    Xerox copiers alter numbers

    Photocopiers made by Xerox are changing numbers on documents, a German computer scientist has discovered.
    David Kriesel found that copies he made of construction plans had altered room dimensions.

    Lossy compression leads to data loss. Hardly news.

    So long as it produces good copies of your arse, I don't see it as being a problem!

    Only happens when you muck with the settings (which have a big fat warning on them) and change them away from the defaults. The defaults for JBIG2 compression are set to lossless.
