Single unit HP inkjet printhead

Hewlett-Packard is introducing new technology in inkjet printers that it hopes will help fend off rivals. The company said it is using a new photolithographic process to create inkjet printheads as a single unit, instead of welding different components together. This manufacturing shift is designed to better align the chamber, nozzles and heating element and, in turn, to improve accuracy of ink drop placement. The new printheads can also support at least 3,900 nozzles. The higher nozzle density and greater accuracy in dot placement yield faster and better quality prints. With the new product, HP said, it can increase the area the printhead covers with each pass over a page and thus can reduce the amount of time needed to print a page. The increase in the number of nozzles also translates into more available colors.
