  1. Check the page size in the Print Hub matches the paper in your printer (A4, A5, etc.).
  2. Widen the margins if content is being squeezed off the edge.
  3. In the browser print dialog, set Scale to 100% (not "Fit to page" if that shrinks oddly) and turn off the browser's own headers and footers.
  4. For very long prescriptions, print fewer sections at a time, or use Download PDF and print that.
