Computer accessories Printer HP Deskjet and Laserjet
There are several different types of printers in use today. They include 3D printers, dot matrix, inkjet printers, laser printers, and thermal printers.
For general purpose computing, the two main types of printers are the laserjet and the deskjet. Here we focus on HP, Hewlett-Packard, printers because they are generally very reliable. HP came out with the low cost laser printer in 1984, the HP Laserjet printer. Their operation is similar to the photocopy machine. The deskjet on the other hand uses a jet of black or multicolored ink to spray the text or image on the paper. The first ink sprayed printer, the inkjet was introduced by HP, the Thinkjet, in 1984.
