Weird, have not yet done SP6, I am running SP5, when I go into iManager
and try and upload drivers to the iPrint Broker it seems to be working, I
can click on buttons to upload from file/system, I can select the .inf
file, select the correct printer driver, it starts uploading to the
broker then after about two minutes I get this :

The XML page cannot be displayed
Cannot view XML input using style sheet. Please correct the error and
then click the Refresh button, or try again later.

System does not support the specified encoding. Error processing
resource ''. Line 1,...

Never had this issue before, everything else within iManager appears to
be working. thanks in advance for any help.
