This is because even replacements are produced according to generally accepted standards.In contrast, cheap printer toners can be released for sale by companies that can reduce the cost of their production or be covered by some kind of promotions or rebates.
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.
Currently, only printers without scanners and additional accessories are less and less sold.However, this kind of printing devices are most often bought by private individuals who want to print only basic documents, applications or home-made essays written in secondary schools. However, printers can also successfully perform much more complex functions and tasks.
It can be seen that it is worth having a small printer at home and using photocopying services. .
