Product

Device & OS
not provided
Scenario
Attempting to open and print online coupons from SmartSource using a PDF viewer.
Observed behavior
The PDF loads as a blank page or throws a printing disabled error, and the user cannot bypass or modify the security settings due to a blocking modal trust dialog.
Before you start

Ensure that your web browser and PDF reader are updated to their latest versions, as outdated plugins frequently cause DRM-protected coupon formats to fail during loading.

Solution 1Recommended

Add SmartSource to Privileged Locations to Trust the PDF

Use this solution to manually bypass the modal trust dialog block by adding the coupon provider's host URL or folder to your trusted locations in the PDF reader.

Sometimes a security dialog closes before you can click 'Trust this document', preventing the print function from activating. Adding the domain to your privileged locations allows the coupon script to run securely.

1
Open Preferences

Launch your PDF reader, click on the 'Edit' menu at the top, and select 'Preferences' from the dropdown list.

2
Navigate to Enhanced Security

In the left-hand panel of the Preferences window, select 'Security (Enhanced)'.

3
Add Trusted Location

Under the 'Privileged Locations' section, click 'Add Host' and enter the SmartSource URL, or click 'Add Folder' if the temporary coupon PDF is saved locally. Click 'OK' to save the settings.

4
Restart and Print

Close the PDF reader and your browser, then reopen the coupon link to try printing again.

Important: If you are using macOS or Windows, ensure your default printer is correctly configured before attempting to print the coupon.

Frequently Asked Questions

Why are my PDF coupons printing as blank pages?

Blank printing usually occurs due to outdated PDF reader plugins, browser compatibility issues, or restrictive document security settings that block the rendering of the print content.

How do I bypass the 'printing is disabled' error in a PDF?

If the document restricts printing, you must either click 'Trust this document' when prompted by the security dialog or add the document's source to the privileged locations in your PDF reader's security settings.

Can I use a different browser to print SmartSource coupons?

Yes, switching to a different web browser or clearing your current browser's cache often resolves plugin loading errors and trust dialog issues associated with SmartSource coupons.
