The laser printer was invented in 1969 by Gary Starkweather, a researcher who modified an existing xerographic copier to create a fully functioning prototype by 1972. Early printers easily filled entire rooms. Since then, the technology has improved in practically every way.

Today you can buy a reasonable machine that will print pretty much anything. Desktop printers seem also to get smaller and lighter with each passing year, and there are even mobile models available. The element that remains fundamentally unchanged, however – albeit with a whole lot of streamlining, innovation and material upgrading – is the seven-step print process outlined below.

Raster Image Processing: An RIP (Raster Image Processor) is built into most laser printers. This is the part that ‘programs in’ the image that is to be printed. It encodes the image into a page description language – thus allowing your printer to ‘understand’ the image as a coded sequence. Each page is made up of horizontal lines, and each line is made up of dots – these strips of dots are known as scan- or raster lines. This information is stored in your RIP as a bitmap. Color documents require four bitmaps – one in each of the color toner layers, i. E., cyan, magenta, yellow, black.

Step Two – Charging: A negative electrostatic charge is projected across the surface of a photoreceptor. The photoreceptor is a revolving drum or belt that holds this charge while in darkness. In other words, once charged, the drum is like a roll of film waiting to be exposed to light – in this case, a laser beam.

Step Three – Exposing: The laser is aimed at a system of mirrors and lenses that bounces it precisely onto the revolving drum. The rasterized data in memory switches the beam on and off to form the dots of each scan line. The beam affects the negative charge that has been applied to the drum, neutralizing or reversing the polarity of the charge wherever it touches, i. E., it ‘cuts out’ the ‘to-be-printed’ parts. In this way, the bitmap is applied to the drum as a static electric negative image. Lasers are used because of the uniformly narrow beam they generate. Many printers that are incorrectly termed ‘laser’ expose using page-width spanning LEDs rather than a laser.

Developing: This latent image is exposed to toner. Toner comprises of tiny particles of dry wax or plastic powder with carbon black or other coloring agent mixed in. These negatively-charged particles are attracted to the positively-charged/neutral parts of the latent image (opposites attract) and are repelled from the negatively-charged areas (like repels like).

Transferring: The drum or belt is pressed or rolled onto a page, which transfers the toner to the surface of the paper.

Step Six – Fusing: The paper goes through the fuser assembly, which bonds the toner to the paper using heat and pressure.

Cleaning (Step 7): A soft, plastic, electrically neutral blade cleans excess toner from the belt/drum and puts it in the waste reservoir. Any residual charge is removed by a discharge lamp.

It is a marvel of modern technology that these steps happen in such rapid succession. The entire process can happen before the drum completes a single revolution. So the next time you look at your laser printer, take a second to appreciate the beautiful complexity that enables you to print out your documents.

It is hardly possible to imagine any work environment without a printer. There are a wide variety of different types of printers available, but the laser printer has become the favourite of those that require good quality printing that that is produced reliably and with the minimum of fuss. They can print on a variety of paper types. These machines work with a laser beam that produces an image of the original.

The lifespan of this equipment is most often expressed in the number of pages printed, rather than in time units. This equipment requires a measure of maintenance. Toner cartridges need to be replaced on a regular basis. The roller and feeding mechanisms also requires regular cleaning with a lint free cloth. Over heating should be avoided, since it can cause damage to the plastic gears and rubber rollers.

The working of this equipment is relatively simple. The principle of static electricity is utilized to positively charge a drum. Next, a laser is used to create a negative electrostatic image on the drum. After the drum is coated with toner, it is rolled over a negatively charged sheet of paper that attracts the toner, and in this way the image appears on the paper.

These printers are quiet and fast. The toner that is used normally last much longer than ink. The excellent quality of the printed material allows for sophisticated applications, such as the printing of technical drawings and other intricate documents. Quality of printing does not gradually decrease, as it does in other types of printers. Their ability to function efficiently in a networking environment contributes to efficiency and cost effectiveness.

Many people see the high initial cost as the main disadvantage of this product. Replacement parts and maintenance is also costly. They also do not perform very well in hot and humid climates, and some studies have hinted at potential health problems. Their all in one features can cause chaos in case of a breakdown, and they take up space.

There are some potential hazard that can be avoided when exercising care and caution when operating or maintaining this machinery. Never use an ordinary vacuum cleaner to remove toner spills or build up. They may ignite and cause a fire, or even a small explosion in the vacuum cleaner bag. It is also important to avoid the inhalation of toner articles, as this may lead to respiratory problems.

Selecting a new printer depends upon your specific needs. Aspects that need to be considered include the need for sharing the equipment in a network environment, in which case the speed of this type of printer may be the deciding factor. The need for quality originals is another important factor. If you require a high volume of printing, there are hardly any other choices.

Printed matter is still very much a part of life. Various laws require hardcopy backups of certain types of document, and many potential clients prefer printed matter above electronic information. Printed versions of documentation are also invaluable for review and evaluation purposes. For best quality and reliability, nothing beats a laser printer.
