Pretty Printers for gdb

I have downloaded and installed the newest v14.3-rel1 -  AArch32 GNU/Linux target with hard float (arm-none-linux-gnueabihf)

While debugging, I noticed that there are no pretty printers stored in gdb.exe. When I enter the command “info pretty-printer”, I only get the output “Undefined info command: ”pretty-printer." Try “help info”." My expectations for the new version were that I would be able to reload libstdc++.so.6.0.33-gdb.py with Python 3 on Windows. 

Do you have any other ideas for a better representation of C++ classes, such as std::string or std::map?

Kind regards
