Laser printers are the most expensive type of printer in terms of running costs, due to the cost of the toner cartridges. But the cost per page for black and white printing is usually less than for inkjet printers.
The toner is the same type of toner used in photocopiers. And laser printers emulate the final stage of what a photocopier does by using a statically charged drum to attach toner to the paper. No liquid ink is used. The powdered toner is statically stuck to the paper when it passes over the rollers, and is then very quickly heated to fuse it to the page. The laser market is predominantly black and white, as nearly all businesses use the technology to produce cost-effective printouts. Laser printers ability to produce crisp, exact quality for text makes it the best choice for printing most corporate documents.
Laser printers are now quite capable in printing graphics as well. But for clear, color printing, color laser printers are ideal. And as their prices continue to decline, they are becoming more popular. But, again as with color inkjet printing, the cost per page goesup dramatically with color laser printers because they use 3 or 4 toner cartridges.
