Laser Printer- Remarkable Technology With Various Features
Posted by admin in Laser Printer on August 3rd, 2010
These printers employ a xerographic printing process which differs from the analog photocopiers in which the images are produced by the direct scanning of a laser beam across the printer’s photoreceptor. Unlike impact printers, laser printers can print over 200 monochrome pages per minute and the fastest colour laser printers can print over 100 pages per minute. These fast printers are mainly used for mass mailings of personalized documents such as credit cards and utility bills.
The cost of this remarkable technology depends on various factors such as cost of paper, toner and sporadic drum replacement, only the printers with soft plastic drums can be a little expensive. An easy way to reduce the paper costs and filing volumes is to have a Duplex Printer; a printer that prints on both sides of the paper.
Unlike the typical black and white laser printers, colour laser printers add colour tone to the matter being printed. To sanction high registration accuracy some colour laser printers use a large belt to generate the image. All the four layers of the toner CMYK, i.e.: cyan, magenta, yellow and key (black), are precisely applied to the belt, and the combined layers are then applied to the paper in a single step.
The laser printing process mainly includes 7 steps to process an image, once the image generation is complete the printing process starts which permits the use of a very small and compact unit, where the photoreceptor is charged and the entire process can be completed before the drum completes one revolution .This colored laser technology is also helpful for the government, in case of tracking down some important documents. This is done by flashing an LED flashlight beam on the printer which will create a few small, scattered yellow dots which could be used to trace the documents back to you.
Therefore, after the standard laser printers, colored laser printers have definitely created a colour revolution. This leading edge technology is easy to use which enables the customers to concentrate on outstanding results.
Laser Printers or Inkjet Printers? A Buyers Guide
Posted by admin in Laser Printer on July 15th, 2010
Should you buy an inkjet or a laser printer? Often people buying a new printer are confused about whether to buy a laser printer or inkjet printer. The short answer is it depends on what you’ll be using it for, and how much you’ll be using it.
Inkjet printers have a lower initial purchase cost but cost more to run because the ink is more expensive when measured on a per page basis. Laser printers cost more but their running costs are lower and they have a better print quality because in general they have a higher resolution (expressed in dots per inch – dpi).
If you want to print photos at home however, you are best to choose a photo quality inkjet printer.
Inkjets are great for home use and for photo printing. Lasers are good for high-volume applications, like offices, or for applications that need high print quality.
Inkjet printers transfer tiny droplets of ink directly to the page. A laser printer creates an electrostatic pattern on a drum that attracts ink powder that is subsequently fused onto the paper. This is more complex technology so means a higher price than for an inkjet printer.
If you examine the same page printed on both a laser printer and an inkjet, you will be able to see that the characters on the laser printer produced page are sharper. That said however, inkjet printers are getting better all the time in terms of the sharpness of printed characters.
Another aspect to consider is how heavily you will be using a printer. Printer manufacturers express the durability of a printer in terms of duty cycle in pages per month.
For example, a typical laser printer will be capable of a duty cycle up to 7,000 pages a month while a typical entry level inkjet printer is capable of up to 500 pages per month.
Some of the more recent inkjets provide excellent color clarity and brightness, and are very well suited for printing photographs.
While inkjet printers themselves are cheaper, their ink is more expensive per page printed. Ink cartridges need to be replaced fairly often if you print a lot, especially if you’re printing pictures or photos.
The manufacturer’s stated pages per cartridge measurements are very much dependent on what you printing. They are based on only a small percentage of the page actually being covered in ink.
Toner cartridges for laser printers have a higher unit price than inkjet cartridges, but have a higher capacity so that the cost per page is lower for lasers.
The Difference Of A Laser Printer
Posted by admin in Laser Printer on June 26th, 2010
The choice between the purchases of many different types of printers can be a challenging one. As sophisticated technology continues to change the landscape of the office environment, it becomes more and more difficult to determine the best course of action when choosing an appropriate printer. The laser printer, one of the more popular types of printers, has a variety of benefits that sets it apart from its counterparts.
As its name suggests, a laser printer employs the work of a laser beam to complete the printing process; the laser – like a camera of sorts – captures the image to be printed. The information is then printed by the toner cartridge which is standard to the laser printer. While other printers utilize liquid ink in their toner cartridges, a laser printer works with a powder ink that makes for a pristine and sophisticated result. The laser printer, free from ink and, therefore, free from smearing, produces a high resolution, and much more professional looking product than many other printers.
Office environments often turn to the laser printer for exactly this reason and are confident they can trust the laser printer to give them consistent professional results. And when, as is often the case in offices, multitudes of documents are printed at one time, the laser printer more than holds up to this increased need, leaving you free to concentrate on other things.
For a more creative work environment that relies on the printing of graphics and color photos, the laser printer continues to maintain its popularity. As office needs change, the laser printer keeps pace, elevating its technology almost yearly to match the demand for high resolution, photo quality copies.
Because of its price, the laser printer is often relegated to the office, rather than chosen for home use. But either way you use a laser printer, you will undoubtedly find its quality and reliability to be unmatched.
