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.
For each order, the production costs are optimized, and the appropriate technique and type of printing is selected. Graphic designers, DTP operators and printers deal with this.They are responsible for the quality of the printout and as soon as something is wrong they are the first to be targeted by the dissatisfied boss. Their work is quite hard and I have to admit that you have to really have a fuss to do it. Work after hours, maximum focus and responsibility - definitely not work for everyone.
They have the appropriate knowledge and tools that allow them not only to replace the toners, but also to repair the entire printing device, if such an order will receive from the incoming customer.
Thanks to this, they can fully develop their business. .
