There are also some third party printing packages, that could overlay items like your logo.We have used Reform and Flexform. Some printers even have the cability today to add a overlay to printouts printed to a given tray. I ran into this last week at a client that had a copier installed and setup as a printer on the network. I was able to print a graphics image to a pcl file, then upload it to the printer. When ever they print to tray 3 the printer automatically adds the PCL into the print stream. Was a nice feature that they were not aware of getting in advance.
Some print drivers on cheap printers support something close with the watermark feature. You can setup the print driver muliple time for the same printer with different default settings.
