+### Print to PDF
+
+`PrintingEnabled` must stay `true` (the default) for the browser's print-to-PDF path — including CDP's `Page.printToPDF` and Playwright's `page.pdf()` — to work.
+
+`PrintPdfAsImageDefault` controls whether each page is rasterized to an image before being placed in the PDF, rather than kept as native vector text and graphics:
+
+- `false` (shown explicitly below, and Chrome's default) — keeps text selectable and extractable in the output PDF. Use this if automation will read the PDF's contents afterward (text extraction, parsing, LLM ingestion) — image-based PDFs need OCR to get text back out.
+- `true` — rasterizes every page, which can look more consistent on pages with complex CSS or canvas content, at the cost of searchable text and a larger file.
