+============================================================
+The Print API functions are helpful for printing Unified Runtime API objects'
+values as human-readable strings using C interface. Those functions are complimentary
+to the set of operators in the Print API C++ header (ur_print.hpp).
+
+Each function is named in the same style based on the Unified Runtime object name
+to be printed. See examples:
+
+To print the :any:`${x}_function_t` object's value, call:
+    :ref:`${x}PrintFunction`
+
+To print the :any:`${x}_kernel_arg_local_properties_t` object's value, call:
+    :ref:`${x}PrintKernelArgLocalProperties`
+
+There is also one 'extras' function in this API, which can be used for printing
+all values of given function's parameters - :any:`${x}PrintFunctionParams`.
+
+See :ref:`core/api:Print Functions` for the description of common parameters of Print API functions.

+## Generate Print API documentation
+Print Functions
+------------------------------------------------------------------------------
+All functions output strings to print to the :any:`buffer` of a given
+size :any:`buff_size`. The outputted string's size is retrieved
+with the :any:`out_size` parameter.
+It is required for :any:`buff_size` to be less than :any:`out_size` in order
+to write the output string to the :any:`buffer`. Otherwise, :any:`buffer`
+will not be modified.
