Additional context

scanimage -L
device `epson2:libusb:001:004' is a Epson PID 0851 flatbed scanner

Most likely this is an old version of scanimage because it's running buster. I will attempt to look into this when I get a chance - I'm always keen to support older systems. But it's also likely resolved if you upgrade to bullseye.

Hi, I have the same problem. I isolated it to running sudo /usr/bin/scanimage -d 'hpaio:/usb/...' --mode 'Color' --source 'Flatbed' --resolution 300 -l 0 -t 0 -x 210 -y 297 --format 'tiff' --brightness 1000 --contrast 1000 -o data/temp/~tmp-scan-0-0001.tif in terminal, which ends with error:

/usr/bin/scanimage: invalid option -- 'o'

I have older Raspberry OS on this Raspberry Pi. It works well on the second Raspberry Pi with Debian 11. So, could you look at it and possibly add support for older OSes? I though this problem started with the last update.

[sbs20]

Yeah, I'm working on it. It was this PR

The thing is, that PR fixes other issues... I'm working on it.

Please use an older release for now.

[ceskyDJ]

Thanks for your work. Don't hurry up, it's not too critical.

[sbs20]

For reference, it was added in 1.0.28 which was after the version used by buster.

This issue is itself a regression because of #417 but only for older versions of scanimage

[sbs20]

Ok. It's not released yet, but the code is on master - would be great if you could give it a go on both buster and debian. I've tested as much as I can but the real world is often different.

[ceskyDJ]

Ok, I'll try it and let you know.

[ceskyDJ]

@sbs20, I tried to run code from the master branch (using similar steps as in https://github.com/sbs20/scanservjs/blob/master/docs/install.md#manual-download-and-install) but I failed. Installation of official release "works" (with the error of this thread). Could you send me any hint, please?

[ceskyDJ]

Ok, I tried more and finally I got it. On older RaspberryPi OS it works well (the place, where it doesn't work before). The second Raspberry Pi I have is in a different place, so I could test the pre-release after 27th December, if it is ok.

[sbs20]

Oh nice one! Yeah, no hurry 🎅

I have the same problem. Waiting for the new release.

Could you try pre-release version in master branch?

Thanks for you quick reply.

I tried this: I downloaded the master branch and unzipped it, then

cd /home/pi/Downloads/scanservjs-master/packages
sudo chmod -R 777 server
sudo ./server/installer.sh -i
sudo journalctl -e -u scanservjs

the log shows

In var/www/scanservjs, there is no server folder, but only the scr folder. I know I did something wrong, but cannot figure out how to do it.

[ceskyDJ]

Oh, I'm so sorry... I completely forgot about this. The newest release works ok on newer Raspberry Pi with Debian 11, so it should be ok.

Ha, don't worry - and certainly no need to apologise!
