Printer Pros and Besting Inkjet. Disadvantages of printing on jet printers

Jet printer. This is a type of printing technique using the print technology of the same name. The drawing is applied to the carrier (paper) with liquid dye.

The progenitor of jet printers is a device for recording the received messages from telegraphs, which was invented by William Tomson in 1867. The principle of operation was based on the management of the falling drops of dye on paper by electrostatic laws.

Based on this technology in the middle of the last century, engineers of Siemens developed a device for fixing information on paper. The device had a number of disadvantages, including a high price, poor quality reproduction, paper was getting dirty. But for seismographs, electrocardiographs, multimeters of this quality, it was enough.

Over time, the inkjet seal began to use piezoelectric laws and crystals, which, when passing through them, could change shape and radiate electrons. Further, Canon has developed another method for the output of ink to the carrier. They began to act on a temperature of up to 400 ° C, because of this, the ink from the liquid state went into a vapor-shaped one and went to paper.

The first color apparatus was invented by HP specialists. Three dyes of blue, yellow and purple flowers were used in the press, mixing which could get any shade.

A jet printer device

Printhead

A separate part consisting of many small snot. The device of the print head in different printers is practically no different. Only the number of holes and their location can change. So, in the first models there were only 12 of them, and now it can reach up to several thousand. Ink through the nozzles are squeezed through piezoelectric or thermal technology.

  • The number of colors. Minimum. 4, maximum. 12. The more dyes, the better the seal and better color rendering.
  • Drop size. The less the extruded drop of ink, the more clearly the pattern.
  • Printing resolution. The more points are placed on one inch of the area of ​​the leaf, the better the image.

Best Printer for Home Use and Small Business? Inkjet Vs Laser Vs Thermal Printers

In some printers, the PG is not a separate element, but part of the cartridge

Cartridge

This is a small plastic container of not more than 10 cm long. Black dye is stored in a separate container, and color can be in both individual and combined cartridges. The combined inkwell has the form of a plastic box, which inside is divided by partitions into three compartments.

Paper supply mechanisms

It includes a paper tray, a motor setting in motion of the feed rollers. The tray of different models can be both from above and below. The main problem of the mechanism is to refuse to capture the pages, but this is rare and easily eliminated independently.

Control Panel

Can consist of only several buttons or have a built.in screen to control settings. The panel is intuitively easy to control, can additionally have explanatory inscriptions. Located on the front of the printer.

Frame

This is an outer shell made of black or white plastic. Protects the working mechanism from getting into contaminants, moisture and sunlight. The ALL-In-ONE PRINTER case and a regular printer may vary.

Motors

  • Is responsible for the functioning of the video captivating the page and drawing it into the printer.
  • Drives the car sailor.
  • Activates the mechanism moving the print head.
  • Promotes the delivery of ink from the cartridge to paper.

Connect connectors

LTP cables were replaced by USB and Ethernet. They are easier to use, and they work faster. If the technique is old and has an LTP port, connection to the computer can be carried out through the adapter.

Sensors

  • determine whether the page has got into the apparatus;
  • monitor the location of the head in relation to the sheet;
  • monitor the size and characteristics of the paper;
  • determine the presence of foreign objects inside the printer.

Advantages

The advantages of a jet printer make it a very popular device.

  • The device itself is very cheap, for several thousand you can purchase a decent device that will cope with all everyday tasks.
  • In many models, you can revoke the cartridge yourself, which gives good savings on consumables.
  • On some devices, you can reduce the size of the drop. The seal becomes more pale, but black paint is noticeably saved.
  • You can install a system of continuous ink supply. Then the paint will go from the replenished tanks.
  • Almost any jet printer can print both in black and white and colorful. This makes it possible to beautifully draw up reports, abstracts, etc.D.
  • Devices take up little space, compacts.
  • Often they combine several devices: printer, scanner, copier, less often. fax. These are the so-called All-in-One Printer.
  • Inkjet printers have many more types of compatible papers than the laser option. This gives greater freedom of action. One device can print on ordinary, pussy, photo and other types of paper.
  • The advantages of a jet printer lies not only in an affordable price for the device itself and consumables, but also in the clarity of images. Some models allow you to print full.color high.quality photos.
  • Many models have a low noise level.

The advantages of a jet printer

Inkjet printing is valued for a number of advantages that you should definitely familiarize yourself with. Below are the main ones.

Availability

A huge number of companies are engaged in the production of jet printers, which has positively affected their value. it is quite democratic. Having analyzed over the past few years, we can conclude that they are in the range of 1500-5000 and this included both the most ordinary devices and modern All-in-One Printer.

Simplicity of use

The operation of jet printers is not difficult for novice users. It is enough to unpack the device, connect to the network and start printing out documents with high quality.

Standby mode

Inkjet printers do not need warm.up, they are immediately ready to work and literally after 5-7 seconds you can start printing the first page. Photo

Photos with high resolution, excellent transfer of flowers, clear, bright presenting a jet printer. If in the future it is planned to print them in large quantities, then the acquisition of such a technique will be a successful purchase.

Anyone is suitable

This is another significant advantage of the jet printer. Paper can have a glossy, matte or any other surface, you can make a seal on cardboard. the quality will be at an excellent level everywhere. This is used by people engaged in art, whose activities are related to the seal on surfaces with different textures.

Pros and cons of jet printers

Inkjet printers come in two types: with cartridges, or with a continuous supply system of ink (SNPC). In appearance, jet no different from laser, the main difference is inside. They use two small cartridges that play the role of the print head. With a long simple cartridge without use, it can dry out that it is a big minus.

But cartridges with a continuous supply system of ink open many opportunities in front of their owner. color printing photos without fields, a large tank for paint and a large print resource (some models allow you to print up to 12 thousand sheets using only one bottle of paint). The tanks of such printers can be designed for 4 or more colors, they have special traffic jams and pipettes for the convenience of replenishment, and some models have special valves that can be fixed for safe transportation of the printer.

Among the advantages of jet gadgets stand out:

  • high print quality (including color photographs);
  • low cost of both the device itself and consumables to it;
  • In modern models, the print speed is quite high.
  • a more frequent change in consumables compared to laser counterparts;
  • With a long simple ink in the cartridge, they may dry;
  • Possible spots on paper due to the leak of ink;
  • printed materials are very sensitive to water.

Results: To make the right choice when buying a printer, you need to decide on the tasks for which you purchase it.

For the home, if you plan to print only documents (essays, diplomas, and t. D.), then a laser black and white printer will be a rational choice. Even if you are printing with large interruptions. Most inkjet printers are not like these purposes, since ink is enough from 100 to 150 pages of printed text. In addition, if you use it from time to time, ink can dry in the nozzle of the print head. What will be an additional cost of repair.

If there is a need for color printing, then you need to decide whether the priority will print photos or just images, etc. P. Since colored laser printers in the quality of printing photographs still lose in jet printers. The cost of using a laser color printer when buying new original cartridges is currently high. A set of 4 cartridges sometimes exceeds the cost of the printer itself.

printer, pros, inkjet, disadvantages

So immediately find out how much the gas station will cost or buy new cartridges for your printer.

Inkjet printers are suitable for those who need first high quality printing of photographs, or who often prints, but not in small volumes. From experience, I can say that a jet printer in which 4 separate inkwells for each color will be a profitable purchase. A relatively good margin of ink makes it possible to print up to 200 pages of printed text. Cartridge refueling will not hit much on the budget. In such jet printers, the print head has a high resource compared to disposable jet cartridges.

Epson (this is not advertising) to the joy of users released a printer with a built.in branded system of continuously submitting ink (SNPC), one refueling of such a system is enough up to 1000 pages of printed text. The cost of use is quite adequate even when buying branded original ink. But you need to remember: so that the print head does not dry out, you need to periodically print something.

The jet has numerous advantages:

But the principle of printing with jet feeding paint has a number of disadvantages. The main disadvantages are low performance and expensive consumables. Therefore, jet more suitable for household or narrow use than office. Also, such devices allow you to print high-quality color pictures, they can work with CD discs, textured paper, which is not possible.

A jet printer device

The main component in the work of a jet printer is the print head, which is ink. This part is fixed on the carriage, which makes movements forward. forth across the sheet of paper, after which the coloring substance falls on the paper itself.

ATTENTION! The coloring substance cannot result, since the dozes have too small holes.

The work of this equipment is as follows: after the print task, a sheet of paper enters the printed compartment, in which it moves with the help of a promoting mechanism and at the same time is pressed against it with special rollers.

The principle of operation of the jet printer

The principle of operation of the jet printer is that the paint enters the sheets of paper in drip form through special nozzles. The size of each drop is very small and they come by squeezing.

Depending on the manufacturer, this equipment can print through several technologies:

  • Drop-on-Demand. A specially built.in mechanism in a tandem with a heating element sprinkles ink on demand so quickly that the quality and speed of printing improves significantly. During color printing, more contrasting and clear details of the image are obtained. This method is great for printing graphs and diagrams. they have clear lines.
  • Thermal method. An element is built into each duz that has the ability to heat up to a very high temperature, when electric current passes through it. This action contributes to the formation of gas bubbles, which displace paint on paper in the right amount. After turning off the current, the heating element cools and gives out a new portion of ink. The service life of printers operating this method exceeds the life of other devices operating at the expense of other methods. The disadvantage of this method is that during continuous filling, the image looks vague.
  • Piezoelectric method. This method lies in the fact that each nozzle has its own piecemeristal of a flat shape, which is directly associated with the diaphragm. When interacting with the electric field, it is deformed, that is, first it is compressed, and then unclenched, filling the system with ink. Thus, there are points on paper, which make up the whole image.

Continuous supply differs from the feed on demand in that the dye hit depends on the modulator.

The work of a jet printer

During the jet printing process, thousands of microscopic drops of ink are excreted through a series of nozzles in a printing head with a very high speed, forming an image on the page, what we already see ultimately. Despite a huge number of drops of simultaneously released from the print head, they are quite accurately applied to paper, when calculating the average print of the jet printer operating in a resolution of 300 points per inch, 2.475 points of 1/5000 are obtained. seconds per page.

To obtain a quick print and a high degree of detail, rich, bright images in jet printers, one of the types of printing is used: piezoelectric and thermal.

The piezoelectric method uses a small voltage inside the cartridge chamber to stimulate the material, as a result, this impulse drives droplets from the cartridge to the print head.

Thermal (thermal) method. The heating element is used that heats the ink, leading them to evaporation, as a result of which the bubbles create pressure in the cartridge cartridge, forcing liquid ink to move towards the snot of the print head.

You are still with us? We did not tire you tedious terms and chemical processes? We briefly examined how jet printers work, it’s time to switch to their advantages and disadvantages.

Advantages of printing on jet printers

Below we have brought the most common types of advantages of jet printers, bring you to understand what to expect from the purchase of a jet apparatus.

They are affordable in price

Given the huge number of producers of printers for jet printing technology, they became incredibly affordable. Take into account in recent years and analysis of the price of a jet printer, we can safely say that their price is from 1,500 to 5000 and this price range included not only the simplest cars, but also the All-in-One Printer, which will provide you with a full spectrum Opportunities for use.

Inkjet Printers | The interesting engineering behind them

They are easy to use

One of the largest advantages of jet printers. especially for home users. is the simplicity of their use. From the moment you open the box, download the cartridge and print your first document, you will not have any technical problems, which will allow you to enjoy a simple and qualitative seal.

They quickly get out of the waiting regime

Unlike some types of printers that require several minutes in order to warm up and bring themselves to the readiness mode before issuing the first print, inkjet printers do not need this! From the first moments they are already ready for work, about 5-7 seconds are required by a jet print to run the first page in print.

They print photos in great resolution

If you plan to print many color photos or graphic images, then you are on the right track. While laser machines print detailed images. Here the jet competes with accuracy, clarity and depth of color rendering, which unfortunately cannot laser printer.

They can print on any type of paper

Cardboard, gloss or matte surface of the paper, whatever type of it you call it, the jet printer can print on any. This flexibility gives them the opportunity to be ideal for art, crafts and other creative practitioners, which should regularly print on surfaces with different textures.

Laser and jet printer. differences in operational characteristics

When resolving the issue, which is better-laser or jet all-in-on-on printer for home use, not the first place is the money interest in the first place. We will study this side of the issue.

The comparative cost of the devices themselves and related materials is given in the table:

Index Inkjet printers Laser printers
For toner
Number of pages at one gas station 250-350 sheets up to 10 thousand

No printer works without consumables, so when choosing it is worth paying attention to the cost of servicing the device

Laser or jet all-in-on-print for home: print quality

Another important indicator is the quality of the receipt received. Modern models of jet printers that are “sharpened” for printing photos are able to issue an image with a resolution of up to 9600 × 2400 dpi, which provides the most complete detail of the picture.

Professional models of jet printers are used in printing to obtain high.quality full.color printing. Due to the complexity of mixing powder toner, a laser printer cannot work out photographic images with a similar quality, but its “skate” is the printing of the text. High accuracy allows you to make a breakdown even the smallest kegle, which when printing on a jet apparatus will simply smear. Also, the advantages of the laser print include the clearness of the resulting print and its resistance to the effects of external factors, such as sunny color and moisture.

Performance

According to this indicator, the palm of the championship belongs to laser devices for which there is absolutely no difference, the text or picture is printed, the speed of obtaining the print is maintained.

Powerful copy centers can provide print performance up to 120 pages per minute. In the jet devices for each individual pixel, its shade is selected, which affects the reduction of the print speed for the sake of the best quality of the finished image, if we are talking about photographs. In absolute values, the average print speed of a modern laser printer is 20-30 pages per minute. In the jet apparatus, this indicator is from 3 to 8 pages.

Environmental Safety

Almost no one pays attention to this factor, but in vain. It is proved that when the laser printer is spent in the air, ozone is released. This substance refers to the 1st group of danger, which means a low level of MPC. In its properties, ozone is more poisonous than carbon monoxide. An additional irritant is considered a powder, the smallest particles of which fall into the human respiration organs. Inkjet technique is deprived of such shortcomings. All coloring compositions are harmless to humans.

With significant printing volumes, the laser printer emits ozone, and the fine.dispersed toner powder can fall into the human respiration organs

Which is better: LED or laser printer

One of the new products of the printing market can be considered LED printers that have similarities with their laser analogues. According to the principle of operation, the difference between these devices is that for applying powder to the shaft, not a laser beam is used, but the LED ruler, equal in its width by the drum.

The LED printer outwardly no different from the laser analogue, but has a qualitatively different principle of operation

LED or laser printing. which is better

Experts admit that the quality of the print obtained by using the diode system is higher. This is due to the fact that in the laser printer to achieve a beam of the surface of the photo bus, you need to go a different path, leading to the difference between the distance between neighboring points. In addition, due to different angles of the fall of the beam, an oval, not a perfectly round marker, is formed. The LED system is deprived of such shortcomings due to the presence of a ruler on which the distance between the LEDs is the same, and the beam is not refracted, which allows you to get a perfectly round point. This ensures the preservation of accuracy in the center of the sheet and its edges.

The use of the LED ruler provides the best print quality due to the absence of a beam refractiveness

Which printer is better in performance: laser or LED

This indicator is also won by a LED printer in which the speed of work is practically not limited by using a diode line, where all light sources flare up at the same time. In a laser printer, with an increase in physical resolution, a linear distortion of the print line is observed, which gradually loses its horizontal orientation. With increasing print speed and high resolution maintaining in a laser printer, an installation of additional mechanisms is required, which leads to a rise in the cost of the apparatus.

The selection of the printer should be carried out in accordance with the aim of its further application. Which printer to choose: laser, jet, LED or even matrix. this is the subjective business of everyone. The most important thing is to objectively evaluate the scope of technology in the future. Based on this, you can choose a certain type of printing device. Once again, you can see the differences between laser and jet devices from the presented video.
