The correct answer is A. Duplex .
In the CompTIA A+ Core 1 (220-1201) exam objectives under printer settings and configuration , duplex printing refers to printing on both sides of the paper automatically.
Using duplex printing is the best way to reduce resource consumption because:
It cuts paper usage in half , which is the primary resource being conserved.
It is ideal for multi-page documents and multiple copies .
It reduces physical storage and handling requirements.
Why the other options are incorrect:
B. Orientation
Orientation (portrait or landscape) changes the layout of the document but does not reduce resource usage .
C. Tray settings
Tray settings determine which paper tray is used (e.g., plain paper, letterhead), but they do not impact resource consumption.
D. Quality
Print quality (draft, normal, high) may affect ink/toner usage , but it does not reduce paper consumption as effectively as duplex printing, which is the main resource concern in this scenario.
Final Answer: A. Duplex
