Hello,
using Ubuntu 18.04 with scanimage (sane-backends) 1.0.31-179-ge4ef0548b;
backend version 1.0.31 (installed from ppa), I get:
scanimage -L
device `epson2:net:192.168.2.101' is a Epson PID 08B9 flatbed scanner
device `epkowa:net:192.168.2.101:1865' is a Epson WF-7610/7620 Series
flatbed scanner
device `airscan:e2:Canon MF745C/746C' is a eSCL Canon MF745C/746C eSCL
network scanner
device `airscan:w3:EPSON WF-7620 Series' is a WSD EPSON WF-7620 Series
WSD network scanner
(notice "airscan:e2:..." Yet
scanimage --help -d 'airscan:e2:Canon MF745C/746C'
Usage: scanimage [OPTION]...
Start image acquisition on a scanner device and write image data to
standard output.
Parameters are separated by a blank from single-character options (e.g.
-d epson) and by a "=" from multi-character options (e.g.
--device-name=epson).
-d, --device-name=DEVICE use a given scanner device (e.g. hp:/dev/scanner)
--format=pnm|tiff|png|jpeg file format of output file
-i, --icc-profile=PROFILE include this ICC profile into TIFF file
-L, --list-devices show available scanner devices
-f, --formatted-device-list=FORMAT similar to -L, but the FORMAT of the
output
can be specified: %d (device name), %v (vendor),
%m (model), %t (type), %i (index number), and
%n (newline)
-b, --batch[=FORMAT] working in batch mode, FORMAT is `out%d.pnm'
`out%d.tif'
`out%d.png' or `out%d.jpg' by default
depending on --format
This option is incompatible with
--output-file. --batch-start=# page number to start naming
files with
--batch-count=# how many pages to scan in batch mode
--batch-increment=# increase page number in filename by #
--batch-double increment page number by two, same as
--batch-increment=2
--batch-print print image filenames to stdout
--batch-prompt ask for pressing a key before scanning a page
--accept-md5-only only accept authorization requests using md5
-p, --progress print progress messages
-o, --output-file=PATH save output to the given file instead of stdout.
This option is incompatible with --batch.
-n, --dont-scan only set options, don't actually scan
-T, --test test backend thoroughly
-A, --all-options list all available backend options
-h, --help display this help message and exit
-v, --verbose give even more status messages
-B, --buffer-size=# change input buffer size (in kB, default 32)
-V, --version print version information
Output format is not set, using pnm as a default.
scanimage: open of device airscan:e2:Canon MF745C/746C failed: Invalid
argument
Type ``scanimage --help -d DEVICE'' to get list of all options for DEVICE.
List of available devices:
epson2:net:192.168.2.101 epkowa:net:192.168.2.101:1865
airscan:e0:Canon MF745C/746C airscan:w3:EPSON WF-7620 Series
notice "airscan:e0:..."
Addressing the scanner as "airscan:e0:..." works great. Not a big
problem, I just find it kind of funny.
