For the life of me...I can't figure out how to upgarde firmware on a "per printer" basis with Centerware Web.
You think it would be easy as select the printer and click upgrade firmware or some thing to the like.
I can add printers no problem, create groups and policies, but where can I upgrade individual printers for testing purposes? I am runnin Microsoft Server 2012R2.
