Difference Between Inkjet and Deskjet

Printers have become some of the most common electronic devices used in everyday lives. As documentation and paperwork are a crucial part of any type of job setting, printers and photocopying instruments are also required when working in an office environment. Different technologies are used for printing and accordingly different types of printers are available in the market.

Inkjet vs Deskjet

The main difference between Inkjet and Deskjet is that Inkjet is a specific category of printer that uses the Inkjet technology to print photos and documents onto paper. Deskjet on the other hand is a brand of printers manufactured and marketed by HP. Deskjets are proprietary printers made and sold only by HP.

INKJET vs DESKJET

Inkjet is a type of printer that uses inkjet technology for printing. The technology was first developed in 1970, by Epson, Hewlett-Packard, and Canon. Since then the technology has been adopted by different companies for manufacturing printers. This category of printers uses printheads that eject small droplets of ink to the sheet surface.

Deskjet is the brand of printers that are manufactured and marketed by HP. These are a variant of the Inkjet category of printers and use the same technology as other Inkjet printers. The Inkjet technology was further refined by Hewlett-Packard for application in the Deskjet products, but the operation is based on the same principle.

What is Inkjet?

Inkjet is a category of printers that work on Inkjet technology. The concept for the technology was first developed in the late 1950s, which was then developed and produced by Epson, Hewlett-Packard, and Canon in the 1970s.

The technology works on thermal ink for printing on the surface of sheets. Thus a special type of ink must be used for printing with this type of printer.

The Inkjet technology uses printheads to eject small droplets of ink on the surface to be printed on. The printhead consists of small microscopic nozzles that eject the ink in the form of a stream directly onto the sheet surface.

High pressure is used to eject the stream of ink, thus a pump is fitted on the nozzles for creating the stream. As the ink used is heat-activated, it is first heated before being sprayed.

The nozzles can be made of two types, Continuous nozzles and Drop on Demand nozzles. Both the nozzles eject ink at different times and thus, different quantities of ink are ejected.

The Inkjet printers are relatively cheaper than Laser printers and they also take up less space, as they do not have as many working parts as Laser printers and thus are more compact.

What is Deskjet?

Deskjet is the brand of printers manufactured and marketed by HP. These printers work on the same principle of Inkjet technology, by using thermal ink to print. But the technology has been refined by Hp for use in their printers to increase the printing speed.

Inkjet technology was developed by Hp in 1970, along with Canon and Epson. The technology uses species thermal ink to print on the surface of sheets. 

Heated ink is sprayed in the form of a stream on the surface of the sheet. The stream is ejected through a set of the microscopic nozzle under pressure from a small pump placed above the nozzle.

Thus droplets of ink are dispersed to create an image of the printing material on the sheet. The first Deskjet printer was introduced in 1988 and it had a print rate of only 2 pages per minute.

Later on faster and more efficient printers were manufactured that could print more pages while keeping the amount of ink dispersed to a minimum to save on ink.

Deskjet printers require HP ink cartridges to operate and thus cannot work on other types of ink cartridges. Thus although Deskjet printers are cheaper than Laser printers, the cartridges required are expensive, increasing the cost of maintenance.

Main Differences Between Inkjet and Deskjet

  1. Inkjet is a category of printers that operate on the Inkjet technology, whereas Deskjet is a brand of printers manufactured and marketed by HP
  2. Injet was developed in 1970 by HP, Epson and Canon. The first Deskjet was made by HP in 1988
  3. Inkjet uses printheads to eject small droplets of ink on the print surface. Deskjet uses a refined version of Inkjet to increase printing speed
  4. Inkjet printers use thermal heat activated ink for printing. Hp Deskjets can only work with HP ink cartridges
  5. The only drawback with Inkjet printers is that the ink is expensive. Deskjet printers are slower than Officejet printers and as they do not work using other cartridges, the maintenance cost is high.

Conclusion

Over the years, printers have become as important in a work environment as pens, computers, laptops, and so on. As documentation is an important part of office work, almost all kinds of office environments require printers.

Both Inkjet and Deskjet are the same type of printers, as Deskjet is a brand of Inkjet printers manufactured by HP. Thus both these printers use the same technology for printing.

Both these printers have the same drawbacks, they are relatively slower than Laser Printers and the ink cartridges required in these printers are very expensive. 

Regardless of these drawbacks, both these printers are very commonly found in office and bureaucratic settings, as they don’t require much maintenance and are very compact compared to Laser printers.
