+    This block prints bursts to output. By default the whole burst including tail bits, stealing bits and training sequence is printed.
+
+    If "Prepend Frame Number" is enabled, then the framenumber is prepended to each burst.
+
+    If "Prepend Frame Count" is enabled, then the frame count for A5 is prependend to each burst.
+
+    If "Print payload only" is enabled, then only the two data blocks of a burst are printed, tail bits, stealing bits and training sequence are omitted.
+
+    If "Ignore dummy bursts" is enabled, then the burst printer will not print dummy bursts (see GSM 05.02)
+
+    Enabling first three options (or all four options) results in an output that is similar to the output of airprobe, i.e. the format is "frame_nr frame_count: databits"
