When print management for a specific vendor is configured to send an email once a PO is confirmed, a confirmation journal has to be generated so the email can be sent by enabling the following toggle button when generating the confirmation "Use print management destination".

However, when a PO is confirmed in POS, it does not generate a confirmation journal, so the email is not sent.

We suggest giving the option of generating a confirmation journal while confirming a PO in POS to honor the print management settings for sending emails etc.
