Your question is ... confusing.

You have:

   a = [ 65, 32, 66 ]

When you print it, what do you want to see?

  "65, 32, 66" # use puts a.join(", ")
  "A B" # use puts a.map { |e| e.chr }.join
  "65 32 66" # use puts a.join(" ")
  "0x41, 0x20, 0x42" # use puts a.map { |e| "0x%02x" % e }.join

So, what are you looking for?
