I'd like to know whether Nprinting 17.1 can Add domain users ？if can，how to do ?
Yes you can add domain users in Qlik NPrinting. Here you can find the instructions
Creating users with filters and groups ‒ Qlik NPrinting
and can I send a report to an email, but adding this user without domain\account? only email
You can just create an user without a domain. I created also test user with-out a link to an existing domain user.
Go to the admin section and choose User. Create there manual an user.
