Paginated reports in Power BI are designed for situations where you need a report that's optimized for printing or sharing as a PDF. Here's a breakdown of their key characteristics:

• Focus on Readability: They prioritize presenting data in a clear and well-formatted way, ensuring it fits well on a page, even if the data requires multiple pages.
• Printing and Sharing: They are ideal for scenarios where you want to generate printed copies of reports or share them as PDFs for offline viewing.
• Detailed Layouts: You have precise control over the layout of the report, including margins, headers, footers, and the placement of data elements.
• Data Source: While Power BI reports typically connect to real-time data sources, paginated reports can connect to various data sources, but the data itself is not live within the report.
• Separate Tool: Paginated reports are created using a separate tool called Power BI Report Builder, not directly within the Power BI service or desktop application.
