I do read from some tech note. The iprint using http:xxxx:631 can also

accept nds user auth if the security is set up medium (default).

Where can I set the nds user auth, I launch the iprint client and also

check the printer properties from the printer in the control panel,
none
of them can set the user info. when I start to print to the ipp
printer,
it print successfully without any user auth with medium setting of
security. seems like anyone can print to my printer from internet,
very
unsecure.

I didn't reserve the 443 port for security printing when I install the

nw6. Anyway I can add it back now?
