Thanks to all. So far I was able to reproduce this scenario which works.

def myPrint001(opts)
  formater = 'MyPrint2' + opts[:format]
  o = Class.new(Object.const_get(formater)) do
    def printHDR
      image 'image.jpg' 20, 1
      print 'some header text' 1,5
      ...
    end
    def doJob
      print 'some text' 1,5
    end
  end.new
  o.doJob
end
But it's kinda ugly.


I do prefare Thomas aproach with MyPrintFactory if there was a way to 
avoid to preceide every keyword with 'printer.' statement.

printer = MyPrintFactory.getPrinter :format => 'html'
printer.doJob

In my last OO language I was using (Alaska XBase++ if known to anybody 
;-) I actualy had precompile directive which replaced print with 
printer.print before compilation.


More ideas anybody.
