Printer Permission Issue in ProSheets (Failed to access print parameters)

Problem

If you receive an error stating: Unable to select Printer Printer Name or Failed to access print parameters, this typically points to a printer driver or permissions issue that prevents ProSheets from accessing complete printer information. Alternatively, it may indicate that no default printer is set on the system.

The Revit Print API works by first querying the available printers on the machine and then configuring the selected printer based on the format settings. Unfortunately, if any printer driver on the system is problematic, the Revit Print API may enter an error state. Even if the problematic printer is not actively in use, this error can still occur. Restarting Revit is often required to reset the error.

Solution

1. Identify the Default Printer
First, confirm that your system has a Default Printer. In Windows 10/11, there is an option called “Allow Windows to manage my default printer.” If this option is enabled, your system automatically sets a default printer. If this is disabled, manually assign a default printer from the list of available devices.

If the default printer is correctly set and the issue persists, proceed to identify the problematic printer driver by systematically disabling printers until the error clears.

2. Verify Printer Permissions
The user must have administrative permissions for the PDF24 Printer.
To enable permissions:

• Go to Devices and Printers.
• Right-click on PDF24 Printer and select Printer Properties.
• Navigate to the Security tab.
• Ensure the following options are enabled for your user:
  • Manage this printer
  • Manage documents

3. Additional Considerations
If your printers are created via a login script or group policy, the problematic printer may reappear with each login. If this occurs, contact your System Administrator for further assistance in identifying and resolving the problematic printer driver.

Several users have reported that the root cause of this issue was linked to a network printer. Identifying and disabling this printer often resolved the error.

By following these steps, you should be able to resolve printer-related issues when using DiRoots ProSheets and PDF24.

Why does ProSheets show “No Internet Connection”?

If you see the error “Please check your internet connection” while using ProSheets, here’s what it means and how to fix it:

Why this happens

• License Verification: ProSheets needs an active internet connection to validate premium subscriptions.
• Export Tracking (Free Version): Free users have a monthly export limit, which must be verified online.

If your internet is working but the error still appears, it’s usually caused by your firewall, proxy, or antivirus blocking ProSheets/Revit.

How to fix it

1. Check firewall/antivirus: Make sure Revit/ProSheets is not blocked.
2. Whitelist these domains:
   • *.diroots.com
   • *.dikeeper.com
   • dikeeper-prod-euw-api-app-eefmhef2hhevbsgr.westeurope-01.azurewebsites.net
3. Verify your connection: Confirm you can access other online resources while using Revit.
4. Check ProSheets logs (if the issue persists):

%localappdata%\DiRoots\ProSheets\Log

Share the log files with our support team for further analysis.

Special case: Offline environments

ProSheets does not work fully offline by default.
If your organization requires an offline license (e.g., for secure IT environments), please contact DiRoots Support. Offline activation is available only under specific conditions.

✅ After restoring internet access or adjusting your firewall rules, ProSheets should work as expected.
