ITPEC IP October 2024 Question 23
ITPEC IP October 2024 — Question 23 of 100
An inkjet printer forms an image by ejecting very small droplets of liquid ink directly onto paper. Nozzles in the print head place colored or black ink at controlled positions. Thermal or piezoelectric mechanisms can generate the droplets, but the defining feature is non-impact deposition of ink onto the medium.
Answer (a)
Why not others:
- (b) describes an impact dot-matrix printer striking an ink ribbon with pins
- (c) describes a thermal-transfer method that melts or transfers ink with heat
- (d) describes electrophotographic laser printing using a photosensitive drum and toner
Key rule: Inkjet sprays ink, dot matrix strikes a ribbon, thermal printing uses heat, and laser printing uses toner and a photosensitive imaging process.
