Printers are increasingly improved each year. At the meantime, printers have reached approximately more than six different technologies such as inkjet printing, laser printing, solid ink printing, thermal printing, and 3D printing. My research will explain some of the technologies which are inkjet printing, laser printing, solid ink printing and 3D printing. First of all, inkjet printing will be detailed in three points which are the two technologies of inkjet printers, the advantages, what kind of ink it uses, and where it is usually used. Second, the paper examines how a laser printer works and where it is mostly consumed. Third, the paper explains the procedure of solid ink printing and the history of solid ink technology. Finally, the paper specifies what a 3D printing is and what differences between commercial and personal 3D printers are. At the end of my research a technique will be explained about accessing a printer from anywhere and anytime whether it’s from a cell phone or a work computer or laptop.

“A computer printer is a device that would allow a user to create a hardcopy of a document or image that is electronically created.”(Arkin, 2008) The market has variety of technologies focused on printers. There are two types of printer technology which are impact and non-impact printers. Impact printer is kind of undeveloped type, and there is one type that still exists in the market nowadays and is being used by customers which is the dot-matrix printer. The reason why an impact printer is considered as undeveloped is it’s limited in functions, it uses the same process that a typewriter uses which means the printer head must touch a ribbon and a paper, and lastly it’s quite noisy. The second type, the focus of this paper, is non-impact printers. A non-impact printer is a sophisticated type. It works smoothly and without having a printer head to touch a paper in order to transfer a text or an image. In addition, a non-impact printer uses a nozzle, heat, light or static energy. The first type of non-impact printer is inkjet printer. Generally, developed inkjet printers use one of the following technologies: continuous (CIJ), Drop-on-Demand (DOD). Continuous inkjet printing (CIJ) is supported by an ink pump that points ink from a tank to a tiny nozzle positioned on a gunbody. A crystal breaks the liquid into droplets that vibrates within the gunbody. After the droplets are electrostatically charged, some droplets are directed to their target on the print medium, and the others fall into a collection container for later re-use. Moreover, the first continuous inkjet printers were used in hospitals for making hard copies of medical strip chart recording. Continuous inkjet technology has three advantages: it prints in a high speed because the ink is ejected at such high velocity, the nozzle won’t be blocked up because it is always in use which saves time and reduces maintenance and the ink dries very quickly because it was mixed with alcohol and ketone solvents. Thermal Drop-on-Demand (DOD) inkjet printing is the technology that used in most consumers inkjet printers. In this technology, a print cartridge is used which contains tiny chambers, and a thermally induced pressure increases within the chamber which ejects a drop of ink out of the chamber. After that, a heating element evaporates the ink in the chamber causing a bubble to form, and as long as the chamber pressure increases, the chamber propels a droplet out. There is a relation between the ink cartridge, water-based pigment ink, volatile component, the vapor bubble and the ink. First of all, the ink cartridge is usually filled with a water-based pigment ink. Second, because a water-based pigment ink has a volatile component, it helps it to form the vapor bubble which makes the ink eject from the chamber. “The thermal inkjet principle was discovered by Canon engineer Ichiro Endo in...
