Product: HP DesignJet Z9+dr 44-in PostScript Printer with V-Trimmer

Good day - our Network Security team reports "TLS Protocol Session Renegotiation Security Vulnerability" has been found on one of our devices:
HP DesignJet Z9+dr 44-in PostScript Printer with V-Trimmer

I've tried disabling TLS 1.0 and 1.1 (leaving only 1.2 checked) and updating to SNMPv3, but they report the vulnerability still exists. Current firmware version is "JGR9_09_23_48.1".

Can anyone provide some advice on how to remedy this issue? We don't have any issues connecting or printing to the device, but Network Security will keep hounding us until this is fixed.

Thanks in advance!

Unless I am mistaken, your product ID is X9D24A

 

Parts list is here

 

All software is here

 

The latest firmware is 9.26.15

I have no idea if that firmware will fix the problem.  My suggestion is to disable the Wi-Fi and just use hardwired ethernet connection.
