Creating a Protective Environment for Computers, Printers and LCD Screens

There is much more to protecting computers, printer, TV and touch screens in hazardous and harmful environments than just enclosing the device in a metal box. Industrial areas, outside locations and unmanned locales provide different hazards and potential problems for any electrical equipment.

In industrial areas the amount of airborne particles and liquids can be extremely high. Not only are industrial locations extremely dusty in many manufacturing and processing facilities, water and liquids are used constantly to clean and wash down surfaces.

So whether it’s a computer, a printer, an LCD screen or a touchscreen and it is to be used in an industrial area it has o be protected from a wide variety of hazards. Whatever device is used, the enclosure that protects it must be dustproof to stop airborne particles getting inside the electronics and causing havoc.

Furthermore, if water is used, even in small quantities the computer enclosure (or printer/ LCD enclosure) needs to be waterproof too. Indeed, some industries, particularly food processing, water is used very liberally so any computer enclosure of LCD enclosure needs to be completely water tight.

When it comes to outdoor use, there are other considerations to be taken into account. Of course, waterproofing is vital for any device that is to be kept in the open air, but also the device needs to be protected from the unwanted attention of vandals or thieves, especially in unmanned areas. For this purpose they need to be solidly built and be strong enough to withstand a heavy impact.

The Story of Ink, Its Many Components, and Its Use Today in Computer Printers

Mention the work "ink" in a conversation at the office today and most people immediately think of computer printers and fax machines. Ink is a popular term considering how many pictures and documents are printed around the world every day using a computer printer, both at home and in a business environment. It almost seems we're always running low on ink. Printing of this nature has become a daily occurrence since personal computers have become part of our daily lives. There is obviously no sign of computer printers going away any time soon. Aside from printer ink though, there are other interesting types of ink in existence today, with some forms of ink dating back centuries.

Ink is defined as a liquid or semi-viscous substance pigmented to various colors and used for writing, drawing, marking, and printing. Composition and consistency of inks are varied according to their specific use. Every ink however, must have two basic components,  the pigment, or coloring, and the vehicle, the liquid with which allows the ink to be dispersed. Some of the most commonly used inks are writing ink, printing ink, drawing ink, and even invisible ink. Ink  happens to be remarkably similar to paint with its only difference being its actual use.

Some of the earliest inks were composed of a substance called lampblack which is a form of soot or carbon material typically black in color. This was mixed with a glue or gum along with water to form a sort of ink-paste. These inks were labeled as india inks and could be a form of the first permanent ink because the carbon like material is inert and cannot be bleached or faded by direct sunlight. There are many color variants for these india inks but they use artificial dyes instead of the lampblack or carbon substances.

The most permanent of permanent inks however is a version called iron gall ink. It is made using iron salts and gallic acid, a complex phenolic substance called tannin, and of course, some water. This type of ink actually does not show up well when applied to paper until it dries. At this time, the ink actually oxidizes and changes state with the black color as a result. This type of ink may even include some blue dye if it is used for writing or printing because is it difficult to see until it has oxidized. This type of ink could be found in some early fountain pens. Colors were introduced to the ink-making process in the early eighteenth century and the process of manufacturing ink has only gotten more elaborate since then.

The twentieth century brought about many more complexities regarding ink production. A wide variety of synthetically produced colored dyes and a laundry-list of chemicals are used today in ink manufacturing. Ink is flexible, it can be used in countless fashions and in a wide assortment of printers and printing presses. There are permanent inks and there are even inks which are erasable using a standard pencil eraser. Aside from the common ink pen, there are inks sold in jars and inks sold in plastic printer cartriges. Where will we see ink next? It's obvious, the technology involved in ink manufacturing as well as the way we market it will continue to evolve based on the needs of the human race.

Acquaint yourself With Computer Printers

A computer printer is a device used for printing text or images on hard copy stored in electronic form, generally on physical print media like paper. Printers are designed to support both local and network connected users simultaneously.

Nowadays, modern printers can directly interface to electronic devices like digital cameras. Some printers that come with non printing features are commonly known as Multi-Functional Printers (MFP) or Multi-Function Devices (MFD). It integrates various functions of multiple devices into one. Such types of printers are extremely useful for small businesses and home offices.

As opposed to a traditional printer, a multi-functional printer is a combination of devices like Printer, Scanner, Photocopier, and Fax Machine. Likewise, there are numerous other types of printers widely available in the market. Let’s take a look at them:

Laser Printer: A laser printer works in a similar fashion as a photocopier does. It has a roller which is charged with electricity. A laser beam is passed to remove the charge from portions of the roller. The parts hit by the laser are powdered by the toner which is then transferred from the roller to the paper. Finally, the ink is baked into the paper with the help of a heater incorporated in the printer. People generally prefer laser printer because of its ability to give high quality output and high speed.

Dot Matrix: It has a print head that moves across the page. A dot matrix printer produces characters using a cluster of pins which press an inked ribbon to the paper, thereby creating a dot. Each character is made in the same way. Dot Matrix printers are relatively cheaper and durable. These qualities still attract businesses which use them as invoice printers.

Ink Jet and Bubble Jet: It works in a manner similar to a Dot Matrix Printer. However, its print head sprays liquid ink onto the page instead of pressing a dry ink against the page. Ink jet and bubble jet printers are better known as predecessors of laser printers. They produce better image quality and run faster.

From inkjets to monochrome and color lasers, different printers are designed to accomplish different tasks. Companies like DELL, CANON, LEXMARK, BROTHER, EPSON, and HP HEWLETT PACKARD are most preferred when it comes to buying a printer. Nowadays, computer printer support is widely available on the Internet which saves you from taking it to any expensive technician for troubleshooting.

The Truth About Computer Printers And Printer Ink Cartridges

Today's printers are heads and shoulders above their predecessors. Inkjet printers can produce excellent photographic quality prints, while laser printers can spit out paper at a rate of 85 pages per minute or more. In fact, there are many different kinds of computer printers available in the market that sometimes it's hard to keep track of them all. Here's a list of the major categories:

Color Inkjet Printers: While slower than laser printers, color inkjet printers are also a fraction of the price of a color laser printer. Inkjets can produce quality color documents and photos, as well as black and white prints.

Color LaserJet Printers: While more expensive than color inkjet printers, laserjet printers are still a bargain, and often come with several paper trays to give you maximum printing flexibility.

Multifunction Printers: The latest trend is multifunction printers, which allow you to scan, copy, fax, and print with a single piece of equipment. This saves space, money, and time. This machine is very convenient and really saves you a lot of money because it is an all-in one machine.

Photo Printers: Specialty photo printers give shutterbugs another great reason to snap pictures. These peripherals often allow you to print directly from your computer, digital camera, or mobile device. Photo printers are great for professional photographers as well as hobbyist. It also comes in a very handy form and portable packaging.

Black and White Laser Printers: If you don't work with color, black and white lasers have never been more affordable. The emphasis is on speed, high print resolution, and multiple paper trays.

Mobile Printers: Mobile printers are gaining popularity among students and business people on the go. While they're slower than other types of printers, mobile printers have the advantage of printing from numerous sources and often have wireless connectivity capabilities. This machine comes in a handy form and can be easily transported.

If you haven't browsed the printer aisle of your local office supply store recently, you'll be shocked to learn that you can buy good quality, brand name printers. Sound too good to be true? Well, in a sense, it is too good to be true. While the price of the printer is lower than the cost of manufacturing it, printer ink cartridges can cost as much or more than the purchase price. In other words, the manufacturers don't make money on the printers; they make money from the ink. It's as though every time you buy printer inkjet cartridges or toner cartridges, you're purchasing your printer all over again.

How do printer manufacturers get away with it? Most often by using scare tactics. They convince consumers that the only reliable printer cartridges are those made by the printer manufacturer. In fact, nothing could be further from the truth.

If you don't want to buy expensive original equipment manufacturer (OEM) ink cartridges, what are your options? There are two choices: Compatible print cartridges and remanufactured ink cartridges. Compatible cartridges are made from brand new parts and meet or exceed OEM standards, but are a fraction of the price. Buying compatible cartridges is similar to buying a store brand of peaches, rather than a name brand.

Remanufactured cartridges are recycled cartridges that are taken apart, inspected, reassembled, and filled with high quality ink. These are even less expensive than compatible print cartridges.

It the world of printing, you can have your cake and eat it too, simply by taking advantage of low printer prices and pairing them with inexpensive compatible or remanufactured ink cartridges.

Evolution of Computer Printers

The evolution of computer printers has been truly remarkable. In fact, their rapid growth has transformed the entire printer market on its head. Today, unbelievable activities can be carried out in your printers. Whether you require DVD printing or CD printing, they all can be done easily using different technologies that are available today.

Computer printers have evolved in more than one ways to what it is now. They were first introduced in the market in the eighties for normal printing purposes. Though they have been made governmental and professional in their use for quite some time now, there were few printers that were known to exist in fifties that were really fast in their operation. The ones that were used on Univac computer is a classic example for this case.

When the printers were first introduced in the market, their speed was calculated in terms of characters printed per second. However, the modern day printer's speed is calculated in terms of number of pages that get printed per every minute. This can in turn make the huge difference.

Finding different types of computer printers is really an easy task. Irrespective of what your printing requirement is, you are sure to get one machine that will fulfill all your requirements. For example, you can easily find toner-printers that operate using the principle of xerography. And the commonest type of toner-printer in the market is a laser printer.

Inkjet printers represent another form of modern printers. These printers operate by spraying precise and small amount of ink materials on to the paper. Printers that make use of solid ink and dye sublimations represent another category of printers. It is also not hard to find printers that do not make use of ink for its purposes. The latter type of printers, in fact, makes use of dry crystals that are colorless.

With all these types of printers around us and with the technology that they possess, it is so easy for any one of us to forget the actual printing process that is involved in them. We cannot be blamed even if we forget the fact that the art of printing was existent thousands of years back.

In Europe, printing made its foray way back in 14th century. Back then printing was done on textiles and it had certain religious significance. It took another hundred years or so to see printing evolving itself. By now, printing was made on different materials. No later, playing cards too were printed this way. Gutenberg is largely credited for evolution of printing technology in Europe in fifteenth century. In fact, the printing press that was invented in Germany by Gutenberg changed the way books were being reproduced. In more than one ways it helped spreading knowledge, not just in Europe but elsewhere as well. Books no longer had to be copied by hands one after another as there was a serious alternative in the form of printers! Soon after this printing revolution, master printers were being produced that could print different materials in large quantities. The printers that modern day computers use have evolved from these printers. It's hard to believe, but it's true.

Computer Printers: Dot Matrix Generation to All-in-One

I remember those dot matrix computer printers which were screeching and screeching as they slowly printed out your documents. They used to make lot of noise, annoying but they were high technology of that time. Since then computer printers have come a very long way. Nowadys, not only you got high speed printers but also you have fax, copy, scanner included which means all office instruments aggregated in one compact device. The good point about this multifunction peripheral is that it doesn't cost too much.

Do I need to go for specific brand?

There are tons of brands out there that is hard to choose. Brands like Dell, HP, Cannon, Epson, Brother, Konica Minolta, Lexmark, Samsung, Toshiba, Sharp. Each one of these brands has its own specialty and quality. However doing some research is vital to find your appropriate computer printer. You don't want to purchase a printer which is not worth buying. You should first recognize your needs. Are you willing to print out a large volume of documents per day? Then definitely laser printer would be your choice.

Maybe you don't need printing tons of papers but you want to print high quality color photos, then you certainly should go for photo computer printer. If you need printing large volume of photos per day then inkjet printers will cost you lot of money changing cartridges every week or so. But if don't care about cost of changing cartridges regularly, then inkjet computer printer delivers high quality print outs. Maybe you just need scan and fax functionalities then you don't have to go for expensive printers like laser ones. The small desktop home printer would perfectly work for you. Maybe you are a owner of large printing, finishing factory, then you will need a production printing MFP.

All-in-one Computer Printers

Nowadays, as I said computer printers do much more than just print documents. Plus printing, faxing, scanning, copying, even e-mailing are additional features which are aggregated in one machine. Most computer printers will copy documents, scan pictures and documents with their built in scanning capabilities. The print feature is even advanced in some models, allowing you to print high quality pictures as well as high quality documents. Different models provide different functionality, you can have all your office needs taken care of with one easy to use computer printer model. That cuts down on the space your units take up, it saves you money, and it's very convenient.

Recently Hewlett-Packard presented a new generation of multifunction or all-in-one mobile printers which only focus on printing functionality but in multiple ways. They are 5lb printer, lightweight, compact and portable. You can print with wire and wirelessly through Bluetooth from your cell phone or PDA. You can print high quality photos from your memory card, digital camera in your car or office. Compare to first generation of printers (dot Matrix), there is no noise at all. They equipped with antivibration technology which means no noise, no move while it's printing.
