Any restrictions for automatic printing from email?

[OM2]

I need to have certain emails printed automatically as soon as they are received. Ideally onto a Bluetooth printer.

I've searched and searched. Nothing us available. ☹️

I want to try and get something developed myself. I'll work with a freelancer.

Just wanted to know, is there any restrictions that would stop automatic printing?
Like maybe security restrictions?
Ideally, I would like to print from Gmail app.

Otherwise, a standalone email app is fine as well.

Just wanted guidance before I spend time and effort.

Thanks.

Well you would need an app such as Tasker, https://play.google.com/store/apps/details?id=net.dinglisch.android.taskerm and a printer app such as
