Numerous technologies have been introduced within a shorter time that can produce great results. No doubt, technology has made our life easier and simpler. Along with that, the technology is used in printers for better results. Printers aren't always created together. Printers use a variety of technologies, each with its own set of advantages and disadvantages, for both household and commercial use. Inkjet and laser printers are the two primary styles of printers that most people are familiar with. The third form, which we'll look at today, is the LED printer, which is less well-known.
Want to know in detail about LED printer and its working? Read this post carefully.
What do you mean by LED printer?
Typically, LED printers are the replica of laser printers with some additional benefits. These printers are quite similar to laser printers and use a light-emitting diode as compared with laser printers in the printhead.
The first LED Printers was introduced by the OKI company back in 1990 and then Casio came into the race. It works by concentrating light around the entire length of the drum, creating less charged areas that attract toner.
The printer next transmits the ink toner from the drum to the paper. Due to less demand, LED printers haven't become popular as inkjet and laserjet series printers.
Importance of LED Printers
LED printers are used frequently, but this series printer can produce efficient results. Due to their reliability and efficiency, LED printers are the best option than conventional printers. It has a quick response rate or print rates as compared with some of the laser design output. Compared with some other printers, LED printers are less costlier and productive.
Working of LED Printers
The working of LED printers is quite similar to laser printers it contains a photoreceptive drum with a surface and is effectively charged with a high-voltage static wire. The negative static charge in an LED printer, on the other hand, is generated by a strip of LEDs placed above or below the drum.
The pattern of light from the LEDs strikes the positive charges drum and erases the charge where it falls, leaving a negative charge in the picture of the page being printed. Positively charged powdered printer toner is then sprayed onto the drum, sticking where the LEDs have formed a negative charge.
When the paper reaches the printer's mechanism, it is positively charged by a separate high voltage cable, which absorbs toner from the negatively charged sections where it has stuck when it is forced past the printing drum. Until exiting the printer, the sheet of paper moves between two heated rollers, fusing the toner to the page.

Advantages and Disadvantages of LED Printers
- On principle faster than laser printers
- Requires less mechanical movement in comparison to laser printers
- Usually, less power is required compared to laser printers
- They're smoother because they don't need any components to move the image to the photoreceptive drum, unlike laser printers that require a rotating mirror. They can also be more lightweight due to the lack of moving pieces.
- They're more dependable because they don't have any moving parts that might crack over time. Printing is quicker since the negative charge on the photoreceptive drum is a generation in fewer steps.
LED printers save energy as compared to laser printers because LEDs are commonly known to be extremely energy-efficient. The drum life is shortened when used for frequent short jobs. Full speed potential is not immediately obvious unless used for high volume printing.
