Other ways to discover Printers in a large network?

[Kumar19]

Are there other ways to Discover printers other than SNMP?

Yes, while SNMP is the most common protocol used by ServiceNow Discovery to identify and classify network printers, there are other options depending on your environment and integration needs:

1. WMI (Windows Management Instrumentation):
If printers are connected to Windows servers or workstations, you can use WMI to gather printer data as part of a Windows discovery pattern.

2. LDAP / Active Directory:
Printers published in Active Directory can potentially be discovered via LDAP queries, especially if you're using ServiceNow MID Servers integrated with AD.

3. IP Range Scanning with Port Probes:
You can configure custom Discovery Patterns or use horizontal discovery to scan IP ranges and probe for known printer ports (e.g., 9100, 515, 631, or 80 for web interfaces).

4. mDNS / Bonjour (in limited or custom scenarios):
Although not natively supported by ServiceNow Discovery, some environments use mDNS to register printers, and you could theoretically extend MID Server capabilities to integrate this through scripting or custom probes.

5. CMDB Integration or Import Sets:
If another system (like a print server or asset management tool) maintains printer data, you can import that into the CMDB using IntegrationHub, Import Sets, or API-based integrations.

In short, while SNMP remains the primary protocol for printer discovery in ServiceNow Discovery, other options exist depending on how printers are deployed and what other systems you're working with.
