A laser printer is a ordinary kind of computer printer that project top quality text and graphics on paper. Laser printers follow a xerographic printing course besides are different from the majority of photocopiers in that the figure is produced by directly scanning a laser beam across the printer's internal drum. The illuminator of the laser modifies the electrical charge on the drum wherever it hits. The drum is then rolled through a reservoir of toner, wich is taken up by the charged parts of the drum. At last, the toner is transported to the paper by a mix up of heat and pressure. This is also the method copy machines work.

One of the top features of laser printers is their resolution coming from 300 dpi at the low end to 1,200 dpi at the high end. Laser printers reproduce very nice quality print and are capable of printing an almost unlimited variety of fonts. So whats the reason to have a laser printer instead than a more low cost inkjet printer? The significant features of laser printers are speed, precision and economy. A laser could move very faster, so it can "write" with much bigger speed than an ink jet. And because the laser beam has an unvarying diameter, it could draw more precisely, without spilling any overflow ink.

Laser printers tend to be a lot more expensive than inkjet printers, yet it does not cost too much to keep them working -- toner powder is not expensive and lasts a long time, while you could use up overpriced ink cartridges very fast. This is for what reason offices commonly use a laser printer as their "work horse," their machine for printing long text files. In most models, this mechanical mastership is complemented by more advance processing efficiency. A typical laser-printer controller could serve everybody in a tiny off

I recommend that you buy a laser printer if you print a lot of work continually or you work in an office where is required to print everything, because you are going to save a lot of money on ink. The ink of the ordinary printers cost to much and its not necesary unless you require to print with color.
