I "upgraded" my iPrint appliance from 0.0.377 to by iprintconfig.zip. First I thought it went well, today I noticed that nearly all printer driver profiles are gone. The printers are still assigned with that profiles, but if I try to edit one of the profiles, I get an error that it is not found.
Therefor, I can`t install printers ...
To make my environment running again, I removed the association printer - driver profile. I fear I have to recreate all profiles for all OSs again :-/

Where are that profiles stored? Just in eDir or files? If files - where?
