how a thermal bubble inkjet printer works


Printing technology has come a long way since the days of the dot matrix printer. Today, there are many different types of printers, each with its own set of advantages and disadvantages. One type of printer that is becoming increasingly popular is the thermal bubble inkjet printer. In this article, we will take a closer look at how thermal bubble inkjet printers work.

What is a Thermal Bubble Inkjet Printer?

First of all, let's define what we mean by a thermal bubble inkjet printer. An inkjet printer is a type of printer that produces images by spraying tiny droplets of ink onto paper. A thermal bubble inkjet printer, as the name suggests, uses heat to create these droplets of ink.

The technology behind thermal bubble inkjet printers was invented in the late 1970s by Canon. The idea was to use heat to create bubbles in the ink, which would then be forced out of the print head and onto the paper. This process is known as thermal inkjet printing.

How Does Thermal Inkjet Printing Work?

Thermal inkjet printing works by heating up a small amount of ink in a tiny chamber located inside the printer's print head. The ink is heated to the point where it vaporizes and forms a bubble. This bubble then expands rapidly, forcing a tiny droplet of ink out of the print head and onto the paper.

The amount of heat required to create the bubble is controlled by a heating element located inside the print head. The heating element is made up of a tiny resistor that is heated up by an electric current. The amount of current flowing through the resistor determines how much heat is generated, and therefore how large the bubble is.

Once the ink droplet has been formed, the print head moves across the paper, depositing thousands of tiny droplets of ink in the appropriate pattern to form an image or text.

What are the Advantages of Thermal Bubble Inkjet Printing?

There are several advantages to using thermal bubble inkjet printing over other types of printing technology. Here are just a few:

1. High Quality Output

Thermal bubble inkjet printers are capable of producing high-quality images with vivid colors and sharp detail. Because the droplets of ink are so small, the resolution is high, resulting in crisp, clear images.

2. Low Cost

Thermal bubble inkjet printers are relatively inexpensive to manufacture, making them an affordable option for home users and small businesses.

3. Easy to Use

Thermal bubble inkjet printers are very easy to use. They require very little maintenance and can be set up and used right out of the box.

4. Versatility

Thermal bubble inkjet printers can print on a wide variety of media, including glossy photo paper, vinyl, fabric, and more. This makes them a versatile choice for a range of printing applications.

5. Energy Efficient

Thermal bubble inkjet printers are energy efficient, using only a small amount of electricity to heat the ink and create bubbles. This makes them an environmentally friendly option for those looking to reduce their carbon footprint.


In conclusion, thermal bubble inkjet printers are a great choice for those looking for an affordable, high-quality printing solution. They are versatile, easy to use, and produce stunning images and text. Whether you're printing photos, documents, or artwork, a thermal bubble inkjet printer is definitely worth considering.
