Lesson notes

Learning Objectives

Indicator: B8.1.1.1.3 - Examine the uses of the output devices: Braille printers, Impact, Inkjet, Thermal, Wax, 3D printers

By the end of the lesson, learners can:

Identify at least four of the six output devices (Braille, Impact, Inkjet, Thermal, Wax, 3D) from pictures or descriptions.
Describe the basic features of each output device, including what it prints on and how it produces output.
Match each output device to its real-life use in Ghanaian settings (for example, receipts in shops, labels on products, braille materials for visually impaired learners).
Explain the difference between impact and non-impact printers, and between 2D and 3D output.
Choose an appropriate output device for a given real-life task and justify the choice.
