Yes- the --ald option should work with the ix500. The only problem will be duplex mode. The backend has to buffer the back side image during the scanning process. It will allocate a buffer large enough to hold the image size you requested, even if --ald will prevent that much data from being received. Since Linux allows overcommit by default, this might not be a problem in your case. allan -- "well, I stand up next to a mountain- and I chop it down with the edge of my hand" -- sane-devel mailing list: sane-devel@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/sane-devel Unsubscribe: Send mail with subject "unsubscribe your_password" to sane-devel-requ...@lists.alioth.debian.org
