and then install Certificate.

au
thority is in progress (during the period starting from creation of CSR up
until installation of Certificate). If changed, the already issued Certificates
become invalid necessitating re-setup starting from the very beginning. If
printer setup is changed after Certificate is obtained, the “Security warning” is
displayed on the web browser.
I
