Dear Sir,
     Many thanks for giving us a chance to demonstrate our new laser printer for you last week.
     I was pleased that you saw quickly how to operate this laser printer to meet your own requirement. I have taken the liberty of preparing a printing format based on the copy you gave me and I would like to reemphasize that part of our support service includes assisting your people to develop your own printing formats for your major repetitive needs. Please let me know if there is any more information you need to come to a decision. Looking forward to being of service to you.
