Since your book is ready for printing, save it as a PDF file and send it to a service that can print Apple Photo Books from Pdf files.

See: Ordering Books and Calendars on a Mac that cannot be upgraded past El Capitan

Save your finished PDF book as a PDF file ( Check and review a project before you order using Photos on Mac - Apple Support) and then send it to a service that can print books from PDF files.

• Mimeo used to print for Apple and can handle PDFs created in Photos, see: https://import.mimeophotos.com
• Also Presto Photo can print from Apple https://www.prestophoto.com
• If you are not located in the US, there may be local printing services, which would be more economic with respect to international shipping fees and shipping time. In Germany we can use photographerbook to print existing Apple PDF files: https://www.w2p-photographerbook.de/fotobuch-aus-aperture-iphoto-fotos
