Mass market computer inkjet printers appeared on the consumer market in the late 1980s. They had been under development for over twenty years by that time and by the mid-1970s, printer companies realized their technological potential. They could make dot matrix printers obsolete. But they had to be affordable and reliably create high-quality printouts.

Mass market computer inkjet printers appeared on the consumer market in the late 1980s. They had been under development for over twenty years by that time and by the mid-1970s, printer companies realized their technological potential. They could make dot matrix printers obsolete. But they had to be affordable and reliably create high-quality printouts.
Computer inkjet printers release very small droplets of ink onto paper. Today, all modern inkjet printers use color ink in addition to black. The cheaper color printers will use a combination of three colors: magenta, cyan, and yellow. All printers use black ink. These are the same three colors used in offset printing to produce four color prints.
Computer printer inkjet cartridges are expensive. It is like the old razor and razor blade marketing where they give you a razor and then charge the heck out of you for razor blades. But, this is how the world of consumables works. With inkjet printers, it seems that quality of graphics is higher than with text so when comparing inkjet printers for purchase always compare how they print text as well as the color graphics.
High-quality coated paper stock will enhance the appearance of your computer inkjet printout. These coated pieces of paper will not absorb the printer ink in the same way that the ink is absorbed by standard printer paper. While coated paper is more expensive, the cost should be considered when you are about to purchase ink for your printer. If you need to print high quality images to be used for advertisements, you need a wide-format printer. These printers are used to produce big text and graphics for large posters, billboards, or banners. In addition to printing images on paper, these printers can be used to print images on other materials such as vinyl. These professional grade printers and often used in businesses and industry.
The way in which ink is printed on materials falls into two categories: "drop on demand" and "continuous ink." As the name suggests, printers using the continuous ink method will spray droplets of ink continuously onto the material. While this method is still common, drop on demand will force the ink out of the chamber by using electricity or heat. A thermal technique is used to warm up a small resistor than will push the droplets out of the nozzle. An air bubble will be generated within the chamber. Some companies have also started using crystals to expand the ink. This is one of the new advances in printer ink technology.
