I tried this in XSane but couldn't figure out how to get it to scan two pages with me clicking something when the second page is ready. It scanned first page, then scanned the second without giving me a chance to flip it over. So, XSane didn't work this time. Maybe I'm doing something wrong. So, convert was my next test. I scanned in both sides, cd'd to the directory where the files were and issued the command Grant provided. At first, I got the security error. I dug around a bit and figured out how to tell it to ignore that and tried again. YEPPIE!!! It worked. I opened it in a pdf viewer and it was two pages. I don't need to print this one but I can send it to a friend since it is her mail, sort of. If I needed to print it, it should print duplex just fine. It's command line but it works. It's awesome. Still open to suggestions but for now, I got something working. It's easier than using LOo for sure. Dale :-) :-)
