Standard Epson drivers were installed:
kuzmin@bel02:~$ scanimage -L
device `epson2:net:10.0.2.82' is a Epson PID 1115 flatbed scanner
device `imagescan:esci:usb:/sys/devices/pci0000:00/0000:00:13.4/usb6/6-2/6-2:1.0' is a EPSON XP-342_343_345_Series

ImageScan sees only USB scanner and can do only Preview. The program offers to
scan in a file and does not create the file.

Xsane sees both scanners but its result is random points.

VueScan works OK, but includes in the image its wattermarks, demanding $20 for their disappering
in the home version.

SimpleScan tries to do something, but the result is wight field.

Can somebody comment the situation - is it hopelessly to do not pay?
