minute. Laser Color laser printers use the same toner-based printing process as black and white laser printers, except that they combine four different toner colors. These models produce very crisp documents, with none of the smudging or wetness of a dense ink-jet page. Color laser printers can also be used as a regular black and white laser printer. Solid Ink Solid ink printers melt solid blocks of ink, which is then sprayed onto a page.
