What is a laser printer?
A laser printer is a prevalent office machine that can be used to print documents, photos, and other business records.
Laser printers are popular because they produce high-quality prints quickly.
The first laser printers were designed back in the 1970s by Xerox. They became available for consumers around 2010.
How does the laser printer work?
As I mentioned, it is hard to explain exactly how does a laser printer work. However, let’s go through with an overview of the printing process and how different parts of the laser printer work.
The laser printer uses a controlled beam of light to create an image on a rotating drum. The drum is prepared from aluminum and is coated with a photoconductive material. All this means is that the laser light can change it so that it’s either positively or negatively charged, depending on what’s needed.
A laser beam is shone onto the drum, which then produces an electric current along the surface. This current will either be positive or negative depending on what needs to happen for the image. The charged parts of the drum attract (or repel) ink particles carried in a liquid solution that sticks (or does not stick) to them based on their charge. The ink particles are then transferred to paper for printing!
a) Paper feeding into the printer
In a laser printer, you can place paper in a tray from which it will be automatically picked up and fed into the machine during printing. The tray will either be attached to the back or side of the computer or an external part connected through a USB port.
b) Different parts and it’s uses
The laser printer has many different parts which are used during the printing process. Here are some of them:
Control panel: A control panel that allows you to select options and check for errors.
Fuser: The fuser that uses heat and pressure to fuse ink particles to paper.
Printer drum: It receives an image from the laser beam so the image can be transferred to paper.
Transfer corona: One of the crucial parts of a laser printer is transfer corona that aligns the negatively charged ink particles with the drum for transferring an image.
Cleaning assembly: It is used to remove dirt and dust from the printer drum, which also prevents potential damage during future printing jobs.
Benefits of using a laser printer
Here are some of the main reasons why you should use a laser printer for your business.
a) Fast printing
Laser printers can print quickly, which is helpful for high-volume printing jobs or sending documents to many different people. The first models could print about 300 pages per minute! Nowadays, they can print up to 600 pages per minute.
b) Good quality prints
Laser printers produce high-quality prints when using different types of paper, so it’s perfect for printing presentations or other important documents that must be clear and easy to read. There are many kinds of laser printers with varying resolutions, which will impact the print quality. Generally, higher resolutions will lead to more dots on the paper, which can be used to create a more detailed print.
c) Affordable price
Laser printers cost between $200 and $800, depending on their features. This is much cheaper than some other office printers, such as color inkjet printers that start at about $100 but require expensive printer cartridges that need to be replaced frequently.
d) No warm-up time
Laser printers don’t need to heat up before they start printing as some older inkjet models do. This means you can print more quickly and use it for many different jobs without waiting around.
Drawbacks of using a laser printer
While laser printers are mostly beneficial for businesses and homes, there are some drawbacks to using them too.
a) They can be noisy when in use
Laser printers operate at very fast speeds and create noise while printing. This might disturb other people who are in the same room as you, especially if you’re making lots of copies or need to print something urgently!
b) They can also be expensive
Laser printers will cost you a lot more than an inkjet printer, but the initial price of laser printers has dropped significantly over time. Nowadays, there are even small and portable wireless printers that only cost $200.
c) The prints aren’t as durable as with an inkjet printer
The prints are not as durable when using a laser printer, especially if you are using cheap paper. The inks can rub off easily, but depending on how often you need to use your printer, this might or might not be a problem for most people.
What are the difference between a laser and inkjet printer?
Although laser printers are similar to inkjet printers, there are differences between them. Here are some examples:
a) Laser printers have only black toner cartridges that can print around 6,600 pages. However, an ink cartridge in an inkjet printer has three separate colors, which need to replace one at a time when they run out of ink.
b) Laser printers use a laser beam, but inkjet printers use ink cartridges that contain liquid.
c) Laser printers don’t print as quickly as inkjet printers and need more time to warm up before they start printing.
Alternative to laser printers
Although laser printers are great for printing documents in high volumes, inkjet printers are cheaper and better when you need to print in color.
The 3D printer is another alternative that allows the user to print in 3 dimensions, but they’re also more expensive than office printers. Also, it takes a lot longer time to complete a print job.
Disadvantages of alternative to laser printers
Although the 3D printer can be considered an alternative for laser printers, there are some drawbacks.
They’re expensive and cost around $800 and above depending on their features. The small price of a laser printer is much cheaper than 3-dimensional printers that start at about $20,000! Also, you will need somewhere to keep and store the printer in your office.
Printing a 3D object can take several hours or even days, depending on the object’s size you want to print. A laser printer will print much quicker than a 3D printer, and they often require less maintenance too.
c) Require a lot of space
This type of printer will take up a lot of space in your office and at home if you choose to keep it there. Laser printers are much more compact, and they can be placed almost anywhere without taking up too much space.
d) They’re not as precise as laser printers
Although 3D printers can print objects in very fine detail, they will not be as good as a laser printer.
This article is about the Step by step process of how does a laser printer work. Laser printers are great for high-volume printing requirements and can print up to 6,600 pages in black-and-white. However, laser printers also have some drawbacks depending on your needs. For example, inkjet printers are cheaper, but they’re not suitable for heavy-duty work requiring many volumes.
There are even 3D printers that are more expensive but can print three-dimensional objects. However, they’re not as good as laser printers when speed is required, and taking up space is also another issue you will need to consider, especially if you only have a small workspace.
