Have you ever wondered, what is a color laser printer? This question is one that comes with numerous different complexities since a color laser printer is an incredibly complex piece of technology.
Nevertheless, today, we’ll be looking at some of the key things you need to know about what a color laser printer is and how it works; hopefully, this may help inform your decision about the most suitable type of printer for your needs.
What is a color laser printer? Color laser printers use internal lasers to project images of the desired print onto a drum, which allows the printer to develop a final image based on positive and negative charges.
This unique form of printing technology was developed in the 1970s by Xerox and has rapidly become one of the most popular solutions for commercial printing overall.

How a Laser Printer Works
Laser printer technology can often seem somewhat misleading since it’s not the lasers directly that control the final print.
In fact, laser technology is only the first step in the printing process; thereafter, toner application to the paper is achieved through positive and negative charges, as we have briefly summarized.
1. Projection of an Image
After receiving a print request, the first stage in the process is for the laser printer to project an image onto the internal drum.
The printer achieves this through the use of lasers, which directly display the image on the drum.
2. Charge Alteration
At rest, the internal drum is positively charged. However, when the laser is applied to the drum, it becomes negatively charged.
This is a vital step during the printing process since the toner has a positive charge as standard.
While it will adhere to surfaces with a negative charge (as marked by the laser), it will not adhere to any positively-charged areas of the drum’s surface.
3. Attraction of the Toner Powder to the Drum
The third step in the laser printing process involves the toner adhering to the surface of the drum through opposite charges. Indeed, you may remember from childhood physics and chemistry that opposites attract while similar charges repel.
This concept is at play during the laser printing process since only the negatively-charged regions of the internal drum (marked by the laser) will be attractive to the positively charged toner.
Meanwhile, unmarked, positively charged areas on the surface of the drum will repel toner, preventing it from adhering to the surface.
The drum rotates continually against a developer roll, which is also negatively charged. As such, the developer roll will pick up any loosely adhered toner particles, providing a direct image on the developer roll’s surface as well.
4. Application to Paper
At this point during the printing process, the laser printer applies a negative charge to a sheet of paper before feeding the paper below the developer roll.
The contact between the developer roll and the paper, both of which have a negative charge, results in toner adhering to the negatively charged paper as powder particles; this will form the main image of the final print.
At this stage, the toner is still in powder form and must be fused with the paper before fully printing it.
However, the paper still holds a negative charge and could give users an electric shock if printed in the current state. As such, the paper is neutralized before being exposed to the fuser.
The fuser generates a lot of heat to melt the toner onto the paper’s surface, giving a strong adhesion between the paper and the ink.

6. System Restoration
At this point, the laser printer needs to restore itself to its previous state. To this end, the printer applies AC or DC bias to restore the internal drum’s positive charge.
A soft plastic brush removes any excess toner from the surface of the drum (which the printer collects in the waste toner reservoir).
7. The Process Repeats
Once the printer has completed the first color – usually black – it will have developed a monochrome image. However, to print in color, it must repeat the process for each of the four different colors.
After all four colors have been printed, all that’s left to do is deliver the paper to the waiting operator.
The printed paper is expelled moments after the fuser has melted the final toner ink color onto the paper; hence, laser printers often result in warm sheets of paper immediately after printing (but this will cool rapidly).
Then, the printer restores itself once more and is ready for any subsequent printing requests.

What is the Difference Between a Color and Monochrome Laser Printer?
With monochrome laser printers, only one color toner is applied to the paper – black – so the process only needs to be completed once.
However, with colored laser printers, the printer needs to cycle between all four colors: black, yellow, magenta, and cyan.
As such, once the printer has resent itself following the first toner application, the paper is fed back through to repeat the process with each subsequent color.
As a result, color laser printing takes four times as long as monochrome laser printing since the printer must go through the same steps four times.

What is Better: A Color Laser Printer or A Color Inkjet Printer?
Both color laser printers and color inkjet printers offer exceptionally high performance. As a result of this, it’s tough to compare the two printer models.
However, each has its specialty, as we’ve outlined below. As a quick summary, though, it’s worth considering the following points:
- For large-scale, long-term use, color laser printers often provide superior durability and far greater printing efficiency compared to color inkjet printers.
- Color inkjet printers may be more affordable to buy and run for small-scale use, delivering higher-quality color prints. However, this takes substantially longer, with far more significant risks of the printer malfunctioning due to its larger number of moving parts.

The Benefits of Color Laser Printers
If you operate a commercial property, school, or business, a color laser printer might be just the solution you need.
Indeed, color laser printers are powerful, fast, and effective, making them incredibly valuable for large-scale printing requirements.
Although a color laser printer is significantly (four times) slower than a color inkjet printer, it is still worth considering that it can deliver effective, rapid results.
Of course, this depends on the amount of color being applied, but most modern commercial color laser printers can easily handle around 20 pages per minute or more.
Color laser printers are also substantially more durable than most inkjet printers since there are far fewer small, individual moving parts to go wrong.
This fact means that color laser printers often need much less maintenance to continue operating as expected; moreover, color laser printers are also often longer living, providing years of reliable service.
The Benefits of Color Inkjet Printers
At this point, we’ve considered some of the key benefits of color laser printers – but what about color inkjet printers?
While color laser printers are often a little rarer than monochrome laser printers these days (due to their slower performance), color inkjet printers are often an incredibly popular choice for homeowners and lower-scale printing needs.
What’s more, many color inkjet printers can deliver roughly the same speed for both monochrome and colored prints since they rely on internal nozzles to dispense minute amounts of ink rather than a laser.
If you’re looking for a premium-quality printout, color inkjet printers might be just the way to go. They typically deliver a far superior quality print due to their high-quality, ultra-precise ink application.
Moreover, they are often much cheaper to buy, thanks to the simpler technology utilized within a standard inkjet printer.
Oddly, despite the drastically simpler technology in inkjet printers, the time difference between developing inkjet and laser printers was actually quite small – only around a decade or so!
However, the affordability of inkjet printers has arguably spurred them to a greater market for residential users – but they may be less suited to business applications.
As such, if you’ve been looking to print photos or exceptionally detailed designs, a colored inkjet printer may be more viable.
However, they are also substantially slower than even color laser printers, let alone monochrome laser printers; if you’re looking for efficiency, try a laser printer instead.
