I think I know what it might be - it just twigged me.

Edit the Additional Form specification in the designer, and go to the File menu and Specification Options. A default of 55 details per page is set and you might need to change this to a different (smaller?) number to fit your printer driver. You may also need to edit/adjust the section sizes for the advice header, detail and footer.

You could try previewing the form within the designer and to the same printer driver while determining what works.

Any Adagio form won't preview or print any pages if too much information is set to be printed on a single page. For example, if the total height of a page header and footer exceeds the page length.
