More than one method matched your request. You can refine
your search by asking for information on one of:

     CGI#print, IO#print, IO#printf, Kernel#print, Kernel#printf,
     Kernel#sprintf, StringIO#print, StringIO#printf,
     Zlib::GzipWriter#print, Zlib::GzipWriter#printf

明示的に指定しないといけないのですね。

>ri Kernel#print
----------------------------------------------------------- Kernel#print
     print(obj, ...)    => nil
------------------------------------------------------------------------
     Prints each object in turn to +$stdout+. If the output field
     separator (+$,+) is not +nil+, its contents will appear between
     each field. If the output record separator (+$\+) is not +nil+, it
     will be appended to the output. If no arguments are given, prints
     +$_+. Objects that aren't strings will be converted by calling
     their +to_s+ method.

        print "cat", [1,2,3], 99, "\n"
        $, = ", "
        $\ = "\n"
        print "cat", [1,2,3], 99

     _produces:_

        cat12399
        cat, 1, 2, 3, 99
