Problem: When trying to print from a BT4, the signature shows up as a line and won’t print from Android.
The signature shows up as a line and stops printing on android.
Cause: Older BT4 Firmware's are not compatible with Android Handhelds.
Resolution: There is no way to flash the firmware at this time so the only fix is to get a new printer.
