Our HP DesignJet Z6200 60in banner printer firmware will not update. It is currently on KHN_03_00_04.50 and i am trying to update to the latest which is KHN_02_00_05.2.
I get an "Update:failed Try again." message each time. i tried different browsers and the printer is not trying to print a job while doing the update.
