What is Laser Printer in Computer

Laser Printer 

An impact-free printer is a laser printer. Because it prints an entire page at once, it is often referred to as a page printer. This kind of printer transfers text and graphics onto paper using a concentrated laser beam. Laser technology is used by laser printers. Gary Starkweather created the laser printer initially at Xerox PARC. 

What is Laser Printer in Computer

A laser printer is a kind of printer that prints high-quality text and graphics on paper by using a laser beam. To transfer the toner onto the paper, it uses a hot fuser in conjunction with electrostatically charged toner. Laser printers are renowned for their dependability, crisp output, and quick print times.


Features of Laser Printer

There are benefits associated with each type of laser printer, so it's helpful to identify the qualities that are most significant to you. These are:

Printing wirelessly

No limits to the convenience that effortless connectivity brings. Look into any restrictions that may apply while connecting the printer to a Wi-Fi network. Thanks to developments in wireless printing technology and Wi-Fi connectivity, printing documents from your phone may now be done swiftly and efficiently.


Handling of Paper.

The skill to manage paper easily is essential in both residential and corporate settings to prevent traps and other technological problems. It's interesting to note that when searching to purchase the best printer, many customers forget to inquire about this feature.


Print Quickness 

The number of pages per minute your printer can produce is a significant factor in meeting office productivity standards. Select the ideal office laser printer for the volume of printing your business needs to avoid a printing suite constraint.


Volume per Month

Recognize each printer's monthly duty cycle before making a decision. You can prevent problems and technical repairs by being aware of how many pages the device can print consistently each month.


Components of Laser Printer

These laser printer parts have an impact on printing either directly or indirectly. Certain components are extra add-ons that improve a printer's performance. Below is an explanation of each of these elements:

1. Laser 

The laser beam is the most important component of a laser printer. A laser gun that continuously shoots light beams produces the laser beam. The system controller sends all of the printing-related data to the laser gun. 

2. Imaging Device 

The laser beam travels directly to the imaging equipment after being fired by the laser gun. The imaging unit's multiple sub-components are in charge of printing the laser data onto the paper.

3. Drum Unit OPC 

A mirror helps to focus the laser beam on the OPC drum unit. The organic photoconductor drum is coated in a photoconductive substance and constructed of metal. For the OPC drum to collect image data from laser beams, this layer is essential.

4. Cartridge and Toner 

Unlike liquid dye inks, the toner used in laser printers is in the powdered form. The various toner colors are stored in the toner cartridges. A developer roller that is positioned close to the OPC drum unit receives the toner directly. The toner is drawn to the OPC drum by the opposing charge and falls into the space kept between the OPC drum and the developer roller. With the development roller for each, the identical procedure took place.

5. Garbage Toner Container 

A waste toner bin's only function is to gather any leftover toner powder or layer. Since the bin collects all of the leftover toner from the printing process, it needs to be emptied periodically.

6. Microchip Electronic

Toner cartridges for certain laser printer models have electrical chips. This chip's job is to keep track of how much toner is required for printing. To avoid wasting, it sends a signal to the cartridge to release a predetermined amount of toner.

7. Rollers or a Transfer Belt

The earlier models of laser printers employed transfer belts. To print the necessary data, they were utilized to move the paper through the toner area. These belts provide the paper with end-to-end support for easier handling.

8. Rollers for feeding 

Paper is transferred from an input tray to a printer's printing components via feed rollers. Additionally, the printer's internal rollers are positioned to ensure that paper passes through all of its sections smoothly. Paper jams can result from minor damage, so these rollers need to be inspected often. 

9. Command Console 

An essential component of the user interface is the control panel. It provides access to several printing-related parameters. The control panel may have function keys in addition to a color touchscreen or a straightforward monochrome display. The printing process begins with each command entered through the control panel.

10. Tray of Paper 

One essential tool for managing the papers is a paper tray. These papers are stored in two different types of paper trays. Before being sent for printing, the raw paper is kept in the input paper tray. All of the printed sheets are collected and stored on the output paper. From model to model, the capacity for both trays varies. 

11. A scanner that uses optics 

In addition to printing, some laser printers provide scanning capabilities. The printer is equipped with an optical scanner to record the information on the page or document. The text, numbers, characters, graphics, and other content on the input paper are scanned by the scanners using light beams.


Advantages of Laser Printer

  • It doesn't make a sound. 
  • It operates at a rapid rate. 
  • Running a laser printer is inexpensive. 
  • Printing both text and photos is possible. 
  • The most suitable printing technology is a laser.


Disadvantages of Laser Printer

  • The cost of a laser printer is high. 
  • It is unable to print numerous copies at once. 
  • Printers with lasers are not cheap.
  • Toners are bad for people. 
  • It will release ozone and pollute the environment.
