Added this to nixbld:

services.saned.enable = true;
services.saned.extraConfig = "192.168.1.0/24";

On the client machines, xsane fails with an obscure "Error during device I/O" upon startup. As seen in wireshark, the connection is established and there is a little bit of data exchanged.

The scanner otherwise works locally on nixbld using the scanimage command.

Adding this to the client machines does not help:

hardware.sane.enable = true;
hardware.sane.netConf = "192.168.1.1";

Does the scanner have a network interface? I know Brother devices that can upload scans via SFTP out of the box. That can be automated quite nicely.

This now works:

xsane "net:192.168.1.1:hpaio:/usb/HP_Color_LaserJet_MFP_M477fdw?serial=VNBKLBM2VN"

This now works: xsane "net:192.168.1.1:hpaio:/usb/HP_Color_LaserJet_MFP_M477fdw?serial=VNBKLBM2VN"
