Understanding QuickBooks Error 20 and Basic Troubleshooting Steps - errorcodeexperts - 11-25-2025

QuickBooks Error 20 is a common printing-related issue that users may encounter while operating desktop versions of the software. This error typically appears with a message stating “Error -20: Printer not activated”. While it’s frustrating, it’s usually related to outdated system settings, printer configuration issues, or changes made to Windows registry entries after a system update. Although it looks technical, this error can often be resolved with a few structured troubleshooting steps.

This error primarily occurs when the QuickBooks application cannot communicate with the default printer, PDF converter, or other required system components. In many cases, changes from Windows upgrades (such as moving from Windows 7/8 to Windows 10 or after a feature update) can remove or modify necessary registry permissions. As a result, the software loses permission to execute print functions and triggers QuickBooks Error 20.

One of the first things users should do is verify whether the printer setup is working normally. For example, printing a test page outside of QuickBooks helps confirm whether the issue is software-based or printer-related. If the printer works fine but the error still shows up inside the software, then the root cause is likely linked to system configuration rather than the device itself.

Another common reason behind QuickBooks Error 20 is outdated or missing print drivers. Ensuring that printer drivers are fully updated and compatible with the operating system can help restore printing functions. Users may also need to reinstall the QuickBooks PDF Converter tool, which plays a key role in enabling printing, emailing forms, and generating statements inside the software.

User account permissions may also be part of the problem. Running the software with administrator access can sometimes fix the issue instantly, especially if recent system updates limited application access. In addition, ensuring that registry keys related to print services are properly configured can also help prevent recurring errors.

If basic troubleshooting does not resolve the issue, uninstalling and reinstalling the software can sometimes help restore default printing configurations. However, before making major changes, it’s always smart to create a backup of data files to prevent accidental loss.
While QuickBooks Error 20 can be inconvenient, it is generally fixable without requiring advanced technical knowledge. Understanding the underlying causes—such as outdated drivers, incorrect registry settings, or permission conflicts—can help users apply the right approach and avoid unnecessary system disruptions. Regular maintenance, keeping software updated, and avoiding sudden operating system changes without compatibility checks can help minimize the chances of this error appearing again.

In conclusion, QuickBooks Error 20 is a relatively common issue tied to printing functionality, but with the right steps and system adjustments, users can resolve it efficiently. Proper configuration, updates, and system permissions often make the biggest difference in preventing and resolving the error.
