Introduction to the Implementation
To achieve the goal of capturing print files using a virtual printer and uploading them to a server, follow these steps:
Step 1: Develop a Virtual Printer Program
A virtual printer operates just like a regular printer driver. Once installed, it appears in the list of available printers on the system, and third-party software can select it as a printing destination by clicking “Print.” The virtual printer performs two main tasks during printing: generating a PDF file and sending the document to a physical printer for actual printing.

Step 2: Develop a Program to Upload Print Files to the Server
This program functions as a service that runs continuously in the background. It monitors the system for new PDF files generated by the virtual printer. When it detects a new PDF file, it immediately uploads the file to a designated server.
Use Case Examples
1. Upload Print Content to a Server and Output to a Physical Printer (Example 1)
- Operating Environment: Windows 7/Windows 10
- File Format Conversion: JPG
- File Upload Protocol: HTTPS, POST
- Physical Printer Type: Thermal
- Number of Connected Physical Printers: 1
2. Upload Print Content to a Server and Output to a Physical Printer (Example 2)
- Operating Environment: Windows 7/Windows 10
- File Format Conversion: PDF
- File Upload Protocol: HTTPS, POST
- Physical Printer Type: Thermal
- Number of Connected Physical Printers: 4 (with different paper sizes)
3. Printer Driver Development
- Operating Environment: Windows 7/Windows 10
- Printer Type: Thermal
- Data Transmission: Serial Port
- Parameter Setting: Using the printer's SDK to set parameters
4. Controlling Printer Parameters Using PJL Commands
- Operating Environment: Windows 7/Windows 10
- Printer Type: Inkjet
- Data Transmission: Serial Port
- Functionality of Commands: Setting printer parameters such as grayscale, duplex printing, and number of copies
5. Correction of Print Content Offset
- Operating Environment: Windows 7/Windows 10
- Printer Type: Thermal
- Data Transmission: Serial Port
- Issue Description: Print content offset increases with the number of copies printed
Conclusion
By following the outlined steps, you can develop a virtual printer that captures print jobs, converts them into PDF files, and uploads these files to a server. This setup can be customized based on different use cases, such as supporting various file formats, communication protocols, and types of physical printers. Additionally, specific printer parameters can be controlled using PJL commands, and print content offset can be corrected to ensure consistent print quality.
