A couple of decades ago, you would be considered technologically advanced if you had a computer at home. Kids would proudly show off their PCs to their friends who would look at it like a being from another planet! However, technology has advanced fast and quick and having a PC at home is as common as having a television set today. In fact, most homes also have additional hardware like microphones, webcams, scanners and printers, that would earlier have been found only at organizations and internet cafes.
You could get to know a whole lot of direct information on printers from websites like topdogg.com that give you a heads up on all the technical advancements in the field of computer hardware. Printers have advanced a lot since the days of the Dot Matrix printers that were mainly used to print bills and invoices! The most commonly used printers today are the Inkjet printers and the Laser Printers. Inkjet printers use cartridges to make tiny dots about 50 microns in size to create an image on paper. The printer uses black ink cartridge for printing black and white. However, if you have a color printer, it will have additional slots for a color cartridge.
Laser Printers, on the other hand, use a toner filled with powdered colored plastic that it sprays onto the papers and uses electricity to melt it. As with Inkjet printers, these too have options of having a black toner and a color toner. Laser printers are generally more expensive but make prints faster and of a higher quality than Inkjets. Thats why Inkjets are usually meant for home use and Lasers for commercial purposes.
