Used for Trouble: T-000045

1) Verify printer network settings

• Print printer network/status page
• Confirm IP address, subnet mask, and gateway
• Update settings if they no longer match the network

2) Check IP address changes

• Confirm printer IP did not change after network work
• Assign a static IP if required
• Update printer port on POS / CSC to match new IP

3) Verify VLAN and subnet placement

• Confirm printer is connected to correct VLAN
• Ensure POS / CSC systems can reach printer subnet
• Correct switch port VLAN assignment if incorrect

4) Check switch port security

• Verify port security or MAC filtering is not blocking printer
• Disable port security temporarily for testing
• Whitelist printer MAC address if required

5) Verify gateway and DNS settings

• Confirm printer gateway matches network design
• Correct DNS settings if printer requires name resolution
• Reboot printer after network changes

6) Clear cached printer routing

• Restart Print Spooler service
• Restart POS / CSC application services
• Reboot workstation if routing cache persists

7) Test connectivity

• Ping printer IP from POS / CSC
• Print Windows test page
• Send live test order

8) Escalation check

• If printer still fails:
• Capture network topology details
• Record printer IP, MAC, and switch port
• Escalat
