Leaser Printer Buying Guide Bangladesh

Leaser Printer Buying Guide Bangladesh

The full form of leaser is Light Amplification by Stimulated Emission of Radiation. A laser printer is a non-impact printer. Laser printers are poor conductors of electricity in the absence of light and good conductors of electricity in the presence of light. Laser printing basically involves photoconductivity. Selenium is a photoconductor. A cylinder or drum core in a laser printer is coated with a layer of selenium. Selenium is charged at various stages of printing and then partially discharged by a laser beam as required.

Laser printers usually print the entire page once instead of printing one character at a time like dot matrix printers. Laser printer characters are printed in non-impact dot matrix format. In this case, the dots are closely spaced. As a result, they cannot be distinguished in general. A laser printer is shown in the figure. The resolution and speed of this printer are higher than other printers. Printer resolution is measured in DPI and speed in PPM. A current laser printer has a resolution of 1200 DPI and a speed of 24 PPM. Laser printers are used in all cases where high power and high-quality printing is required. But laser printer cartridges cost more than other printers.

 

It is better to know the details about the model to be bought from the website of the company before buying. You can know in advance what kind of facilities the printer has, how many pages are printed per minute, how much can be printed with a toner or ink, etc. At the time of purchase check the warranty period of the printer and whether the device packet has been opened or not. While buying the printer, you need to understand the warranty card, and necessary parts like CD, power cord, USB cable, cartridge, or toner. Apart from this, it can be confirmed whether the toner/cartridge for that printer will be available at a later date. Because there are some brands in the market whose cartridges or toners are not easily available.
