A developer spent two weeks battling html-to-docx and jspdf libraries, only to find them failing with modern CSS like Flexbox and Grid. Fighting the parser's limitations wasted more time than building the actual application. The core problem was forcing a library to interpret HTML, rather than using a tool that natively renders it.

The solution was to pivot to Puppeteer, a headless Chrome browser. Instead of converting HTML, it simply renders the page and prints it to a PDF. This approach guarantees 100% CSS support, correct layout rendering, and eliminates translation errors. The user sees exactly what the browser displays.

The implementation is straightforward: launch a browser, set the HTML content, and use the built-in PDF generation. This method leverages the world's most advanced rendering engine. For developers struggling with document libraries, using a headless browser is a more reliable and modern strategy for generating professional documents.
