NAPS don't see sane scanner [WINDOWS 10]

[Yrij-Zhavoronkov]

Hi. I have a SANE server at 192.168.1.1 with Samsung SCX 4200 scanner.
SANE winDS see it, but not NAPS

[cyanfish]

NAPS2 doesn't support SANE on Windows. If you like you can set up an ESCL server with AirSane, though I'm also planning on building that into NAPS2 soon.

The error.log contains the same content that I have already provided.
Do I need to open a separate ticket for this bug to get a solution?

[cyanfish]

I can reproduce the problem testing myself with SaneWinDS, and it's definitely a crash coming from SaneWinDS, so it's a bug that needs to be fixed on their end.

It doesn't seem to be maintained but you could maybe also try WIASane.

And actually it does seem like AirSane is available on openwrt which is probably the best solution:

Readme of repo is broken at

I have 17.01 openwrt on ar71xx so:
docker run -i -t -u openwrt -w /home/openwrt/sdk -v $PWD:/work openwrtorg/sdk:17.01-ar71xx /bin/bash
but this docker image is not found, but exists yhnw/openwrt-sdk:17.01-ar71xx

run -i -t -u openwrt -w /home/openwrt/sdk -v $PWD:/work yhnw/openwrt-sdk:17.01-ar71xx /bin/bash
make package/airsaned/compile V=s -j8

Installing libpng via ./scripts/feeds install does not solve the problem, and libpng-dev too. This is why AirSane is not possible yet

I'm not sure if you're still trying to do this, but I've made some progress on SANEWinDS compatibility in #327.

[Yrij-Zhavoronkov]

It doesn't work anyway
