A laser printer is a common type of computer printer that rapidly produces high quality text and graphics on plain paper. The laser beam has an unvarying diameter it can draw more precisely, without spilling any excess ink.

This is why offices typically use a laser printer as their "work horse," their machine for printing long text documents. In most models, this mechanical efficiency is complemented by advanced processing efficiency. A typical laser-printer controller can serve everybody in a small office.

The main advantages of laser printers are speed, precision and economy. Laser printers tend to be more expensive than inkjet printers.

An inkjet printer is a type of computer printer that creates a digital image by spraying colored ink through nozzles. These nozzles are placed on cartridges, which are able to move quickly in order to target precise areas on the paper.

Inkjet printers are the most commonly used type of printer and range from small inexpensive consumer models to very large professional machines. Inkjet printers shoot thousands of tiny droplets of ink onto paper, creating images and text. Anyone can use the inkjet printer like students and employees of corporations.

Inkjet printers typically are smaller than laser jet printers, so they can save you valuable space. Inkjet printers usually have quieter operation than laser printers, which tend to be noisy. In a small office, both of these inkjet features are distinct advantages. The ink is often very expensive.

A dot matrix printer or impact matrix printer is a type of computer printer with a print head that runs back and forth, or in an up and down motion, on the page and prints by impact, striking an ink-soaked cloth ribbon against the paper, much like the print mechanism on a typewriter.

Dot matrix printer for the industry market are designed for high print speeds, high volume printing engineered, feed paths and custom configuration to help implement the business operation....
