Hi, After a failed firmware update, our HP Officejet K850 doesn't work anymore. The network Interface and the USB-Interface is dead. I tried also over the Parallel Interface (with an Network-Port-Server-Adapter) to reload/repair the firmware, but no success. The firmware-Update Programm AMR2009A.exe doesn't recognize the printer anymore.
Any ideas to bring the printer alive?
Thank you very much for your help
