Set Print Titles with Python.NET

Possible Usage Scenarios

Setting print titles in Excel ensures that specific rows or columns are repeated on every printed page, which is especially useful for large spreadsheets that span multiple pages. Here are some reasons to set print titles:

1. Enhanced Readability: Print titles help readers understand the data by keeping headers visible on all pages, making it easier to interpret the information on each page without having to refer back to the first page.

2. Professional Presentation: Consistently displaying headers or labels on each page creates a more polished and professional appearance for printed documents.

3. Improved Navigation: For documents with extensive data, repeating the headers on each page allows for quicker navigation and reference, reducing the need to flip back and forth between pages.

4. Reduced Errors: When headers are present on every page, they minimize the chances of misinterpretation or data‑entry errors, as users can easily see the context of the data.

5. Consistency: Ensuring that important information, such as column headers or row labels, is always visible maintains consistency and clarity throughout the document.
