What is the difference between laser printer and inkjet printer?

Published by March 19,2024

When we buy a printer, whether to buy a laser printer or an inkjet printer.we must understand the difference between the two to make the right choice. First we must know the following:

What is a laser printer?

Laser printers were born out of laser imagesetter technology in the late 1980s and became popular in the mid-1990s. It is a print output device that combines laser scanning technology and electrophotographic technology. Its basic working principle is that the binary data information transmitted by the computer is converted into a video signal by the video controller, and then the video signal is converted into a laser drive signal by the video interface/control system, and then the laser scanning system generates a character information. The laser beam is finally imaged and transferred to the paper by an electrophotographic system. Compared with other printing equipment, laser printers have the advantages of fast printing speed and high image quality; but the use cost is relatively high.

What is an inkjet printer?

Inkjet printers convert colored liquid inks into fine particles through print heads and spray them onto printing paper. Some inkjet printers have three or four print heads to print four colors of yellow, magenta, blue, and black; Four-color printing.The main print head brand for inkjet printers is Epson. There are many models of Epson print heads used in industrial printers. For example, Epson DX6 TX800 F192040, Epson DX7 golden print head, Epson 4720 print head, etc. Of course, the print head brands of industrial printers are not only Epson, but also Konica, Ricoh, Seiko and so on.

Next, let's introduce the difference between laser printers and inkjet printers? They have the following differences:

Differences in Imaging Technology

The principle of the laser printer is to use the laser scanning imaging technology to make the imaging drum charged with static electricity to attract the toner, and at the same time, the heating roller heats the paper to melt the toner in the paper to complete the thermal imaging printing process; the principle of the inkjet printer is The printing process is completed by controlling the dot matrix of the printing print head to eject the printing ink through the digital circuit. Double-sided laser printers can achieve automatic double-sided printing, while inkjet printers require manual methods to achieve double-sided printing.

Differences in printing components

The commonly used consumables of laser printers are mainly toner cartridges, while the consumables of inkjet printers are ink tank and print heads. High-end inkjet printers and plotters have separate ink tank and print heads, while household and ordinary commercial inkjet printers are sub tank and print heads. Two in one. Laser printer cartridges can print thousands of sheets, while inkjet printer sub tank can only print hundreds of sheets.

The difference in printing speed

The printing speed of laser printers is significantly faster than that of inkjet printers. Of course, inkjet printers can also choose fast printing mode, but in this mode, the printing effect of inkjet printers will be reduced.

The difference in printing effect

Usually, because the imaging technology of laser and inkjet printers is different, the printing effect of laser printers is better than that of inkjet printers. Of course, if the dedicated inkjet photo printer uses photo paper to print, the effect is not good.

The price difference

Usually printers are divided into A3 and A4 format printers, and the price of inkjet printers is lower than that of laser printers under the same format. In addition, consumables are the price of toner cartridges are more expensive than ink tanks. Under normal circumstances, the price of an A4 format black laser printer can buy an A3 format color printer.
