 /**
+ * @page howtoPrinters Output Processing
+ *
+ * libyang provides a mechanism to generalize work with the outputs (and [inputs](@ref howtoParsers)) of
+ * the different types. The ::ly_out handler can be created providing necessary information connected with the specific
+ * output type and then used throughout the printers functions. The API allows to combine output from libyang (data or schema)
+ * printers and output directly provided by the caller (via ::ly_print() or ::ly_write()).
+ *
+ * Using a generic output handler avoids need to have a set of functions for each printer functionality and results in simpler API.
+ *
+ * The API allows to alter the target of the data behind the handler by another target (of the same type). Also reseting
+ * a seekable output is possible with ::ly_out_reset() to re-write the output.
+ *
+ * @note
+ * This mechanism was introduced in libyang 2.0. To simplify transition from libyang 1.0 to version 2.0 and also for
+ * some simple use case where using the output handler would be an overkill, there are some basic printer functions
+ * that do not require output handler. But remember, that functionality of these function can be limited in particular cases
+ * in contrast to the functions using output handlers.
