Looking at the Agilent manual, it appears that you need to use the printer in parallel mode (SWDIP 1, switch 1 on), which is the default config. In this mode, many of the settings for baud rate, etc., don't apply. The 'scope is also printing in graphics mode, so text and column settings are ignored. Have you tried a different parallel printer cable? I have had problems with cables that are "good" not working with a particular device/printer combination. Sorry that you are having such troubles. I use my Seiko in serial mode, so haven't had to configure it with a parallel output device myself.
