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 printer or inkjet printer – Which one would you go for

“Laser printer or inkjet printer” this is something which must be rolling in your mind if you’re thinking of buying a printer. Buying a printer to a great extent depends on the type of work you would like to do on the printer.
For instance, if you want to print few photos, few e books or print any other project work an inkjet printer would help your cause. Inkjet printers are far less expensive than laser printers. An Inkjet printer uses a unique printer mechanism, which provides quality printing. They transfer tiny droplets of ink directly to the page. This is the reason why you will find most photo printers are inkjets. If you want to print photos at home, photo inkjet printer would probably be a perfect choice.
You might get an inkjet printer for less but they cost high to run. The ink required by inkjet printers is expensive as they are measured on per page basis. On the other hand laser printers have a high initial price but a low running cost.
When to opt for laser printers?
No matter laser printers are far more expensive than inkjet printers but they have a low running cost. For instance, if you want to print thousands of photo printouts, e books or print any other projects in bulk, laser printer would help your cause. The quality of printing provided by a laser printer is of a higher resolution as compared to an inkjet printer. You can also use laser printer at home if you require to take thousands of printouts. It would always be advisable to treat a laser printer as an investment rather than an expense.

Hp Laser Printers Versus Hp Inkjet Printers
Posted by admin in Inkjet Printer on July 20th, 2010
These two different types of printers achieve the same thing. They both print, but they go about it in a very different manner. There are major differences in the engines that drive them and the work they are required to do.
Laser printers are designed to be used in a heavy work load environment. The cost per print is much less expensive compared to Inkjet models. Laser printers use a dry mono-component toner cartridge and a laser that shoots the image onto a drum inside the toner cartridge.
Inkjet printers are designed for a different work load. They are designed more for a work station such as an individual’s desk or for low volume type work. The toner or ink is quite expensive. Most are slow, so using them in a high volume application would drive a person crazy waiting for a hundred page report. Let me say something about the cost of Inkjet cartridges. I read an article that said that Inkjet cartridges are more expensive per weight than imported Russian Caviar. Inkjets use a liquid ink that is sprayed onto the paper. They all have a scanner rail that goes back and forth, carrying the Ink cartridges distributing the ink.
I read a post that several people commented on. They said that Hewlett Packard has really gone down hill lately with the quality of their printers. They were commenting on the HP LaserJet 4, a very popular laser printer of the past. It is about ten to years old, but it is a very dependable printer. I still use one in my office!
They were comparing it to several new HP Inkjet Printers. These are completely different machines for completely different applications. If you want to compare this machine to another HP product use the HP laser jet 4250. You really can’t compare these either. The memory, speed and options are made for the latest printing applications. Remember that the HP LJ- 4 was built around 386 computers. By the way, my HP LJ-4 works great with XP.
The price of Inkjet printers is driven by consumers that want something cheap. You get what you pay for. It is the market that creates cheap Inkjet printers. They do work well, but if they break they are not designed to repair. They are known as disposable printers. Not all Inkjet printers are disposable printers. The Inkjet is really progressing and will continue to fill more of the market place. Speed has been an issue but now they have designed some that keep up with the speed of laser printers. HP color Inkjets also make terrific color prints. Even a person with a limited budget can make great presentations, photos and flyers.
When you purchase a printer, you should always consider the type of application that it will be used for. Don’t buy an Inkjet when you’re going to be printing hundreds of reports. Don’t buy a laser printer if you print two or three jobs a day. If you look at cost per print and monthly volume you can’t go wrong. Hewlett Packard printers are some of the best you can buy, but you need to use them in the proper application.
