If your application needs to convert documents into PDF programmatically, automate PDF creation through a virtual printer, or embed silent PDF printing features directly into your own software, the VeryPDF Virtual PDF Printer SDK is one of the most powerful and flexible solutions available. Designed specifically for software developers, system integrators, and enterprise IT teams, this SDK offers reliable PDF generation, customizable virtual printer deployment, and seamless integration into Windows desktop or server products.
1. Overview of VeryPDF Virtual PDF Printer SDK
The VeryPDF Virtual PDF Printer SDK enables developers to install a fully functional virtual PDF printer inside their own applications. Once installed, the printer appears in Windows like a standard printer device. Any application capable of printing—Microsoft Office, web browsers, engineering systems, ERP solutions, or legacy Windows software—can output directly to PDF using this virtual printer.
The SDK provides a complete programmatic interface that allows developers to:
- Generate PDF files silently (no dialogs or user interaction).
- Customize printer name and branding (OEM edition).
- Automatically save PDF to pre-defined folders.
- Trigger external scripts or executable files after PDF creation.
- Integrate with document workflows, DMS/ECM systems, and cloud storage.
- Package the virtual printer inside their own MSI or EXE installers.
This makes the SDK ideal for PDF automation, batch PDF generation, document archiving, and application-embedded PDF output.
2. Key Features and Benefits
2.1 Silent PDF Printing (Zero User Interaction)
One of the most important features for developers is the ability to generate PDF files programmatically without showing any dialog boxes. Using the configuration file or API, you can define:
- Output directory
- File naming rules
- Auto-overwrite behavior
- Background (silent) printing mode
- File save templates
This enables unattended PDF creation, essential for server environments, scheduled jobs, RPA workflows, or automated document management systems.
2.2 Custom Branding and OEM Printer Naming
The SDK supports full co-branding, allowing you to integrate the virtual PDF printer as if it were your own product:
- Custom virtual printer name
- Custom driver name
- Custom installer name
- Custom printer description (shown in Windows)
This feature is available with the OEM License, making the printer indistinguishable from your own software component.
2.3 Automated Workflow Actions (Post-Processing)
After a PDF is generated, the SDK can automatically launch:
- Any executable (
.exe) - Batch file (
.bat / .cmd) - PowerShell script
- File uploader
- OCR processor
- Document indexing tool
This is ideal for PDF conversion pipelines, ECM ingestion, cloud upload tasks, and custom automation scripts.
2.4 High-Quality PDF Output Using DynaPDF Engine
The SDK uses the powerful DynaPDF library, ensuring:
- High-fidelity PDF rendering
- Accurate fonts and formatting
- Excellent compatibility with Windows print outputs
- Fast and stable performance
Zlib compression is also included for optimized file sizes.
2.5 Modular Architecture (Optional Components)
To minimize installer size and optimize deployment, optional modules can be included only when required:
| Optional Folder | Description |
|---|---|
| pdf-security-signature-cmd-sdk-com | PDF encryption, password protection, digital signatures |
| pdf2image_win | Convert PDF to image (PNG, JPG, TIFF, BMP) |
| pdfprint_cmd | Advanced PDF printing (duplex, grayscale, N-up, page ranges) |
| pdfstamp_cmd | Watermarking, stamping, headers/footers |
| pdftotext | PDF text extraction |
| curl | Upload generated PDFs to your server |
| Server | Server storage integration |
With this modular design, developers can build lightweight installers customized to their needs.
3. Minimal Deployment Guide (Smallest Possible Installer)
Many developers want to reduce the size of their MSI or EXE installer. Although the full VeryPDF-PDFPrinter directory includes many sample tools and optional components, only a few files are required for basic PDF printing functionality.
3.1 Required Files for PDF Printing Only
To supports PDF printing only, include ONLY these files:
config.ini
data.dat
XXXXpdf.dll
install-printer.bat
install-printer.vbs
mfilemon-setup.exe
pdfconfigcmd.exe
zlib.dll
bin/RunAsUser.exe
These components include:
- XXXXPDF engine (XXXXpdf.dll)
- Virtual printer configuration tools (pdfconfigcmd.exe, config.ini)
- Printer monitor installation utility (mfilemon-setup.exe)
- Silent printer installer scripts (bat & vbs)
- Privilege elevation helper (RunAsUser.exe)
With only these files, you can fully install and use the Virtual PDF Printer.
4. Installation Methods
4.1 Installation with Administrator Privileges
If your setup program runs with elevated permissions:
install-printer.bat
This installs the virtual printer quickly and silently.
4.2 Installation Without Admin Privileges
If the user does not have admin rights:
install-printer.vbs
The VBS installer uses a per-user installation method, making the SDK compatible with restricted or domain-controlled environments.
5. Packaging the SDK in Your Own Installer
VeryPDF provides clear instructions and sample scripts that help you:
- Embed the virtual printer into your MSI / InstallShield / WiX / NSIS / Inno Setup installer
- Install the printer silently during your software installation
- Deploy necessary DLLs and configuration files automatically
- Remove unnecessary components to minimize installer size
This makes the SDK suitable for commercial software products that need a reliable and legally redistributable PDF printer engine.
6. Common Integration Use Cases
6.1 Document Management Systems (DMS / ECM)
Automatically convert any printable document into PDF and store it in a repository.
6.2 ERP and Accounting Software
Generate PDF invoices, purchase orders, financial statements, and reports.
6.3 Workflow and Automation Systems (RPA, BPM)
Batch-convert documents into PDF as part of automated workflows.
6.4 Cloud-Based Applications
Generate PDFs client-side and upload them to the cloud automatically.
6.5 Custom Desktop Applications
Embed PDF creation without requiring Adobe or third-party applications.
