If i remember correctly my bjnp support was added in sane 1.0.19 (may have been 1.0.20). If you really need it, just rebuild a recent Fedora sane. Printing should work if you use the cups-bjnp package from EPEL if you can find a working printer driver. If needed, I can provide you a rebuilt sane-backends(-libs) (ok, done, see www.fazant.net/sane). I quickly hacked the Fedora spec file (removed the dep on i4l-devel and changed the version-ed dependency on udev to an unversioned one).It works on my MP980, the replacement for the MP970 which I used to develop the network support for Canon scanners. I am not sure that the hack for udev is correct, but you don't need udev for the Canon network support. Don't complain if you have problems with USB or other scanners though ;-) Louis
