error: 'int printResponseCb' redeclared as different kind of symbol

Sounds like a problem in your sketch, maybe you put a function definition above the Printers.h include and forgot some kind of bracket somewhere? Looking at the error message, you're using ZdpScan.ino, but the line numbers are off, so I assume you've modified the sketch.

Also, just dumping error messages in an issue without further explanation or comments is not very polite IMHO. I'm not sure what the policy for this repository is, but often issues are primarily used for bugs in the library, not for getting help with debugging your own code. Asking for help might very well be ok, but you're not quite doing that either.

Anyway, to be able to help, you should probably also post the ZdpScan.ino file you are using. If you do, be sure to use triple backtick code blocks around your code, which makes it easier to read (you could edit your first post and add them around the error output too).
