Cheap or expensive?
The models we're taking a look at in this article, are generally found on the bottom of the program of the manufacturers. This doesn't necessarily mean that they don't perform well, however the differences with the more luxurious class are quite large. More more generally nets you much higher print speeds, which are very useful in a professional environment. If you're a student that has to write kilos worth of reports, an older, but also once more expensive second-hand laser printer could be a smart investment.
If you print a lot you'll run into another problem with the tested models. They all have relatively small paper trays on board. Consequently, a pack of paper will always have to be divided. Quite unpractical, especially if you have to store the rest of the paper somewhere else. More expensive models allow you to store exactly 500 sheets of A4 paper in the tray.
Another difference is found in the feature sets. More expensive models can for example mail a scanned document directly for you or they can work with Cloud services such as Dropbox and OneDrive. They also offer more features in regards to controlling the device. In this class the displays of the tested models are simple LCDs, however the more luxurious models feature nice colour displays with touch. If you don't need any extensive features, you can save some money by considering these simpler models. This is because the base is not that different in principle, the sharpness of the prints is not necessarily worse in the entry-level segment.
However, a cheap buy might turn out to be expensive in the long run. The price per print varies a lot, as we will see further down the article. Do read the entire article, before purchasing a device.
