Inkjet printers are not all that complicated. Though different manufacturers have different ways to control the process, ink jets work by spraying tiny drops of ink on to paper. The shapes of the print nozzle, the size and the number of drops and the way the ink is heated vary, but the printing technology is similar.

Laser printer work like a typical photocopier. Light from a laser draws an image on a photosensitive drum, which takes on an electirical charge where the laser hits. Plastic toner particles stick on the charges areas and then transferred on to the sheet of paper. The paper passes through the fusers, where heat and pressure melt the toner on to the surface of the paper. The whole process is very fast, simple and efficient

The design differences between lasers and ink-jets have an important effect on the cost. Most users focus on purchase price while shopping ignoring the running cost. A laser printer will cost you 20 to 30 paise per page for a typical business letter inclusive of all consumables : tonner, drums and developer. The same page on the inkjet averages 40 to 50 paise or more. More over colour printing is more expensive than black printing though it provides colourful family fun. Keep in mind that some ink jets have one colour catridge for three colour i.e:, cyan,magenta, yellow. In short the Inkjets costs you more per page and the more you print the more expensive it gets but you have a wide choice over colour management

On the other hand in case just letter printing or black printing is to be done laser come handy reducing the running cost but takes your advantage over colour.
