Computer graphics hardware: which of the following is primarily a graphical output device used to produce vector or large-format drawings?

Introduction / Context:
Output devices convert digital information into human-readable form. In engineering and design, “graphical” often refers to devices capable of accurate vector output, wide formats, or precise line work suitable for CAD drawings, schematics, and architectural plans. Understanding each device’s core purpose helps select appropriate tools for technical documentation.

Given Data / Assumptions:

• The goal is to identify a device designed for graphics-oriented output.
• Plotters historically draw continuous lines with pens; many modern large-format plotters are inkjet but remain optimized for graphics/CAD.
• Dot-matrix, line, and general laser printers are primarily text/bitmap devices, though they can print images.

Concept / Approach:
Traditional plotters (pen or modern large-format) excel at precise line drawings, vector paths, and scaled technical graphics. While laser and dot-matrix printers can render images, they rasterize content and are optimized for text or general documents rather than precision vector plotting at large scales. Line printers are strictly text-oriented high-speed devices.

Step-by-Step Solution:
List candidate devices and their primary design intent.Match “graphical output device” with equipment optimized for vector/large-format drawings.Choose “Plotter” as the best fit.

Verification / Alternative check:
CAD workflows have long used plotters for blueprints, plan sets, and schematic plots due to accuracy, scale, and line quality.

Why Other Options Are Wrong:
Dot-matrix (A) produces low-resolution text/graphics. Laser printer (C) is versatile but not specialized for large-format vector output. Line printer (D) targets high-volume text only. “None” (E) is invalid because a correct choice exists.

Common Pitfalls:
Assuming any printer that can print a picture is a “graphical device.” Precision plotting for CAD needs different mechanics and formats.

Final Answer:
Plotter.
