The task is easy and simple in theory, however, one small error of the DTP operator and the circulation of several thousand copies of newspapers can be thrown away.
In this work, many things may go wrong: change of paper for another, new printer with other inks, incorrect conversion of colors.
There are also typo errors, bad placement of some element or just a few details.
All this can end very badly and bring big losses - so it's work under stress and tension, because if something goes wrong it usually will be just for the DTP operator.
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
Bargain sale of printer accessoriesPrinter accessories can be purchased at reduced prices when they are covered by rebates.
It must be admitted that people who already use printers already know very well in which stores they can buy cheaper accessories that have the same good quality as their most expensive counterparts.Very often, the prices of their purchase have been reduced because the owners of particular stores wanted to sell a new type of accessories or increase the level of sales of goods brought by them.Of course, they try to lower the prices of those products that have a chance for the highest sales, which is why they introduce rebates on inks and toners as well as photocopying and cleaning materials. .
