Wikipedia about laser printing
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.
This enables laser printing to copy images more quickly than most photocopiers.Źródło: https://en.wikipedia.org/wiki/Laser_printing
Short about printing The printing era has been pretty good since Gutenberg.
First, important things were printed like books. But these are REALLY important, not some literature for the mob.
Well, because the mob was quite illiterate at the time.
Then also such fiction was printed, meaning for the reading of the book.
Well, since the last 50 years (even hundreds of them), it's all about printing - books, leaflets, business cards, even shirts, mugs, pens ...
Well, really everything. Because you need to build brand awareness at the customer, i.e. printing and marketing is an inseparable couple.
Because you can print everything on your T-shirt and have it originally.
Well, who would prohibit the rich?
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,.
