Print server queue works but direct IP printing fails

Scenario

Users can print through the server queue, but direct IP printing to the same device fails from certain workstations.

Recommended Resolution Path

1. Compare protocol and port settings between the working server queue and the failing direct queue.
2. Inspect local firewall rules and SNMP status settings on the client queue.
3. Check whether the printer requires raw 9100, LPR, or a secured protocol.
4. Document the supported print path so ad hoc direct queues do not keep proliferating.

Technician Notes

Document what changed, what confirmed the fix, and whether the issue points to a broader standards gap worth addressing for the client.
