1.3.4 (a): describe the principles of operation of inkjet printers and describe how they are applied to real-life scenarios

Components of an inkjet printer:
-A print head consisting of nozzles which spray ink droplets on paper to form characters/images.
-Ink cartridges 
-A stepper motor and belt which moves the print head across the paper
-A paper feed which feeds the printer

Thermal bubble:
-Tiny resistors create heat, making ink vaporise.
-The ink forms a tiny bubble which expands. causing some of the ink to land on the paper from the print head. 
-The bubble collapses and a small vacuum is created, allowing new ink to be drawn into the print head.
-This continues until the print job is complete

Piezoelectric:
-A crystal, located at the back of the ink supply for each nozzle, is given a tiny electric charge, causing it to vibrate.
-The vibration causes ink to land on the paper from the print head. 
-Meanwhile, more ink is drawn in for the next print.

Principles of the ink-jet printer:

Uses of inkjet printers:

-They are best for printing good quality one of photos
-This is because of the small sizes of ink cartridges and paper trays, so there would be no issues.
