WHERE did it ell me Apple did not support this anymore no where
\
It's more a question of "when" than "where". I have seen the alert in iPhoto and Photos in August, when there was still time to finish the projects and order them. But Apple seems to have removed it now.
If you can still have the original Apple projects, save the projects as a PDF, then upload the PDF to Presto Photos or Mimeo and have it printed this way. In Germany, you can also upload to photographerbooks.
