Preview work by final file not saved
I'm trying to get an Epson-V39 to work on Ubuntu 18.04LTS. Preview works, the sanne sound like doing something but no file is written on disk (independently of chosen output format)
Note as it is V39 I had to retrieve esci-gt-s650 plugin from Epson website install libdrv-esci.la and apply following link to get utsushi to accept starting and make a image previous. Nevertheless I did not find how to go further.
vero@Fulup-ThinkPad-X250:/opt/imagescan/libexec/utsushi$ ls -l
total 10084
lrwxrwxrwx 1 vero vero 16 oct. 19 14:05 esci-gt-s650 -> esci-interpreter
Note: I have the same behavior with pre-build binary version, gitlab master code or last sources taken from Epson website.
