Print settings checklist

  • Export a PDF from PhotoSheet Pro at the paper size you will load.
  • In the print dialog choose Actual Size or 100% scale.
  • Turn off Fit to Page, Scale to Fit, and “shrink to printable area”.
  • Select the matching paper size in the printer tray settings.
  • If using borderless, expect slight overscan crop — add a small margin if edges matter.
