HP printers are comonly detected in financial institution audits due to a vulnerable SSL version in use.  Many older models contain multiple vulnerabilities that cannot be fixed with firmware upgrades because the older printers are no longer supported.
 
Customers can use the HP WebJet Admin software to manage these printers through SNMP and disable the web server completely.  However make sure the SNMP community strings have been changed from the default "public" and "private".
