Our printer (a Brother MFC-L8900CDW) supports scanning directly in network shares, provided over SMB. The SMB share is accessible for everyone in the verschwörhaus network. Sadly, the printer is not able to OCR the scanned stuff by itself - and this is the reason for the scanmagic script.
You need docker (for the ocr-container) and entr.
Pull the ocr container image: docker pull jbarlow83/ocrmypdf:latest
Configure scanmagic.sh by copying .env.sample to .env.
Add scanmagic as an systemd unit by copying scanmagic.service to /etc/systemctl/system/.
