High-volume printing capabilities.
Sharp text quality.
Lower cost per page compared to inkjet printers.

Disadvantages:
Higher initial cost.

Can print multi-part forms (carbon copies).
Low operating costs

Disadvantages:
Noisy.
Low print quality and slow speeds.

Question 4

LED Printers

Answer 4

Advantages:
Fewer moving parts, potentially more reliable.
Fast and efficient.

Disadvantages:
Print quality may not be as high as laser printers.
