SAMSUNG M2070W Activer Scanner linux Ubuntu 20.04

L'installation par défaut du pilote ne fonctionne pas. Pour corriger il faut créer des liens symboliques manuellement après l'installation.

Pour faire découvrir le scanner en réseau utiliser la commande :

smfpnetdiscovery

qui devrait retourner quelque chose comme

Network socket://192.168.0.105 "Samsung M2070 Series" "Samsung M2070 Series on 192.168.0.105" "MFG:Samsung;CMD:SPL,URF,FWV,PIC,EXT,SPDS;MDL:M2070 Series;CLS:PRINTER;CID:SA_SPLV3_BW;MODE:SCN,SPL3,R000105,SCP;"
network ipp://192.168.0.105 "Samsung M2070 Series" "Samsung M2070 Series on 192.168.0.105" "MFG:Samsung;CMD:SPL,URF,FWV,PIC,EXT,SPDS;MDL:M2070 Series;CLS:PRINTER;CID:SA_SPLV3_BW;MODE:SCN,SPL3,R000105,SCP;"


installer le pilote

puis création des liens symboliques

ajouter "smfp" dans /etc/sane.d/dll.conf

tous les autres backends peuvent être commentés

chmod 644 smfp-samsung.conf

ajouter

<model vendor="samsung" id="m2070w" modelstring="M2070 Series"/>

dans smfp.samsung.conf
