Online stores with printing devices
Many people like to buy printing equipment in stationary stores. They pay attention to the fact that going to a stationary store can immediately see the equipment they intend to buy and learn all its good and bad sides. However, also the use of online stores can be very interesting and successful due to the fact that all printers sold in them are accurately described and covered by special rebate campaigns.
This makes buying them very profitable and enjoyable.
In addition, on the Internet you can find special websites dedicated to printing.
There are also pages with tips for people who work at photocopying points or make a large number of private printouts.
Laser printing in Wikipedia
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
Laser printer supplies
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.
