I’ve been asked to identify all network-connected printers in our organisation. I’ve used HP Web JetAdmin and Xerox Centreware successfully elsewhere in the past but I need to use Greenbone here because it already has access to all our VPNs and through all our firewalls. Another solution is unlikely to be given this access.
Although Greenbone has detected some printers (mainly HP), I know it has missed others. I know it does not scan devices if port 9100 is detected to avoid paper wastage but even if I switch off this option, printers are not found.
Are there any tests I can use within Greenbone to interrogate printers and get their model number, firmware version etc? I have enabled the snmp tests without success. Even getting it to produce a list of ip addresses listening on port 9100 would be useful.
