Print, Print and Copy: Learn more.

Printing, printing and copying are technologies that we often come into contact with in our daily life. In this paper, the principles and characteristics of these technologies will be discussed in depth to help readers better understand their mysteries.

Traditional printing

In traditional printing, we first carve a template, then brush it with ink and cover it with white paper. With a gentle pressure, beautiful patterns will jump out of the paper.

Modern printing technology

Modern printing technology is more advanced. Ink-jet printing, controlled by computer, decomposes the graphics into countless small color points, accurately ejects different colors, and creates colorful visual effects. Laser printing uses the charge characteristics of the toner cartridge to adsorb the toner to the corresponding electrode, and then presents the pattern on the white paper by imprinting.

Principle of copier

The principle of the copier is similar to laser printing, except that the scanning and printing functions are integrated. By scanning the graphic information of the manuscript, it is fed back to the electrode of the toner cartridge, and then the printing process is completed.

Retention time

The storage time is related to the quality of paper, ink or toner and the performance of the machine. No matter what kind of machine, it can print durable data, and of course it can also print short-lived fragile data.
