Without it, printing would not be possible.Paper as a material has been known since 105, n.
E., That is for a very long time.
However, it was not until the twentieth century that more and more types of paper for various applications were invented. And now we have paper chalked, white, slippery, coated with plastics, etc.
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
A well-made leaflet will certainly have a better effect than a short, ugly one. A lot also depends on the printing house and the selection of paper and the type of printing.
