    Is there someone here, who has tried to drive this scanner ?
    Actually I didn’t find any ‘in depth’ documentation to understand what the signification of all customs capabilities. I can do reverse engineering on it of course, but if I can avoid this time consuming way it will be nicer.

    Actually with my code (tested on Kodak, Fujitsu and Panasonic scanners), the HP doesn’t take care of resolution, duplex and many capabilities set by my code. Instead it seems that it wants to load a specific setting ‘file’ previously saved, but I’m not sure, if the way to control it should be done by traditional capabilities setting, or by a brutal TW_CUSTOMDSDATA hack.

    What is not fun with this hack is to understand the sections significations and modify the rights ones without crashing the driver … 😉

    and I guess you’re not having any luck with just letting the driver’s ui build valid CustomDsData for you. shame there is typically so little documentation available from the vendors for their custom caps.

    Well that the way I use sometimes to track changes in the data structure returned by the GUI via CUSTOMDSDATA, but it’s time consumming (if this is the only way I do compare before and after settings changed).

    Also to explain, for other people reading this thread, I cannot let the GUI opened, for security reason, we don’t want the user to change the settings as they are fixed and validated elsewhere for each scanner.

    I don’t know why only Kodak gives all the documentation without having to ask for it … 🙄
