# Android Permissions **Symptom:** on an Android phone or tablet, **Add printer** says **No printer found**, or your Bluetooth printer is missing from the results. If WCPOS isn't allowed to use Bluetooth, it can't find Bluetooth printers. Check it first. A Wi-Fi printer needs no permission on any Android version: go straight to [Wi-Fi printers](#wi-fi-printers). ## Let WCPOS reach your printer[​](#allow-nearby-devices "Link direto para Let WCPOS reach your printer") 1. For a Bluetooth printer, check Bluetooth is on in Android's quick settings. 2. Find your Android version: open Android **Settings → About phone → Android version**. 3. Open Android **Settings → Apps → WCPOS → Permissions**. 4. Allow the permission for your version: * **Android 11 and older:** there is no Nearby devices permission. Tap **Location** and allow it. These versions need Location to find Bluetooth printers. * **Android 12 and newer:** tap **Nearby devices** and choose **Allow**. This lets WCPOS find Bluetooth printers and connect to them. 5. Go back to WCPOS and tap **Scan again** on the **Add printer** screen. When your printer appears, tap **Print a test page** below its card. If the page prints and the ruler across it looks right, answer **Yes, and it looks right**: the printer is saved and the fix worked. The full walkthrough is in [Add a printer](/pt-BR/hardware/receipt-printers.md#adding-a-printer). Menu names in Android's own Settings vary a little between phone makers, but every Android phone has a **Permissions** page for each app. ## Bluetooth printers[​](#bluetooth-printers "Link direto para Bluetooth printers") Once the permission is allowed, WCPOS looks for Bluetooth printers. Whether it finds yours also depends on the kind of Bluetooth the printer uses: * **Bluetooth Low Energy printers** show up in the scan by themselves. They don't need pairing in Android. * **Classic Bluetooth printers**, which include many low-cost 58 mm printers, only show up once Android has paired them. On the **No printer found** screen, tap **Open Bluetooth settings**, pair the printer there, then come back and tap **Scan again**. Not sure which kind you have, or the printer won't pair? [Pairing a Bluetooth receipt printer](/pt-BR/hardware/receipt-printers/bluetooth-printers.md#classic-or-low-energy) explains how to tell, and how to put the printer into pairing mode. ## Wi-Fi printers[​](#wi-fi-printers "Link direto para Wi-Fi printers") Check the phone or tablet is on the shop's Wi-Fi, the same network as the printer, and not on mobile data or a guest network. If the scan still comes back empty but you know the printer's address, tap **Enter an IP address**. It skips the scan and checks that one address directly. The address is printed on the printer's status sheet. See [Finding your printer's network address](/pt-BR/hardware/receipt-printers/network-printers.md). ## If something goes wrong[​](#goes-wrong "Link direto para If something goes wrong") ### Discovery failed[​](#discovery-failed "Link direto para Discovery failed") A red line under **No printer found** says printer discovery failed, for example "Bluetooth is off or not allowed for this app." Bluetooth is off on the phone, or WCPOS isn't allowed to use it. Turn Bluetooth on and [allow the permission for your Android version](#allow-nearby-devices), then tap **Scan again**. ### Printing not allowed[​](#printing-not-allowed "Link direto para Printing not allowed") After a test print, **Nothing printed** says "The app was not allowed to reach the printer. Allow it in your system settings, then try again." Android refused WCPOS when it tried to print. [Allow the permission for your Android version](#allow-nearby-devices), then tap **Try again**. ### Printer needs pairing[​](#printer-needs-pairing "Link direto para Printer needs pairing") After a test print, **Nothing printed** says "Pair the printer in this phone's Bluetooth settings, then scan again." The printer uses Classic Bluetooth and Android no longer has it paired. Tap **Open Bluetooth settings** below the message, pair it, then tap **Start over** to scan again. ### Allowed, but the printer is still missing[​](#still-missing "Link direto para Allowed, but the printer is still missing") Nearby devices (or Location on Android 11 and older) is allowed and the printer still isn't found. Turn the printer off and on, then tap **Scan again**. If it is still missing: * **Bluetooth printer:** see [Pairing a Bluetooth receipt printer](/pt-BR/hardware/receipt-printers/bluetooth-printers.md) for the other causes. * **Wi-Fi printer:** check the network and try the printer's address, as in [Wi-Fi printers](#wi-fi-printers). ### Still stuck[​](#still-stuck "Link direto para Still stuck") If the printer never shows up, there is no test print to report on: contact us below and tell us your Android version and the printer's make and model. If the printer shows up but won't print, tap **Copy setup report** on the **Nothing printed** screen. That screen opens by itself when a test print fails, or when you answer **Nothing came out** after a test print. On Android, Copy setup report opens the share menu: send the report to us by email, or copy it into your message. It lists your app version, the printer, what the app tried and what the printer answered.
