On a computer

1. Press Print above, or Ctrl+P (Cmd+P on a Mac).
2. Pick A4 or US Letter in the bar above, to match the paper in your printer. The pages resize themselves, so leave Scale at 100% or Default.
3. Margins: None. The pages already have their own.
4. Turn off Headers and footers, or the date and web address print on every page.
5. Keep Background graphics on, so the colours and boxes print. Chrome and Edge: under More settings. Safari: Show details. Firefox: Print backgrounds.

To keep a PDF

1. Press Print.
2. Destination or Printer: choose Save as PDF.
3. Use the same paper, margin and header settings as above, then Save.

The file keeps the exact pages, and you can print from it as often as your licence allows.

On a phone or tablet

1. iPhone and iPad: tap Share, then Print. To keep a PDF, use the share button at the top of the print screen and choose Save to Files.
2. Android: in Chrome tap the menu, then Share, then Print, and pick your printer or Save as PDF.

Printing from a computer gives the most control over paper size and margins.
