hi hak0983,
Try rearranging you grammar to look something like this it might help (untested). If you need some more grammar for reference there is a post with compound statements here.

my $grammar = q{ 

# --- Tokens ---

    EOF             : /^\Z/

    IDENTIFIER      : /[A-Za-z]\w*/
    QUOTE        : '\''

# --- Rules ---


parse           : stmt(s?) EOF
            { $item[1] }
        
stmt            : print ';'        { $item[1] }
                 | <error>
print           : 'print' QUOTE IDENTIFIER QUOTE { $item[2] }
}

This should also allow you to have multiple print statements per line as long as they are separated by a ';'.
