I have a few more specifics on this that might be of some value to developers. Would be curious to know if any of this holds true for running under Linux. I am able to utilize xscanimage without any core dumps. I can preview in full color. Unfortunately it's nearly unusable due to it being nearly 2 inches off target in the preview scan. In other words, whatever area I hi-lite to do a full scan, I get an area about 2 inches below that. XSane I've managed to work around to sort of usable. If I do a half-tone preview I can then do a full scan in color. Unlike xscanimage, the selected area appears to be right on target. It's really hokey, but it's workable I suppose. Lastly, of course, the core dumps in XSane if one attempts to do a full color or gray scale preview. Are all these items specific to FreeBSD alone for this scanner? Should I be passing this information along to the uscanner developers? Is there anything else I should be looking to collect in the way of info? > Michael Collette wrote: > > Recently purchased this Hp 6300C to connect via USB to my laptop running > > FreeBSD.
