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
Ink printer buy
Who today does not have a printer at home. Their prices are becoming more affordable and operating costs lower. Multifunction devices offer increasingly larger scanning resolutions, less margin, larger formats, etc.
But still, such home printers are far behind the professional equipment used in professional printers. Not to mention the much larger range of techniques used, which have nothing to do with those we know from home printers.
Printed roll, solvent, water, anhydrous - long to exchange.
The quality of such printouts is higher, which entails the obvious higher costs of printing itself.
It's worth repairing 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,.
