Answer:
Step-by-step explanation:
Thermal bubble and piezoelectric are two different types of inkjet printing technologies.
Thermal bubble technology works by using a heating element to rapidly heat a small amount of ink, causing it to vaporize and form a bubble. The pressure from the expanding bubble forces the ink through a small nozzle onto the paper. Thermal bubble technology is commonly used in consumer inkjet printers due to its relatively low cost and simplicity.
Piezoelectric technology, on the other hand, uses a small crystal that deforms when an electric current is applied to it. This deformation creates a pressure wave that forces ink out of a nozzle and onto the paper. Piezoelectric technology is more precise than thermal bubble technology and can produce smaller droplets, which can result in higher quality prints.
In summary, thermal bubble technology uses heat to vaporize ink and create a bubble to eject ink from a nozzle, while piezoelectric technology uses electrically induced pressure waves to force ink out of a nozzle. Piezoelectric technology is generally considered to be more precise and produce higher quality prints, but it is also more expensive and complex than thermal bubble technology.
