The nw6.5 iprint documentation talks about the 'Remember password

I cannot see this option in any of my servers iprint.ini files.

Can anyone help?

(I have tried checking the box when installing a secure iprint printer

but the setting does not seem to be stored in the profile, I am
prompted for the password at next login (Zenworks4, MS XP, Client4.9,installing as a user printer without admin rights)
