I have the same question: How can I disable all printf() output easily without having to comment out each one of over 300 lines?

Another option can be to wrap the printf calls with a macro like the NRF_LOG_* macros.

#ifdef ENABLE_PRINTF
    #define DEBUG_PRINTF(...) printf(__VA_ARGS__)
#else
    #define DEBUG_PRINTF(...)
#endif

Then replace all the printf() calls with DEBUG_PRINTF() using search&replace in your code editor.
