Basic method of Operation Inkjet printers create text and images by spraying ink through microscopic nozzles in the print-head onto the paper. Bubble jet printers work on the same principle as the thermal printer. It relies on the inherent phenomenon of the Piezo crystal. An electric charge is passed across the crystal which produces a pumping action, forming and ejecting ink-droplets. Basic method of Operation - Thermal Thermal inkjet technology relies on a different process.
Ink is held in the nozzle of the printer until it is required to fire an ink-droplet.
When this happens a small electric heater in the nozzle is switched on to start a heating process. This causes a bubble to form in the nozzle which forces the ink-droplet out of the nozzle. Because of their low cost and ease of use the inkjet printers will meet the needs of home and office. Inkjet printers are often used by graphic artists, designers and professional photographers who use digital photography. Inkjet printers can be used where quality colour printing is required.
