Karl and Others: I went back over this log and discovered that the file epson.conf file had an incorrect entry . I changed the enty from "/dev/usb/scanner0" to "usb /dev/usb/scanner0" as I had been instructed. Thanks for your assistance and patience. Scanner seem to be working correctly and I have it working with gimp. One last question. Where do I get information with regards to linux drivers for my HP 970Cxi printer? I am not at all happy with the print quality.
Again thank you very much. John Dey Karl Heinz Kremer wrote: >On Sun, Oct 27, 2002 at 02:06:34PM -0500, John S.
