The "bubble-jet" name refers to the physical process used to propel ink from the printhead. Unlike piezoelectric printers that use mechanical vibration, bubble-jet printers rely on :
: As the heater cools, the bubble collapses, creating a vacuum that pulls fresh ink from the reservoir into the chamber for the next cycle. Key Advantages and Disadvantages
: Dries quickly and is less sensitive to humidity. bubble-jet printer
: The constant "cavitation" (extreme heating and cooling) can eventually damage the heater surface over time.
: The lack of bulky mechanical transducers allows for smaller, portable printhead designs. Disadvantages : The "bubble-jet" name refers to the physical process
The adoption of bubble-jet technology was driven by several functional benefits, though it carries specific trade-offs compared to modern laser or piezoelectric alternatives. :
: These printers are generally cheaper to manufacture and purchase initially than laser printers. : The constant "cavitation" (extreme heating and cooling)
While bubble-jet printers can use standard paper, specialized "PB paper" was developed to optimize ink absorption and reduce bleeding. For higher-quality results, users often employ:
