Color Laser printer or just laser printers use a technology known as Xerography to produce either the black and white copies that we are accustomed to or reproductions of extremely high quality.
Let us first look at the differences in the middle of laser printers and inkjet printers.
Best Laser Printer
In a nutshell shell, inkjet printers spray droplets of ink onto the media currently inserted into the printer or passing the print head (or visa versa), whereas laser printers replacement the ink or powder directly onto a drum which in turn, rotates, and places the impression directly onto the paper being fed into the machine.
The electrically expensed drum, which is coated with selenium rotates, onto which, a laser beam projects the image to be printed, this laser beam using the process of Photoconductivity removes the payment from the areas exposed to its light, the expensed areas which are left behind pick up (electrostatically) the dry ink or toner, and jaunt to print it directly onto the face of the paper being fed straight through the roller.
This technology brings with it some requisite advantages over its competition, the Color Laser Printer's speed can vary depending on several factors such as the intensity of the graphics being processed, some of the best laser printer's or multifunction laser printers as they are called can perform speeds of up to 200 hundred monochrome pages per limited that's an fabulous 1200 pagers per hour, the very fastest and top quality, the best color laser printers that can be purchased may produce a thinkable, 100 color pages per minute, that's fabulous when you think that the technology (Xerography or electrophotography) was invented in 1938 by Chester Carlson.
If you wish to buy a laser printer and use it for color laser printing some of the cost factors which you may need to consider:
The costs of the paper and toner plus the cost linked with the replacement of the drum plus the other consumables that may be required e.g. The fuser and replacement assembly these incommunicable costs will not become apparent until replacement time.
Consider the volume of printing you may require, a multifunction color laser printer with all of its functionality may or may not be what is required by your office, a uncomplicated bubble jet may be ample for your needs.
Anti counterfeiting Steganographic ("secret") marks.
Color laser printing has come of age, with the threat of counterfeiting becoming a real issue as the quality of printing has improved, unscrupulous groups of citizen have found other uses for the laser photo printer, or the readily available laser printer copier that can be found in most corporate environments.
Most contemporary printers mark the printouts they produce with a series of approximately imperceptible dots, these include information such as date, time, serial whole of the printer, all in binary coded decimal dots, this technology is said to have been then follow of the U.S. Governments concern over counterfeiting, and a deal was struck in the middle of the printer commerce and the government of the time to combat this threat, these measures enable a constructor to follow a singular piece of paper back to its source, maybe even to recognize the former purchaser of the motor or consumables, some digital ownership advocacy groups have become alarmed at this level of intrusion into the ownership and freedoms of those that print and write, one such group is the Electronic Frontier Foundation
