In the digital age, sharing files is as easy as clicking “Forward”. That’s why traditional PDF encryption — which simply locks a file with a password — is no longer sufficient to protect sensitive content such as training materials, academic documents, confidential reports, or copyrighted manuals. Once a recipient opens the file, there’s nothing stopping them from forwarding it, printing it to a PDF, or distributing it freely.
At VeryPDF, we often receive important and recurring questions from customers who want complete control over their documents even after delivery. This article responds to two such inquiries — from professionals David and John — and explains the difference between basic encryption and true Digital Rights Management (DRM), with a focus on how VeryPDF DRM Protector provides a secure, scalable, and reliable solution.
This is where VeryPDF DRM Protector comes in — a powerful document protection platform that offers fine-grained control, including a critical feature that many overlook: blocking printing to virtual PDF printers, which is one of the main loopholes in traditional DRM or encryption-based protection.
The Problem: Why Basic Protection Doesn’t Work
Let’s face it — a password-protected PDF is only as secure as the password itself. Once shared, the file can be opened, printed, and redistributed endlessly. Even when printing is allowed, users can simply use “Print to PDF” or install a virtual PDF printer to recreate a clean, unrestricted version of your document.
This loophole renders traditional protections almost useless. Users can:
* Print to a PDF printer and save an unprotected version.
* Use screen capture tools to copy sensitive content.
* Share links with others if access isn’t tightly tied to user identity.
* Bypass document expiration and usage limits if no proper DRM enforcement is in place.
Real Questions from Users — and Real Answers from VeryPDF
We recently received an inquiry from a user, Mr. Gil Choi, who raised some important concerns after testing our online demo of the DRM-protected PDF viewer.
Concern 1: “How can we prevent clients from re-sharing the file once they have access?”
Customer Message:
“We are worried that even though the files are encrypted, there is nothing in place to prevent our clients from re-sharing them once they have access. That is the solution we need.”
— David
This is a common misconception. When you encrypt a PDF file with a password using tools like VeryPDF Encrypt PDF, you’re only preventing unauthorized access. But once a user enters the password, they can:
- Forward the file to others
- Share the password
- Print the file to a virtual printer (like Microsoft Print to PDF)
- Take screenshots or copy content
There’s no lasting control over what happens after the file is opened.
✅ The DRM Solution: VeryPDF DRM Protector
To prevent forwarding and unauthorized reuse, you need a Digital Rights Management (DRM) system — not just encryption.
VeryPDF DRM Protector offers a full suite of controls:
| Feature | Description |
|---|---|
| User Authentication | Only registered users can open the file. Access can be revoked at any time. |
| Device Locking | Files are tied to specific computers or mobile devices. If a user shares the file, it won’t open elsewhere. |
| Online & Offline Modes | Files can be accessed securely even without internet, with optional sync verification. |
| Print Controls | Allow printing to physical printers only. Block virtual PDF printers completely. |
| Download Restrictions | Prevent saving or extracting the file. View-only mode is fully supported. |
| Dynamic Watermarking | Automatically stamp user ID, time, IP, or email on every page to discourage sharing. |
| Audit & Revocation | Track access and disable files at any time, even after distribution. |
This transforms your PDF into a controlled digital asset, where you dictate who can see it, where, and how.
Concern 2: “I want to allow printing — but block download and print-to-PDF”
Customer Message:
“The link says the document was expired. Also, I need to be able to print, but not print to pdf or download.”
— John
This is a perfect example of needing granular control over how users interact with a document. Gil’s requirements include:
- ✅ Allow physical printing (e.g., to an office printer)
- ❌ Disallow virtual printing (e.g., to “Print to PDF”)
- ❌ Disallow downloading the original file
Excellent point — and this is where our custom-built version shines.
In the demo version, printing is completely disabled to demonstrate the highest level of viewing security. However, in the customized version, we can:
-
Enable physical printing to real printers.
-
Restrict printing to virtual PDF printers, such as Microsoft Print to PDF or PDFCreator.
-
Track printing events including time, user, device, and printer name.
This approach gives you tight control: users can print hard copies for legitimate use but cannot generate new digital copies using virtual printers.
Why Blocking Virtual Printers Is Essential
In many industries — such as legal, education, publishing, or government — it’s not enough to just prevent printing. You must prevent the creation of clean digital copies via virtual printers. Without this, your content can be re-shared freely, defeating your protection efforts.
VeryPDF’s DRM engine includes virtual printer detection and can distinguish between real and virtual printing devices. Unauthorized output to any such printer is blocked silently or logged for administrator review.
Our Solution
- Updated Demo Link
We’ve refreshed the online demo to show our view-only protection in action:
View Demo File
(Username: Demo | Password: Demo)
This demo file:
- Cannot be downloaded or saved
- Cannot be printed (as it’s in strict view-only mode)
- Prevents copy, paste, screenshots (on supported platforms)
- Custom Version with Print Permissions
Once you proceed with a custom build, we’ll configure the following for you:
- ✅ Enable physical printing to selected printers
- ❌ Block print to PDF or other virtual printers using advanced driver-level detection
- ✅ Optionally watermark printed pages with dynamic metadata to track leaks
- ✅ Restrict the number of prints per user/device (e.g., allow only 1 hard copy)
- ✅ Disable downloading the PDF from the interface
Our approach ensures you get controlled printing, not uncontrolled duplication.
Standard Encryption vs. DRM: What’s the Difference?
| Capability | VeryPDF Encrypt PDF ($38 one-time) | VeryPDF DRM Protector (Custom Licensing) |
|---|---|---|
| Encrypt with password | ✅ | ✅ |
| Disable printing/copying | ✅ (basic) | ✅ (advanced) |
| Prevent sharing or forwarding | ❌ | ✅ |
| Bind to device | ❌ | ✅ |
| Revoke access | ❌ | ✅ |
| Track access logs | ❌ | ✅ |
| Expire documents automatically | ❌ | ✅ |
| Prevent print to PDF | ❌ | ✅ |
| Custom watermarking | ❌ | ✅ |
| Online demo available | ❌ | ✅ |
If you only need to encrypt internal documents, VeryPDF Encrypt PDF might be enough. But for protecting valuable content distributed externally — such as paid training guides, client files, or research reports — VeryPDF DRM Protector is essential.
Use Cases: Who Needs DRM?

Final Thoughts
PDF security is no longer just about passwords. As document sharing becomes more global and less traceable, you need lasting control over your files — not just before access, but after it too.
Whether you’re protecting a single eBook or distributing thousands of confidential files, VeryPDF DRM Protector gives you the power to say:
- Who can open your file
- Where and on what device
- How they interact with it
- And when that access expires
Don’t rely on outdated tools. Upgrade to a protection platform that truly respects your document’s value.
