Found a bug that seems to be an issue with at least the HP Universal Print Driver and the usage of the parameter "ShortInstallName" in the iprint.ini file.
If you set this parameter to anything other than DEFAULT, any attempt to create a Driver Profile will result in an error "The print driver is unknown".
So far in my testing - this has only occurred on the HP Universal Print Driver. I'm running the latest iPrint client (5.40) and the latest patches on OES2 SP2 (novell-iprint-server 6.2.20100312-0.6.1) and the iManager plugin (
Temporarily switching the iprint.ini parameter to DEFAULT - creating the driver profile - and switching the parameter back does seem to work as an interim workaround.
