Upgrading the devices progressively 
If another PC is available (recommended by HP) 
•  Install the new Command Center Server and Client version on a second PC (“PC2”). 
•  (Step needed only if you are upgrading to model 4210) Remove the devices from PrintOS as product numbers will 
change. You need to log in to your (customer) PrintOS account with a web browser (www.printos.com) and remove the 
device by clicking the trash ( ) icon. 
•  When upgrading a device to firmware version TATDAG_14_18_05.X or later, remove the device from the old Command 
Center on PC1 and add the device to the new Command Center on PC2. 
•  Once all devices have been migrated to the new firmware version, remove the old Command Center version from PC1. 
•  (Optional) If you want to keep the PC1 as the Server PC for Command Center, uninstall Command Center on PC2 and 
then install the new Command Center version on PC1, then add all the devices back in again (all of them MUST have 
been migrated to the new firmware version). 
If only one PC is available 
•  Uninstall the older Command Center Server and Clients and reboot your PC. 
•  Upgrade some of the devices to firmware version TATDAG_14_18_05.X or later. 
•  Install the new Command Center Server and Client version. 
•  Add all the devices to Command Center (with both older and new firmware versions). 
•  When a device is upgraded to a new firmware version, remove it from Command Center, upgrade its firmware and then 
add it back to Command Center again (credentials will need to be refreshed in order for the information to be sent 
correctly). If this is not done, the device won’t be connected correctly to the HP Cloud and printing/loading powder will 
not work. 
Important: Avoid adding TATDAG_14_18_05-firmware devices to HP SmartStream Command Center versions previous to 
1.6 as these devices won’t be correctly connected to the HP Cloud and printing/loading powder will fail. Remember to 
remove the device from the Command Center and add it again after upgrading the device to firmware version 
TATDAG_14_18_05.X, as otherwise, it won’t be correctly connected to the HP Cloud and printing/loading powder will fail.
