how do you print an entire notebook in OneNote?

I can only print one tab at a time, but I want all tabs printed

If you are talking about printing a range of notes within a section:

To select adjacent notes for printing, click the first note tab in the
sequence, hold down SHIFT, and then click the last note tab.

To select nonadjacent notes for printing, click one note tab, hold down
CTRL, and then click each additional note tab.

Then Ctrl+P to print.

The easiest way is likely to be to publish the entire notebook as a PDF,
then print the PDF.
