Decision table
What the observation changes
ObservationWhat it meansNext action
Other devices can printPrinter engine/network is at least partly working.Focus on the affected computer's queue, driver and selected printer.
No device can reach/print and printer shows network issueNetwork/printer state is higher priority.Check printer network status/router path before reinstalling drivers.
Printer has an LCD errorOffline may be secondary to a printer fault.Resolve the exact printer message first.
Sequence
Work from reversible checks to escalation
- 01
Read printer LCD/status.
- 02
Check whether another device can print.
- 03
Confirm the computer is targeting the intended printer/queue.
- 04
Only reinstall software after network/device state is understood.
Likely areas
Keep these branches separate
Printer Wi-Fi/Ethernet pathWrong queue/IPOS print spooler/driverPrinter error state
Repair boundary
When to stop changing settings
Use Brother support if the printer cannot join the network or remains unavailable across clients after official network setup steps.
