Printing is needed, no one has doubts about it, but are they just as necessary as 20 years ago? This is a debatable issue, but certainly the market needs and consumer demand have changed a bit.
The production of marketing materials increased significantly - leaflets, banners, promotional leaflets, and advertisements - and decreased the production of books and magazines, mainly due to the popularization of the Internet. Will we wait for the times when printers, DTP operators and printing house owners will have to look for a new job?
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.
The specificity of color printouts lies in the fact that they must be made using the highest quality inks and toners. Otherwise, they will not make a good impression on customers coming to the photocopier and they will just quickly fade. Meanwhile, the use of colored inks often saves important tables or the most important statements appearing in books. Therefore, all people who make color prints want to use multi-colored inks that perfectly reproduce the color of the document to be printed. This is of course very important, but it is equally important to reach for suitable printer paper before making color prints.
