In computing, a printer is a peripheral device which makes a persistent human-readable representation of graphics or text on paper.
The first commercial printers generally used mechanisms from electric typewriters and Teletype machines.
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
Well, because the mob was quite illiterate at the time.Then also such fiction was printed, meaning for the reading of the book.
Because you need to build brand awareness at the customer, i.e.
printing and marketing is an inseparable couple.
