There is currently no option in the print management setup to define the email body for purchase confirmations.
However, I can suggest a workaround that doesn't require any customization, provided your customer agrees to it. You can create a workflow for purchase confirmations, set it to auto-approve, and define the email template with the body content. This way, an email will be triggered automatically once a purchase order is approved and confirmed.
