You can make the PDF printer attach and send the output via email. It can open your email client and create a new mail ready for editing or it can send the mail automatically via SMTP.
If you check the email option on the general tab of the configuration dialog then it will try to use your default email client to open the new email.
Advanced options are available using settings in the configuration files. You can set the email client to auto (default), outlook, smtp, mapi, mapi32, or mapi64 to help it select the correct email client for opening or sending the mail. These and other advanced settings are normally set in the global.ini configuration file.
All the email settings are listed here: https://www.biopdf.com/guide/settings.php
The settings can be set directly in configuration files or via the Microsof.NET and COM programming interfaces.
If you experience that the printer is opening the wrong email client then you can try setting another via global.ini.
