Printers are a well-known and used artifact in our day to day life. This is an accessory for computers with which we have the opportunity to print documents, images and much more . There are printers of all kinds that make life simpler; for example, multifunction printers often include scanners, copier, fax, and more. This device is really useful in everyday life and therefore it is important to know what the printer is for. Keep reading this post to know all the details about modern printers.

What is the printer for?

The main function of the printer is to transform a virtual medium into a physical object . In this way the virtual medium can be used outside the computer. We can print a text for physical archiving, or we can print a virtual 3D model to be used in reality.

Since its invention, the printer has evolved in many ways, but they still serve one key function: printing. We now have faster printers with better print quality. In addition to many new types of printers to work with specific things, such as photo printers or plotter printers. We even have 3D printers available to us, something that a decade ago looked like an artifact straight out of a science fiction novel.

Printer history

The printer was created around the same time as the first computer. This was so because the first computers lacked a monitor, and the information provided by it had to appear on paper. In the 1940s, the first fully functional printer appeared , weighing 2.5 tons. From that moment on, printers began to evolve, 10 years later we began to see printers more similar to what we now know; these were the first matrix printers.

Printer types

Thanks to technological advances we have better quality printers; And it’s not just the quality of the print that matters, but also the variety of equipment that exists to do specialized jobs. In general there are 3 types of printers, which we will see below.

Matrix or impact printers: These were the first printers created, those large equipment that we could find in offices. These models are currently obsolete; the print quality is not the best and the range of colors you can use is severely limited. These printers work with an impact system, somewhat like typewriters. A matrix of letters with ink impacts the sheet and what you need is reflected. To change the font or color, you must change the matrix.

There is another group within matrix printers called needle printers. These printers work by pressing a needle on a band of ink, thus carrying a transfer to the paper. Like the previous group, they are obsolete models with many limitations.

Inkjet printers : These types of printers work by generating a thermal or electronic pressure on the ink. Each electrical impulse generated by the printer software causes the internal head to embed a drop of ink with a predetermined shape on the paper. These printers are much faster than the previous model, plus they have much more facilities to adapt to any type of fonts and reveal more colors. In addition, with these printers it begins to be possible and in a simpler way the printing of images.

Laser printers : These are divided into two large groups, toner printers and thermal printers. These are the most used today. Much sharper resolution can be achieved in faster printing.

Toner Printers : These printers have a light and heat sensitive drum called toner. The printer produces an amount of heat in the form of a laser, which is processed by the toner transferring the necessary amount of ink to the paper.

Thermal printer : Unlike all previous models, the thermal printer does not work with ink. For these, a special paper known as thermal paper is used, which in contact with the laser causes what you want to print to darken.

What is a plotter and what is it for?

A plotter is a type of printer that can print on large-scale paper . These printers work with reels of paper of 1 meter of width or more; They are widely used to print architectural plans, banners, billboards and all kinds of documents that are larger than a sheet of A1 paper.

Printer parts

Since there are different types of printer, not all have the same internals. But we can generally describe the outside of the printer in the same way. These are parts of the printer that we can find in most models:

  • Paper holder
  • Sheet aligner
  • Outbox
  • Print head
  • Ink cartridge clamps, or failing that, toner
  • Control panel (power, print, maintenance buttons etc.)

What is the 3D printer for

3D printers are a new type of printers that allow us to create three-dimensional designs . These printers are a great technological novelty that has evolved really fast. These printers make a three-dimensional scan of what you want to print or build and create a model of some material, which varies depending on the type of 3D printer.

These printers have had a great impact in different sectors, since practically everything can be “printed”. In architecture, engineering, and industrial design, 3D printers are an excellent way to bring any design to three-dimensional reality. In addition, these teams have marked a before and after in many areas of medicine; With them, prostheses and specialized pieces can be created for each patient.

These printers work as follows; First, the three-dimensional model must be built on the computer, using a 3D design program. Subsequently, the model is printed. The printer scans the virtual model and proceeds to form a physical model with some material. These materials can be inks with additives, resin, polymers and compaction of dust particles.

Conclusion – Printer Brands

There is a wide variety of printer brands on the market. Each brand seeks to offer a type of printer according to the needs of each client. Among the best known brands is IBM , which was one of the brands that created the first matrix printers in the 1950s. HP is another brand that has made history in creating printers. Epson is currently a specialist in toner printers, but they have a wide variety of all types of printer. Apple has created great printers over the years. Other excellent brands include Kodak, Canon, Panasonic, Samsung , and many more.
