What is the firmware version? I do not see any new versions on the HP website since 2013. What is the printer model number - something like N911a? You can find both of these from the front panel as follows:
1. From the Control panel, press Help (?) button, select Printer Information [where the model number can be found]
2. Use the down arrow button to scroll to the 2nd screen
3. The current firmware revision will appear on the screen
