System Printer vs Nonsystem Plotter in AutoCAD
AutoCAD can use operating-system printers and certain nonsystem/HDI plotter configurations. Modern CAD offices should understand the distinction before choosing old HP-GL/2 or PostScript-style workflows.
In one sentence: Use the system printer path for modern supported hardware unless a specific nonsystem workflow is required.
What the term means in a CAD plotting workflow
Autodesk distinguishes Windows system printers from nonsystem plotters configured through AutoCAD’s Add-a-Plotter tools. PC3 files can represent either type of configured plotting path.
Why it matters for AutoCAD users
- System printers use manufacturer/OS drivers and are the normal path for current devices.
- Nonsystem drivers can support legacy/emulated HP-GL/2, PostScript/EPS and other file/device workflows.
- Choosing a nonsystem driver changes what capabilities and media information AutoCAD can see.

Practical decision workflow
Step 1 — Identify real hardware
Where: Manufacturer support
Do this: Check current supported driver.
Check: Know whether OS supports device.
Step 2 — Use system printer first
Where: OS + AutoCAD
Do this: Install/select manufacturer driver.
Check: Basic plotting works.
Step 3 — Use nonsystem only for reason
Where: PLOTTERMANAGER
Do this: Choose HP-GL/2/PostScript/etc. only for a documented workflow.
Check: Purpose is explicit.
Step 4 — Create PC3
Where: Add-a-Plotter
Do this: Name by technology/device.
Check: Users know path.
Step 5 — Compare output
Where: Calibration sheet
Do this: Test scale, raster, fonts and linework.
Check: Chosen path is justified.
Typical problems and the first place to look
| Symptom | Most likely hardware/driver layer | First check |
|---|---|---|
| Raster missing in HP-GL | Driver limitation | Use appropriate driver. |
| Modern HP DesignJet poor/odd behavior with generic HP-GL/2 | Wrong path | Use HP system printer. |
| EPS needed | PostScript file PC3 | Use deliberate file workflow. |
| Nonsystem media names differ | Driver model | Do not assume system-printer papers. |
Practical example
A modern DesignJet works through the HP system printer, while an old emulated device still requires a nonsystem HP-GL/2 PC3. Keep those as two explicitly named workflows rather than assuming the older nonsystem path is inherently more ‘CAD-correct.’
Good office standard
Prefer manufacturer-supported system printers for current hardware. Keep nonsystem configurations only for controlled legacy/emulation/file-output purposes.
What this does not mean
Nonsystem does not mean ‘more professional’ or ‘more accurate’; it simply means AutoCAD is using its own driver/configuration path rather than an OS system printer.

Frequently asked questions
What is the normal choice for a current large-format printer?
Start with the current manufacturer-supported operating-system printer driver. Use a nonsystem AutoCAD driver only for a specific supported legacy, emulation or file-output workflow.
Does nonsystem mean more accurate?
No. It only describes the driver/configuration path. Accuracy depends on the actual device, driver, media and tested Page Setup.
Can a PC3 represent a system printer?
Yes. AutoCAD can create a PC3 configuration based on a system printer so AutoCAD-specific settings can be standardized.
