Probably; see the following RFCs for a definition of IPP and its message format; you need to POST a chunk of data with the application/ipp content type, and then parse the response that comes back (again, as application/ipp data):

The bundled CGI programs do not provide a public API, so they should not be used for anything.

Not possible with the current CGI programs.

You might look at writing your own CGI program to run on the print server then; it can convert your client-side requests to real IPP requests and convert the IPP responses to the json data.
