PrintIT – Enterprise Reporting & Visualization Service for Visilean

PrintIT is a high-performance, standalone reporting and visualization service designed to generate
production-grade reports for Visilean without requiring any changes to the Visilean codebase.
Built using Java Spring Boot and React.js, PrintIT dynamically fetches Visilean data, renders advanced
visualizations such as Takt Time and Gantt charts, and produces print-ready reports ranging from A0 to A4 formats.

The platform enables organizations to preview, download, and distribute operational reports in multiple layouts (Tile and Article views), supporting both daily and weekly planning cycles with zero development effort from Visilean teams.

● Produces high-quality PDF reports using Aspose
● Supports preview-first workflows before final download
● Enables print-optimized layouts from A0 to A4 page sizes
● Works as a fully decoupled service with no Visilean code changes

Decoupled Integration Model

 

  1. PrintIT securely fetches required data from Visilean APIs
  2. Data is normalized and transformed internally
  3. Charts and layouts are rendered dynamically
  4. Preview is generated for user validation
  5. Final PDF is produced and delivered
    ➡ No code changes, deployments, or configuration required in Visilean
