Computer Printers - Important Tips To Enjoy Them

Printers are becoming more advanced and can print clearer images, are combined with fax capabilities and can print large quantities at a time. Printers that cannot offer a wide degree of access are usually thrown away in favor of those that do. The ink used in printers has also changed through the years and can use toner, ink, other liquids, or even no ink at all. Printers are designed for low-volume, short-turnaround print jobs; requiring virtually no setup time to achieve a hard copy of a given document.

Printers are categorized according to whether or not the image produced is formed by physical contact of the print mechanism with the paper. Impact printers have contact; nonimpact printers do not. Printers are cheap, but ink cartridges cost an arm and a leg. The higher the print quality, the longer it takes to print a document, and the more ink you use in the process.

Printers have certainly come a long way since the inception of the character and and dot matrix printers. These ancient products (ancient in technical terms being as few as 10-15 years) were what are known as impact printers, simply because they needed to make a physical connection with the paper in order to achieve the ink-on-paper result.

Dot matrix printers came equipped with a group of pins that touched a ribbon which then connected with paper to produce the finished product. Character printers, which worked on the same principle as electric typewriters, used a bar or ball whose surface was embossed with all the characters you now see on any keyboard. These characters made contact with the ribbon, which in turn made contact with the paper.

Today we use non-impact printers - those that do not make physical contact with the paper to create the papered reproduction. The most prevalent for home or small office use is the inkjet printer - an economical choice for all but the most serious graphic arts requirements.

There are five basic parts to an inkjet printer: the print head assembly, the paper feed assembly, circuitry control, power supply, and printer ports.

1. The print head assembly is the heart of the printer workings. It's what brings the ink to paper by means of a row of nozzles.

2. The print head may be part of the inner workings of a printer cartridge, or they may be separate parts. Cartridges are responsible for delivering color and shading. Most inkjet printers made nowadays offer color printing. Some may require as many as three distinct cartridges, but generally at least two - one black, one color. The motor is part of the print head assembly as well. It's the part that enables the ink and cartridges to move across the paper and produce the hard copy. It also keeps the cartridge stable when not in use.

3. The paper feed assembly includes the paper tray, which holds the paper ready for a printing request, and the rollers, which deliver the paper to the ink when a printing job is requested.

4. The power supply is simple - it's what gets the electricity to your printer so that it can do its job. Printer circuitry controls take the message from your keyboard and mouse and deliver it to the printer so that the requested hard copy can be produced.

5. Printer ports, also referred to as interface ports, much like a telephone jack, enable the peripheral (the printer) to talk to the computer. While in older models parallel ports were the norm, the newest printer models connect via USB ports, which require a special USB cord.

Laser Printers vs Inkjet Printers
Laser Printers are commonly used printers that are known for its rapid printing abilities. The other marked feature of a laser printer is the high quality text and graphics printing. When considering the most practical printer in use for today's business office, the laser jet printer seems the most prudent choice. In general, when compared to its rival the ink jet printer, the advantage of the laser jet is not only because of its quality and efficiency, but in the long run, it's the best value printer on the market. Laser printers simply produce a higher quality of color graphic or image, which make it ideal when the print job involves the printing of sales brochures or a mass mail-out to customers. When deciding on whether to purchase an inkjet or a laser printer, volume usage will be a key factor.
