Answer 1

SMTP protocol is used to simple email messages. Just find any C++ SMTP client and connect it to a SMTP server.

You could use Gmail or Outlook. But, personal email address usually gets flagged as spam if you send out too many emails. Also, people can usually send emails to it. It's not the best experience.

You could use a dedicated service provider such as Mailgun or SendGrid. You could set up your own SMTP server but I would suggest strongly against it. It can get very complicated to set it up secure and reliable.

You can also send good looking website like receipts using HTML.

Either way, make sure that you use TLS to encrypt the messages and have a certificate installed. Modern email clients doesn't like it otherwise.

There are also some requirements to avoid your email going straight to spam. Just Google "email avoid spam" and follow the checklist.

Answer 4

The email based one is pretty straight forward. There are plenty of examples for sending email with C++ using an email server.

For paper receipt, you will need a printer with open source drivers or public APIs. Once you find one, then it's just API calls.
