Times loop isn't looping

I'm creating a little script that will send 10 jobs to a printer. I'm trying to loop one of my methods using a times loop except when I run the program, it won't loop, it just send one job..

Example:

[<user>@<server> ruby]$ ruby clean_printer laser32
request id is laser32-1038115 (1 file(s))
[<user>@<server> ruby]$

Am I doing something wrong to where this won't loop..?

Source:

#!/usr/local/bin/ruby

class CleanPrinter

  attr_accessor :printer

  def initialize(printer)
    @printer = printer
  end

  def create_jobs
    exec("lp -d #{@printer} test.txt")
  end

  def loop
    10.times do
      create_jobs
    end
  end
end

test = CleanPrinter.new(ARGV[0])
test.loop

Yes it's a class, yes I will take it out of the class.

Note that exec() actually replaces the current process image, thereby effectively exiting your program on the first iteration. You might want to switch to using system() instead.
