bummer, it seems that the device’s current driver does not correctly support Dat_Layout/Msg_Set. I would probably still try setting the layout with different values unless I had the option of using another scanner or even better (unless I could use a different scanner) I would check if there were another driver for the model. I have had more success with the hp drivers that have ‘minimal’ or ‘commercial’ in the name – the hp scanners that I have worked with seem to consistantly install a driver that I don’t like by default but then have another driver on the CD. Check the Cd that came with the scanner (or Hp’s site) for another driver, hopfully one that reads ‘Hp 1220 Minimal twain driver’ or ‘Hp 1220 Commercial Twain drvier’ as those drivers typically offer more control of the device. If you find such a driver rerun twister and post the report otherwise play with Dat_Layout/Msg_Set but expect some inconsistant results as it seems that the driver may not quite support the twain capabilites as they are described in the specification.
