I have designed a Bank statement which is being printed out satisfactorily,however,the same print outs need to be put in an envelop by a machine called Kern Mailer.I understand that there are some conditions and some OMR marks that I need to specify on the planet press design but I don't know how to do it.The conditions are neeeded to enable the kern mailer identify how many statements belonging to a given customer should go to a specific Envelop.Please assist on how I should achieve this.
