Android Question print to a printer connected via bluetooth

If your printer is compatible with Google Cloud Print (http://www.howtogeek.com/165778/eve...t-printing-from-your-android-phone-or-tablet/) then you can use this code to print: https://www.b4x.com/android/forum/threads/android-printing-framework.38796/page-2#post-247437

The other option is to connect to the printer with Serial library. For example: https://www.b4x.com/android/forum/threads/bluetooth-printing-via-spp.17692/

Hello Alfonso,
I have the same problem. I try with "BlueTooth Printing via SPP" POS sample but the printer only print sometimes, other times only make a CR without print and other send an error.
Do you solved the problem?
Do you speak spanish?

Jose Higinio

you have to follow the steps below as indicated in the post

- switch on the printer
- switch on BT on your device
- pair your device with the printer (pw on my printer is 1234, take a look at the manual)
- wait 'till it's paired and see the printer's name
- insert the first unique chars in the code (the MAC address is retrieved via the printers name)
- run the app and print
