PCL Identification

Does anyone know how to definitively determine whether or not a file is of
type PCL5, by means of parsing the PDL stream with a language such as C++?

Thanks,

The only definitive way would be to run it through a PCL5 interpreter.

Most software that does that is rather more simpleminded. If you
expect data to be either PJL, PS, PCL, Epson ESC or plain text, it's
not too hard to guess which with a few lines of checks.
