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.
Good printing and design
Everyone likes when the leaflet is colorful, aesthetic and legible. However, a lot depends on the project itself, in other words, graphics preparing the files for printing. He must be aware of the basic matters regarding composition and layout. 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. A leaflet looks better on shiny and smooth paper than on a torn parchment. The type of paint and the method of printing is also not insignificant, and its selection is best entrusted to a specialist in this topic or to pass on a printing company that has extensive experience with each type of orders.
Who today does not have a printer at home. Their prices are becoming more affordable and operating costs lower. Multifunction devices offer increasingly larger scanning resolutions, less margin, larger formats, etc.
But still, such home printers are far behind the professional equipment used in professional printers. Not to mention the much larger range of techniques used, which have nothing to do with those we know from home printers. Printed roll, solvent, water, anhydrous - long to exchange. The quality of such printouts is higher, which entails the obvious higher costs of printing itself.
