Laser printers are devices that create printed documents by directing a laser beam across photoreceptors. The electrostatic charge created by the laser enables the drum to transfer toner to paper. This process produces crisp, clean text. In addition to printing, a laser printer can also copy and scan. Some models can even fax. A laser printer is a reliable, high-quality alternative to an inkjet printer. However, there are a few factors to consider before purchasing a laser printer.

If you are a small business, a color laser printer is an excellent option. You’ll find that you can get a great print quality at a fraction of the cost of a higher-end model. The Canon Pixma TS9120, for instance, costs just 19.8 cents per color page.

When it comes to the type of document you need to print, the laser printer has the advantage of being faster and more durable than an inkjet printer. If you want to use your printer for bulk printing, you’ll have to buy a model that can handle large quantities of pages.

There are several different types of laser printers, but all work in a similar way. The earliest laser printers had huge, photosensitive drums. They used a proprietary page description language that made the supporting software complex. With a modern color laser printer, the dots are much smaller and the raster is less than a mm.

Unlike an inkjet printer, a laser printer relies on toner, a powdered material. Toner is usually stored in a single cartridge, although some models have USB ports. After a few uses, a toner cartridge must be replaced. Each time a toner cartridge is replaced, you must remove the drum assembly and replace it with a new cartridge. While replacing the toner, it is important to make sure you don’t touch the imaging drum, which can cause print problems.

Color laser printers produce prints using a combination of cyan, magenta, yellow, and black ink. Most printers will have a single laser scanner assembly for each color. These are usually located in the front of the machine. Before printing, all four CMYK toner layers are preprocessed.

Color printing adds a lot of complexity to the printer’s printing process. To ensure that the pages you’re printing look as great as possible, you should purchase a model with a high monthly duty cycle. Higher monthly duty cycles are better suited to high-volume jobs.

For black and white, you’ll want to look for a printer with at least one megabyte of memory. For full-color letter-size pages, you’ll need at least 4 megabytes. Depending on the resolution, you’ll need at least 16 megabytes for color.

If you need to print a lot of documents, you’ll want to get a printer with a large toner capacity. Brother and Canon printers have models that come with extra-large ink capacities. HP has a series of printers that can save you money. Another feature that you may want to consider is the ability to use Google Cloud Print. Using a Google app, you can print from your computer or mobile device to your printer.
