/*! class RGPrintRequester
 *
 *  This class defines a print request:
 *  - either to print a file
 *  - either to get a printing command
 *
 *  In the command line, the file name is indicated by '%f' tag.
 *
 *  For a request returning a printing command, if '%f' tag is found, it
 *  is replaced by the file name, else the file name is added at the
 *  end of the command.
 *
 *  The type of request depends on the constructor choice.
 *  The options are kept in static variables of the class, so that
 *  they are memorized.
