How Developers Can Programmatically Control Print-to-PDF with Virtual PDF Printer API
Meta Description:
Easily add print-to-PDF functionality to your Windows app using VeryPDF's Virtual PDF Printer Driver SDK. Save time, boost output, and scale with control.
Tired of asking users to "Save As PDF"? Here's how I fixed it
Every time we rolled out a new version of our Windows app, the same support ticket would come flying in:
"How can I export this as a PDF?"
At first, we told users to print to PDF using the built-in Microsoft print driver. Then we realised that was a terrible experience.
They had to:
-
Click 'Print'
-
Select a printer
-
Name the file
-
Choose where to save it
-
And sometimes the file didn't even look right
It was clunky. It broke the flow.
So we needed something smarter a way to programmatically control the entire PDF output without bothering the user.
That's when I found VeryPDF Virtual PDF Printer Driver SDK.
Why I Chose VeryPDF's Virtual PDF Printer SDK
I wasn't just looking for a "PDF printer."
I wanted something I could embed directly into my app, automate completely, and customise to match our workflow.
This SDK nailed it.
It installs as a virtual printer inside Windows, but behind the scenes, your app can tell it exactly what to do where to save, how to name the file, whether to merge multiple documents, apply encryption, add watermarks everything.
I could print to PDF programmatically using code. That meant:
-
No user prompts
-
No file pickers
-
No missed steps
Just smooth, clean PDF generation from our app's print button.
What It Actually Does (And How I Used It)
Feature 1: Full Programmatic Control
You can automate:
-
File naming (using tokens like date, time, username, etc.)
-
File location
-
Output format (PDF, TIFF, JPEG, etc.)
-
Encryption settings (40-bit, 128-bit, 256-bit)
-
Print job redirection or shared printing
-
Combining multiple print jobs into one PDF
In my app, we batch-print reports nightly.
With VeryPDF, I set the output folder, named the files automatically by client ID and date, and merged multiple jobs into a single file.
Zero manual steps. Huge time-saver.
Feature 2: Cross-Language Compatibility
I work in C#.
My co-dev is a Delphi die-hard.
Another team's using Visual Basic.
VeryPDF's SDK supports them all even FoxPro. I didn't need to rewrite anything. It just worked with whatever language we threw at it. That's rare.
Feature 3: Silent Installation & Auto-Save
Here's the kicker: the silent install.
I could deploy the printer driver silently, pre-configure all the settings, and push it to 100+ endpoints with zero friction.
Plus, using the auto-save mode, the user never sees a prompt. Files are saved silently to a set location. This gave us total control over document management.
Who Should Use This SDK?
If you're a developer working on:
-
Document-heavy Windows apps
-
CRMs or ERPs with reporting modules
-
Legal, finance, or medical software
-
Point-of-sale or kiosk systems
-
Apps that run in Citrix or Terminal Server environments
then this SDK is your secret weapon.
Especially if you're tired of dealing with broken print workflows or frustrated users.
Why This Beats Other "Print to PDF" Options
I tried a few open-source libraries and even the built-in Microsoft driver. Here's what I found:
-
Microsoft's PDF printer isn't controllable by code
-
Other PDF libraries require you to build the document object by object (nightmare for complex layouts)
-
Some SDKs had poor multi-language or non-English Windows support
-
Many lacked silent install, merge options, or secure encryption
VeryPDF handled all of this out of the box.
It saved me weeks of development and gave me more control than any other option I tried.
Final Thoughts: This SDK Just Works
If your app generates files that users need as PDFs, stop making them do the heavy lifting.
VeryPDF Virtual PDF Printer SDK lets you take control.
You decide how PDFs are created, named, stored, and secured with full code-level access.
It's the tool I wish I'd found years ago. Now it's in every Windows app we ship.
