These printers are the most common type of printers that are available in households. They are usually small in size and can range in prices, depending on the company and the functions it can perform.
More expensive models might also come with copy, fax and scan functions. The concept of inkjet printing was developed in the 19 th century, with the printer technology being developed in the late s.
Printers that could render digital images generated by computers were developed in the s by Epson, Hewlett-Packard and Canon. The inkjet printer works in a complicated way. It has a series of microscopic nozzles that spray a stream of ink directly onto the paper. The nozzles either have a high pressure pump or tiny heating elements behind them that helps deposit ink on the paper.
In continuous technology, a high-pressure pump direct liquid ink from the cartridge through a gunbody and a microscopic nozzle, creating a continuous stream of ink droplets that are deposited on the paper. Extra unwanted ink is dropped into a gutter, which is recycled when the printer is active again. The thermal DOD uses a heating element to heat the ink in a chamber, which cools when applied to the paper. The piezoelectric DOD uses a piezoelectric material behind each nozzle instead of a heating element.
In DOD, the printer cartridges fires ink only at special points on the surface that is required for creating an image. Inkjet printers produce cheaper copies but prints slower compared to laser printers.
These are also small and compact, with the printer fitting right on the desk or workstation. The initial cost of these printers is quite cheap, but Officejet is usually more expensive than the basic model as it incorporates other features. Inkjet printers are honed for their ability to print good quality and sharp text and images and to print on almost any kind of paper. Advantages of an inkjet include quieter in operation, high print quality, no warm up time and low cost per page.
While, disadvantages are the ink is expensive cheaper alternates are available from third party cartridges , ink is not waterproof, the nozzle is prone to clogging and the ink dries up if not used for long periods of time. Deskjet is a brand of printers by Hewlett-Packard. Deskjet is created for home usage, which means there are more compact, have less features and are cheaper.
Deskjet printers are basic models and only offer printing capabilities. More features can be purchased with higher models, which cost extra. These printers also have slower printing speeds, with the highest Deskjet printer printing around 28 pages a minute. Laser printer is a type of printer that produces high quality text and graphics by passing a laser beam on plain paper.
This process uses a xerographic printing process, which uses a cylindrical drum coated with selenium to print an image. Laser printers are quite huge and bulky and require fast paper feeders.
HP DeskJets have a colorful design and are built to last. In addition to printing, scanning, and copying, an ENVY printer often also offers duplex printing and photo printing. Thanks to the high print resolution, special HP photo inks, and borderless printing functionality, you can easily print all your holiday photos and color prints. In addition, the ENVY has a useful color screen or touchscreen screen on which you can adjust your settings. The OfficeJet printers are, as you would expect, intended for the office.
An OfficeJet is an inkjet printer with an average print speed of 15 pages per minute, so it's especially suitable for a department with up to 3 people. The OfficeJet Pro is available for small offices with 4 to 5 employees. It's faster and has a larger input and output drawer. An OfficeJet Pro can almost always scan and copy. Some models also have an automatic document feeder, which allows you to scan or copy a stack of documents in one go. An HP LaserJet printer doesn't use ink, but toner cartridges to print.
These are cheaper than regular cartridges and you don't have to replace them as often. This makes a LaserJet very suitable in places where printing is very common, such as a medium-sized office or a school.
These printers have a high print speed, so you can print continuously. Many of these models come with useful options such as duplex printing or duplex scanning. The HP PageWide is designed for places where a lot of printing is done, like at a law firm or a multinational corporation. Deskjets are color inkjet printers for home use.
The top-of-range Deskjet can print, scan and copy and has wireless capability while the basic model is a single-function printer.
The range is constructed from 25 percent to 35 percent recycled materials and has a top print speed of under 10 pages per minute. The top model can also print directly from the Web without needing a computer and can produce two-sided printing automatically. Officejet printers are small enough to fit on a desktop and are intended for home offices, or smaller offices and businesses.
They can be used on basic networks with two or three users; some have wireless connectivity. The all-in-one models have fax capability and the fastest printer in the range can print at up to 16 pages per minute in black and nine ppm in color. Designed for a greater output, the Officejet Pro range can produce up to 1, pages per month at speeds of up to 20 pages per minute in black and 16 pages per minute in color.
