Blue Bamboo P25 printer is a lightweight and portable thermal printer that provides low cost printing in mobile and wireless environments. It also has a good connectivity with Android device, makes printing from Android becomes very easy and fast. Blue Bamboo also provides a sample Android project to show how to build an application that supports printing using P25 printer over Bluetooth.

The source code itself is quite old so i made a slight modification with fresh UI and easy to read source code so developers can easily implement the codes into their projects. This sample code shows how to print text, image, barcode and receipt into P25 printer using Bluetooth connectivity.

The source code is available on Github repo, you can find it at the bottom of this post. Use Printer. For font types and text alignment, see FontDefine. Also call the PocketPos. FramePack byte typeFrame, byte[] srcBuff, int srcOffset, int srcLen to create frame data before sending to printer. See P25 development guide page for more information. See P25 development guide page 60 for more information.

All bytes data to be printed is sent to printer using sendData method from P25Connector class P25Connector. P25Connector is a wrapper class to handle bluetooth operation connect, disconnect, and bluetooth socket operation. Download source code from Github repo. Passionate web and mobile application developer. This is awesome! Is it possible to use it alongside a credit card reader application like square:. Slmt malam.

Hi have gotten a hand of your tutorial. Great one Loresius, From the source code when i printtext, reciept, barcode, or demo there extra strings printed before the actual print, do you know how they can be removed. Om Boleh di kirimin sorce code lenkap nggak?? Sebelumnya saya ucapkan terkma kasih atas artkel blognya mengenai printer bluebamboo yg sdh diupload di github.

Yang ingin saya tanyakan, apakah memungkinkan sdk tersebut digunakan untuk PHP web base system? Kasusnya begini: di tempat tersbut sudah memilikki aplikasi php web basejadi rencananya, aplikasi web base tersebut mau dibuka di tablet dan kemudian print menggunskan portable pos bluebamboo. Apakah memungkinkan? In your image printing, you said the image is px wide, but 0x24 is not 25 pixels rather 36 px. I think you want 0x Great post! Just bought BlueBamboo P10 bluetooth printer and thanks to this post I am able to print!

Last, I printed the image once and on subsquent printing wierd string are being printed out instead of the image. I have the printer but need to download the software on my phone. Is there a link to a download? I changed phones and need to download again. I use a square but use to use intuit as a merchant account.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Currently I am trying to deal with a strange Exception when opening a BluetoothSocket on my Nexus 7with Android 4. I have seen some related postings e. Also, as suggested in these threads, re-pairing does not help, and constantly trying to connect through a stupid loop also has no effect.

My Android 2. Here is the Snippet of the connection establishment. It is running in its own Thread, created within a Service. The code is failing at bluetoothSocket.

I am getting a java. IOException: read failed, socket might closed, read ret: Some metadata dump of the used socket resulted in the following information. These are exactly the same on Nexus 7 and my 2. Is there any chance, that I am missing something or might this be a bug in Android? I have finally found a workaround. Now, when I receive that exception, I instantiate a fallback BluetoothSocketsimilar to the source code below. As you can see, invoking the hidden method createRfcommSocket via reflections.

I have no clue why this method is hidden. The source code defines it as public though I have experienced a few issues still. Basically, this sometimes blocks and fails.

Sometimes I also get another Pairing request after connect even when the device is already bonded. The problem is with the socket. We need to use both socket attribsthe second one as a fallback. First, if you need to talk to a bluetooth 2.

However, this code seems to handle the problem of SDK version, and you can just replace the function device. The source code isn't mine, but comes from this website. I had the same symptoms as described here. I could connect once to a bluetooth printer but subsequent connects failed with "socket closed" no matter what I did.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I have to develop an App for Android tablets that demands printing files to a Bluetooth printer. Printing over Bluetooth is one of the most important features of my app. Unfortunately, there's not a lot of information about this subject so I'd like to ask for advice.

Doing a little research I've found the following alternatives:. As you mentioned, you can't print natively at this point in time so the alternate solutions you found are your options today. In my experience, it's best to use an API and not an external application.

Android – Send Print Command to Bluetooth Printer from Mobile

The biggest reason is you get total control over printer behavior. It's easy too if the API is built intelligently.

Using an external app is limiting because you can't customize your print outs the way you want to. The Star SDK I linked you to has a really nice sample app that lets you test and customize a lot of printer functions to see them in action. Each function is documented in the source code. The commands and their parameters are also available in the app itself as a quick on screen reference which is convenient. On top of all that, it's well documented. Star's a great company to work with because you can get a free demo printer of your choice to use for your development.

If you choose this way, you can send plain text to the printer along with commands. The API handles converting the data into what the printer can understand. The possibility of printing to BlueTooth printer depends highly on the model of printer you are trying to use. I even built a framework on top of that. The problem lies only in the fact you can not tell for sure which printer models will be used by end-users so some ultimate SDK will definitely be of great need.

For support head to StackOverflow rxandroidble. Read the official announcement at Polidea Blog. You can use singleton, scoped Dagger component or whatever else you want. The library does not handle managing the state of the BluetoothAdapter. See Javadoc of BluetoothAdapter. It is possible to show a native activity for turning the Bluetooth on by calling:. On Android it is not always trivial to determine if a particular BLE operation has a potential to succeed.

To be sure that the scan will work only when everything is ready you could use:. From BluetoothDevice. Auto connect concept may be misleading at first glance. With the autoconnect flag set to false the connection will end up with an error if a BLE device is not advertising when the RxBleDevice establishConnection method is called. Setting the auto connect flag to true allows you to wait until the BLE device becomes discoverable.

Be careful not to overuse the autoConnect flag. On the other side it has negative impact on the connection initialization speed.

Scanning window and interval is lowered as it is optimized for background use and depending on Bluetooth parameters it may and usually do take more time to establish the connection. If you want to observe changes in device connection state just subscribe like below. On subscription you will receive the most current state instantly. By default RxBleLog uses logcat to print the messages.

You can provide your own logger implementation to forward it to other logging libraries such as Timber.

BluetoothSocket; import android. ContentValues; import android. Intent; import android. Environment; import android.The Android platform includes support for the Bluetooth network stack. The Bluetooth network stack allows a device to wirelessly exchange data with other Bluetooth devices.

Android Things extends these APIs to enable apps to control the Bluetooth system settings, device pairing, and connection process. The Android Things Bluetooth APIs enable you to control the device class and supported profiles exposed by the local Bluetooth adapter. To configure the enabled Bluetooth profiles on the local device, use the BluetoothProfileManager.

Each BluetoothProfile must be enabled before a remote device can connect to it. Query the current set of enabled profiles with getEnabledProfiles and update them using one of the following methods: enableProfiles or disableProfiles :. See Finding Devices in the Android Bluetooth Guide for more details on discovering remote devices and determining if they are already bonded with the local device. If the remote device is already bonded, you can jump directly to connecting to a remote device.

The PairingParams provided to the callback defines the Bluetooth pairing variant required by the remote device. These represent different pairing security schemes, and your app is responsible for taking the appropriate action as documented for each variant. For pairing variants that require user input, complete the process by calling finishPairing.

Once you have successfully paired over Bluetooth, your app can connect to profiles and services on the remote device. The Android Things BluetoothConnectionManager enables apps to connect to additional profiles and services on remote devices.

Use the getConnectableProfiles method to report the available profiles on the remote device. To connect with a specific profile on a given BluetoothDevice :.

The ConnectionParams provided to the callback include additional details about the type of connection requested. Inspect those parameters in your code, and then determine whether to accept or reject the request with confirmOrDenyConnection :.
