I have installed Nprinting 17.0 in my server but due to some bug, I am not able to send the email via Nprinting. So I downloaded Nprinting version 17.3.
I don't know how to upgrade Nprinting version from 17.0 to 17.3.
Should it uninstalled Nprinting version 17.0 and then install version 17.3?
Will same license use in version 17.3?
Link to the User guide for version 17.3 or it has same user guide as of 17.0 ?
Please clarify me.
