To start printing YouTube Analytics as a PDF, first, log into your YouTube account and go to the YouTube Studio. From the left-hand menu, select Analytics and adjust the time frame or data you're interested in. Once your desired metrics are visible, you can either take a screenshot or use the "Export" feature (if available) to download the data. If there's no direct export option, you can print the page by selecting Ctrl + P (Windows) or Cmd + P (Mac) and choosing "Save as PDF" in the print dialog. This way, you can save your analytics in a PDF format.
