Many offices and homes prefer this one than an inkjet, another popular printer type, as it can churn out pages at a much faster rate.
Commercial ones can yield as much as 200 pages a minute for black and white prints.
For color print jobs, they can produce up to 100 pages a minute.
The way it works is unlike an inkjet.
That's because the printing technology it uses doesn't make it directly deposit ink on the paper's surface.
Instead, laser is used to project the entire image onto a drum inside it.
This drum is electrically charged and attracts a dry type of ink called a toner.
The sheet of paper rolls over the drum, and the toner it has is fused onto the paper by means of heat.
With an inkjet, the image is printed one line at a time.
And this is the reason why its output speed is much slower.
But with a laser type of printer, the page is ejected from the unit completely finished.
Additionally, it's much possible to attain sharper details.
It's for this reason why many offices go for it for coming up with professional-looking documents.
There are several different things to put into consideration when shopping for one.
First, you have to decide whether you want to go for a monochrome unit, or something which can also print in color.
Bear in mind the kind of documents you're going to need most of the time.
If you primarily require black and white documents, then a monochrome model will suffice.
Otherwise, paying extra for color printing capability is a sound investment.
One of the expenses you need to worry about with this kind of machine is replacing the toner cartridges.
When they run low or out on toner, of course they need to be replaced with pre-filled ones.
Some models combine the toner cartridges and drum in a single system; replacing one means you need to replace the other as well.
But some units got these two into separate units.
Different models can handle different media types and sizes.
Consider the kind of media you will frequently have to print on.
Some inexpensive ones are limited to working with standard-size media.
On the other hand, some with steeper price tags are compatible to work with a variety of media.
For such, it's important that you read the product's specification.
The resolution is another role player when it comes to choosing the right unit for your needs.
Expressed in DPI or dots per inch, the resolution is much better with a higher number.
For instance, a 600 x 600 DPI unit is good enough for everyday document printing tasks.
But something with a 1200 x 1200 DPI or even 2400 x 2400 DPI is recommendable if you need to print documents that contain graphics.
A laser printer with an expandable RAM or memory is much better than with a fixed one.
Such will determine the speed of the unit's performance, as complicated tasks require a fairly large amount of memory.
The unit's connectivity options should also be taken into consideration.
Some units can be connected to a single computer at a time, while there are those which can be connected to a network.
