Troubleshooting

Symptom	What to check
The printer is missing	Check that the printer is on, the PC can reach the printer's local IPv4 network, and RAW TCP/9100 is enabled. Then use More → Find printer.
The printer appears but does not connect	Confirm the selected driver supports RAW printing and the device reports a stable identity. Check Local network and Routing for the selected adapter.
A job disappears without printing	Check Last connection error under Printer connection and check the printer's job log. Confirm delivery by checking the physical output.
The printer is slow to respond after sleep	Allow the bridge to retry. If printing fails, compare with the printer awake and note the last bridge error.

Use More → Diagnostics to save a report. Choose the option that removes network and queue identifiers before sharing. More → Report a bug previews a redacted report and opens a draft issue. Review the report before posting it to the public tracker.
