We rely on the browser’s print feature to create the PDF. Every browser does this a bit differently, so you may have mixed results depending on your browser.
We recommend exporting your notes and insights to PDF with Google Chrome, since it seems to create the best output file.
Remember to open the note or insight as a page before printing, otherwise the text outside of the modal dialog will get cut off.
We're aware of an issue where some tags don't appear in the sidebar when exporting long notes to PDF and are investigating possible solutions.
