Printer permissions on Android
Symptom: on an Android phone or tablet the scan finds nothing, a Bluetooth printer never appears in the chooser, or a printer at a known address times out.
Why it happens
Android gates these separately, and a denial is silent — a blocked connection times out exactly like a printer that's switched off.
- Nearby devices covers finding and connecting to Bluetooth printers.
- Local network access is required on recent Android versions before an app can reach anything on your Wi-Fi.
Turn the permissions on
- Open Android Settings → Apps → WCPOS → Permissions.
- Allow Nearby devices.
- If Local network is listed, allow that too. Older Android versions don't have it.
- Close the app and open it again, then scan.
Bluetooth printers
On Android, Epson and Star printers connect through their manufacturer's own software, and they must be paired in Android first — Settings → Connected devices → Pair new device — before they show up in the app. Small Bluetooth Low Energy printers are picked in the app's own chooser instead; don't pair those in Android. See Pairing a Bluetooth receipt printer.
Wi-Fi printers
Check the tablet is on the shop's Wi-Fi rather than mobile data or a guest network. If the scan comes back empty but you know the printer's address, use Enter an IP address — it checks the one address directly and doesn't depend on discovery.
