Basics of print advertising
Almost every company needs certain printed articles, or if you prefer printing. Leaflets, banners or posters are the main means of advertising for many companies, especially for local and small ones.
Well designed leaflets or business cards can attract many customers, and badly made to scare away and discourage our brand, company or product. Therefore, it is necessary to pay special attention to the quality of these materials, also in terms of technology of doing these things in the printing house.
Connecting printers with a scanner
Sales of printers with a scanner is now a very good way to run a profitable business. This is because these types of printers have many customers who want to own them in their homes or companies. Therefore, both small printers with an additional scanner and large scanning devices go on sale. They work perfectly in offices, schools, in the back of the shop or at universities. Therefore, it is not uncommon to sell printers with a scanner, and then you can order almost any number of such devices and they will be delivered almost instantly to the delivery address.
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.
