Inkjet Printers

The ink jet printers are one of the most widely worldwide used printing technologies thanks to its flexibility, performance and low operating cost and end user price.

These characteristics determine that these devices are present in all areas where there is a computer, both at home and in the office and industry. This article looks at the basics of its operation.

Inkjet printers

The printers use inkjet systems are equipped with a print head with tiny holes throwing ink drops, led by a program that determines how many ink drops and when should be released.


The mixture is important for the formation of color, and it is why color ink jet cartridges usually have three colors (cyan, magenta and yellow) besides black, forming all colors from the mixture of these four inks.

The photo-quality printers can work with up to 12 colors (light magenta, cyan, light black, dark blue, orange, red and green among others) to achieve greater fidelity in color gradations. The fidelity of the image depends the technology used and the quality of the ink.


Bubble jet or thermal

In this technology, the printer heats small amounts of ink at a temperature of about 500° C. With warming a bubble is formed and forces ink droplets leaving the nozzles. The process takes about 20 millionths for each drop formed.

That is the system used by manufacturers such as Hewlett-Packard, Lexmark, Xerox and Canon. The mechanism is in the ink cartridge, making the value of the cartridge is more expensive, but less maintenance and use of all content, because it is under pressure. The resolution is good, and has an optimal cost / benefit ratio.

Inkjet printers


System used by Epson, uses a piezoelectric crystal that changes shape with electricity. Thus, the crystal generates sufficient pressure to expel a small drop of ink, very small, reaching very high resolutions, with almost imperceptible gradations of color.

The printing mechanism is in the printer cartridges, being the cartridges just ink reserves, but with an ink flow based on suction. This system accept dye inks or pigmented base. Its resolution is optimal, but has the disadvantage that the heads may become blocked if that is not used regularly.

Ink Types

Base Colorant

They are soluble molecules in a base colored ink forming a true solution, completely homogeneous and stable. They are fairly inexpensive, and are used both as original cartridges recharged, its durability is average and it is not waterproof.

Inkjet printers


Are insoluble colored particles that are dispersed, usually by additives, so that they remain almost stabilized and homogeneous suspension. Epson and other manufacturers to use in their original cartridges.

The definition of colors is greater than the dye ink, and also durability, used papers with good quality becomes higher the 10 years.

Because of its high degree of water resistance, it is also used in transfer papers, widely used for printing t-shirts, shirts and other fabrics.

You’re buying a printer? We help you to choose it

On all operating systems, the printing method is the same, but choose which is the best printer for our home or office depends on multiple criteria. In this article we will give you several tips for you to consider when buying a printer.

Fortunately, there are many options when buying a printer, and the specific purpose of this article is to help you in choosing the right printer for your needs.

When to buy a laser printer and when buying a printer ink jet

The laser printers are best placed in the corporate environment, because they have the best cost / benefit per printed page, and besides that, supporting a large number of prints per minute. The latest models come with Wi-Fi and can be connected directly to a network. Color laser printers are gaining market share quickly, before largely dominated by black and white.

In the other hand, inkjet printer are recommended for residential or office when you need to print only a small amount of pages. It is much cheaper choose a multifunction printer, instead of buying for home or office a printer, scanner and copier by separate.

Over time, inkjet printers have improved print quality with regard to text and graphics, however, the cost of the cartridges is higher than the price of the printer many times, so which many users opt for the so-called “alternative cartridges”, cheaper than the originals.

I have a small office, what is the right printer for me?

In this point, the most suitable is a multifunction printer. Through this device, you have three devices in one: printer, scanner and a copier machine. In addition we will save a lot of electricity and floor space. You can set it to print in black and white, allowing us to extend the life of the color cartridges.

An “alternative cartridge” harms the printer?

Everyone says the price of original ink cartridges are the great villain of the printers. But that does not mean that generic and cheaper cartridges, with more amount of ink, are the best alternative. While they may not damage the printer, the fact is that sometimes the performance is much lower and the final page cost is close to the original cartridge manufacturers.

How to understand the print speed?

Print speed is measured in ppm (pages per minute). When we see that a printer is capable of printing 36 ppm in black and 19 ppm color, we know if a printer is fast or not. The faster printers are those that use two cartridges at the same time, so achieve good ppm rates. It is also important to know the time it takes to print the first page, that is, the time it takes the printer to begin printing the first copy.

How to understand the resolution of a printer?

The resolution of a printer is measured in “Dpi” (dots per inch), i.e. dots per inch. The higher the dpi, the better the image quality. If a printer which claims 6000×1200 dpi resolution means you can print 6000 points horizontally, and 1200 vertically in a square inch.

Which it is a duty cycle of a printer?

It called “duty cycle” to the amount of monthly impressions you can deliver the equipment. This information is of vital importance, since through this data can know if you want the printer is large-sized or not. The higher the cycle of the printer, more impressions per day.

What is the most appropriate printer for printing photos?

The Inkjet printers have an important advantage in this type of printing. Even in the cheapest models, we can print high quality photos. To achieve high quality is also necessary to take high-resolution photos

In this point, if we have an image of poor quality and low resolution, it is likely to look good on the screen of your computer or mobile device, but when printing on paper, never get a good quality. The higher the dpi, the better the print quality.

What are the connectivity options offered by printers?

The most common method today to connect the printer to the computer is through USB, since parallel ports has long ago stopped using, at least in the home environment and small office.

Other ways to connect a printer to the PC is via Ethernet or Wi-Fi, a method that is becoming very popular these days.

Who likes to photograph, look for a printer with input cards CF, MS, SD, xD, a resource is PictBridge, this port allows the printer to receive photos directly from a camera that also have that kind of connection.

How to know if the capacity of the paper tray will be adequate for my needs?

Everything depends on the daily volume and the type of printing you need. If you want to print envelopes or paper with high grammage, the tray will be compromised.

How buy a printer

Therefore, it is always important to check what is the capacity of the printer trays, both the tray to store the paper to be printed, such as tray receiving the printed paper. Printers with low capacity need to be provisioned more continuously.

I have problems installing drivers in Linux

The inability to install the drivers of some printer models in Linux distributions has been a headache for many people. Currently manufacturers provide drivers for almost all operating systems.

Not to take any chances, when you have chosen the printer, access the website with your favorite Internet browser and make sure the printer compatibility with Linux distributions, read comments from users and end up taking your decision.

How to calculate the cost per page of each model?

For this operation, it must divide the price of the cartridge by the number of pages it prints (information given by the manufacturer). This calculation is very important, since it will give us an idea of the cost of operating the printer, which will help us to calculate the cost when we have to deal with the replacement of the cartridges.

What kind of paper can I use?

The A4 paper is accepted in all printers. If you want to use other formats and weights, see if the printer model that you want support others sizes. Any unsupported paper can damage the printer.

You know InkSaver?

Before you buy your printer, you can install on your PC a little program called Inksaver. It reduces the consumption of inkjet printers, prolonging the time of use of each cartridge, in addition to full control of how much ink that is used by the printer.

Types of printers

A printer or a printing device is a peripheral that when connected to a computer or computer network by wired or wireless connection, offers the ability to print on paper or another substrate, text or graphics produced by an software application.

With deep roots in the technology of typewriters, with the passage of time printers have undergone significant changes. This is closely related to the development and evolution of graphical user interfaces in operating systems like Windows, Linux and Mac.

After that users began to change the way they used their computers, and the work that they performed with this PCs become more complex, the printer technology had to be modified and adapted to the specific needs of users, up to a degree specialization in which we can find printers optimized for vector drawing, printers specifically focused on high quality images printing, and others devices optimized for text printing. We can even find three-dimensional laser and ink printers. An example of this is the ZPrinter 650 3D printer from Z Corporation.

Types of Printers

Currently, most of the sold printers on the market are the models called multifunction printers, which provide us, plus the ability to print, options to copy, scan and capture images.

Such printers incorporate a technology that you could only dream just a few years ago, when the dot matrix printers were kings, and are able to provide the user with a number of useful features and offer significant flexibility even if the printer is not physically connected to the PC.

Types of printers

Printers are typically classified by characteristics such as chromatic scale which is capable of printing, ie if the device prints in color or black and white, the connection type, the number of pages per minute that are able to process and print, and the specific type of technology that uses for it.

Regarding the type of connection, there are several protocols such as USB, Ethernet, wireless by W-Fi, USB and parallel port, the latter being the most widely used today.

From this point, we will know the different types of printers that can be found in the market and its main characteristics. Also we will know how they work and the type of features they offer, in this way we will have a better picture to make an intelligent purchase that really fits in our needs.

Dot matrix printers

One of the example of dot matrix printers more known is the Epson LX-300, which uses a technology that allows print when a needle, or a character wheel strikes an inked ribbon, which finally prints the image or text onto paper. Virtually nobody uses them today, as they have been largely overcome by the ability and quality of inkjet printers.

Types of Printers

Typical uses: Commerce, small office.

Ink-jet printer

The Ink-jet printer is one of the printing technologies most commonly used and widespread because they are cheaper to maintain and easy to operate. These printers print using one or several different ink cartridges, which are usually Cyan, Magenta, Yellow and Black, the same pigments commonly used in offset printing, and guarantee an excellent quality printouts, reaching sometimes similar quality to the laser color prints.

Types of Printers

Typical uses: Commerce, small office, home, industry, graphic design.

Laser printer

One of the most important features when it comes to laser printers, is undoubtedly the print quality can achieve. Over the years has been widely used for prepress in shops of small size printing. Today we can find in many electronics stores really cheap laser printers, which are able to offer a lot of interesting features.

Types of Printers

Typical uses: Commerce, small office, printing, graphic design and in business where large volumes of high-speed quality printing is required.


The plotter printing technology, also called tracers, is widely used today for all kinds of projects such as advertising billboards, and they are also used to commercial and advertising posters in extra-large sizes.

This is a tool that allows the user compose large prints, as some plotter models are capable of printing projects up to 6 ft. or more wide. Another area in which the plotter is used, is in the field of architecture for drawing planes.

Currently, plotter technology uses the principle of inkjet printing, which offers a high quality and flexibility.
