I just noticed TID 3786843 which recommends hotfixes for Windows SP

Novell recommends that every Windows 2000 SP4 and XP SP2
workstation running the iPrint client have two Microsoft
hotfixes applied....
1) Install Microsoft hotfix KB 884897 - Missing print features
2) Install the Microsoft hotfix KB 893225 - Slow print performance

I have noticed that "n-up" printing does not seem to work with iPrint.

Has anyone done this with good/bad results? It appears that you have to
beg Microsoft support for access to these, as I can find the discussion
of them on the Microsoft web pages, but not the download itself.
