Laser printing in Wikipedia
Laser printing is an electrostatic digital printing process. It produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back and forth over a negatively charged cylinder called a "drum" to define a differentially charged image.1 The drum then selectively collects electrically charged powdered ink (toner), and transfers the image to paper, which is then heated in order to permanently fuse the text, imagery, or both.
As with digital photocopiers, laser printers employ a xerographic printing process.
However, laser printing differs from analog photocopiers in that the image is produced by the direct scanning of the medium across the printer's photoreceptor.
Will we wait for the times when printers, DTP operators and printing house owners will have to look for a new job?
This enables laser printing to copy images more quickly than most photocopiers.Źródło: https://en.wikipedia.org/wiki/Laser_printing
Changing print needs

Printing is needed, no one has doubts about it, but are they just as necessary as 20 years ago? This is a debatable issue, but certainly the market needs and consumer demand have changed a bit.
The production of marketing materials increased significantly - leaflets, banners, promotional leaflets, and advertisements - and decreased the production of books and magazines, mainly due to the popularization of the Internet.
Repair or buy a new one?Computer repair often pays off.
There are such failures that it is difficult to tell what really broke down.
One of the more common problems is that the computer or laptop does not turn on.
The cause can be almost anything - from trivial problems with the power supply, to serious defects on the motherboard.
That is why it is worth taking the equipment for service, because the fault can be trivial and inexpensive to repair.
Even if we do not have a guarantee anymore, but our computer still performs well, it's worth servicing,.
