Which type of printer utilizes heat to create ink bubbles that propel ink onto paper?

  1. Laser printer

  2. Dot matrix printer

  3. Thermal inkjet printer

  4. Line printer

The correct answer is: Thermal inkjet printer

The type of printer that utilizes heat to create ink bubbles that propel ink onto paper is the thermal inkjet printer. In this printer technology, electrical impulses heat tiny resistors located within the ink cartridge. This heating causes the ink to vaporize and expand, forming bubbles. As the bubble collapses, it forces a small amount of ink out of the nozzle and onto the paper. This process allows for precise drops of ink to be deposited where needed, producing high-quality images and text. Thermal inkjet printers are commonly used for their ability to produce vibrant color prints and detailed graphics, making them ideal for both home and office environments.
