Thanks Johannes, I'll see what information I can get through the HPLIP mailing list. I saw the listing on the support page that claims that the 4100 doesn't have network support, and I am confused what that means. I can ping the printer on the network. I can print to it over the network. I've been doing that for months now.
Where does "scanimage -L" get its information from? Does reply indicate that it is connecting to the printer, or just that the driver is installed? I guess it must be the latter since I get the same response with the printer turned off. -steve On Wednesday 30 May 2007, sane-devel-request at lists.alioth.debian.org wrote: > Hello, > > On May 29 10:29 Steven Legowik wrote (shortened): > > I am trying to access the scanning function of a network attache HP > > LaserJet 4100MFP, but I keep getting "Error during device I/O" from > > xsane. > > > > Using scanimage I get the following: > > > > [legowik at tahiti ~/proj]$ scanimage -L > > device `hpaio:/net/HP_LaserJet_4100_MFP?ip=192.168.1.152' is a > > Hewlett-Packard HP_LaserJet_4100_MFP all-in-one > > > > [legowik at tahiti ~/proj]$ > > scanimage -d "hpaio:/net/HP_LaserJet_4100_MFP?ip=192.168.1.152" > > scanimage: open of device > > hpaio:/net/HP_LaserJet_4100_MFP?ip=192.168.1.152 failed: Error during > > device I/O > > The hpaio driver is not part of the SANE software but a so called > "external backend", which comes directly from HP, see > http://hplip.sourceforge.net/ > > See > http://hplip.sourceforge.net/troubleshooting/network.html > > But > http://hplip.sourceforge.net/supported_devices/mono_laser_mfp.html > indicates that there is "No" network support for the LaserJet 4100mfp > so that you may have to connect it only directly via USB. > > For details you may ask on the HPLIP mailing list: > http://hplip.sourceforge.net/mailing_lists.html > > > Kind Regards > Johannes Meixner
