What Is a Thermal Inkjet Printer?

Inkjet printers come in two primary technologies. They are continuous inkjet and drop-on-demand. The drop-on-demand category includes thermal inkjet (TIJ) and piezoelectric inkjet printers. Both of these technologies have a strong presence in the consumer market. CIJ or Continuous inkjet printers are functionally very different from drop-on-demand printers and are mostly in use for commercial purposes.

In comparison to the technologies and methods available in the market, thermal inkjet printers are a low-cost option for printing offering the advantages of a fast speed with a high-quality finish. TIJ printers are usable on a wide array of material surfaces such as regular and specialty papers, plastics, metals, and cartons. The first inks used water as the primary drying agent. Consequently, these units have been the best-suited option for printing on porous paper surfaces for many years. Currently, usage of alcohol or other solvent makes TIJ units suitable for printing on a wide range of materials including PVC, PET, blister foils, and varnish coated cartons. Development in recent times in the domain of ink and printheads technology is rapidly expanding the range of compatible materials that a user can print on.

Moreover, most of these printers require no training or practice and are very simple to use. Having no requirements of a warm-up or cool-down cycle, these machines are always available for use. An important distinction is necessary here. A thermal inkjet printer is not the same as a thermal printer. A thermal printer heats special paper to form an image on the paper. This printer type is in use by equipment that prints receipts and bar codes.

There are several reasons for the success of thermal inkjet printers. A primary aspect is that of ease-of-use. Moreover, a quick change of an ink cartridge implies a new ink supply and printhead are available for use. Moreover, ink is stored in sealed cartridges. This means no risks of spills or leaks. Also, as written above, they are affordable in comparison to machines that offer the same capabilities but use different technologies. Furthermore, TIJ printing provides excellent print results with high resolution and its growing ability of usage on various surfaces due to new ink developments offers great flexibility.


How Does a Thermal Inkjet Printer Work?

Despite not being the first ink-jet method to be in use as a product, it is the most successful method on the market today. The print heads in a thermal inkjet printer have, depending on the printer, 300 to 600 tiny nozzles that heat up the ink in the cartridge. This leads to the ink’s expansion and formation into a bubble. The ink from this bubble pushes through a nozzle onto the paper. During this process, the bubble pops and the air vacuum that forms due to the ink removal sucks more ink into the nozzles. Each of the nozzles has the capacity to apply ink simultaneously from black and white or color cartridges. Also, the print resolution can be adjusted downward if the highest resolution is not necessary for every printing task.

Although it is slower than commercial inkjet printers, the thermal inkjet printer is the most common form of an inkjet printer in households because of its affordability.

Where is a Thermal Inkjet Printer Used?

Printing needs arise in a variety of domains. With the global increase in urbanization and with its consequential impact, a multitude of industries are in need of marking or printing methods.


With regards to the industries that are using thermal inkjet printers, they can be segregated as follows:

● Dairy products

● Pharmaceuticals

● Household

● Food & beverage industry

●  Cosmetics and personal care


Thermal Inkjet Printer Market Trends

Manufacturers now have to implement anti-counterfeiting strategies, comply with strict regulations pertaining to labeling, and product traceability. As inkjet coders are non-contact printing coders used to print dates, batch numbers, and time on a variety of essential goods packaging, the market will remain relatively strong.
