Re: [gscan2pdf-help] duplex scanning

Thank you for all the replies (they have only just come through to me,
sorry for multiple postings).
I did what was suggested in setting options but still only get single
sided scanning.
For Scan Options/Source there is "Flatbed" or "Automatic Document Feeder".
Below is the output from debug. I note that
"scanimage --device-name='epkowa:libusb:006:011' --mode='Binary'
--source='Automatic Document Feeder' --threshold='128' -x 210 -l 0 -y
297 --brightness='0' --speed='yes' --resolution='300' -t 0
--wait-for-button='no' --batch --progress"
does not include the command:
"--adf_mode Duplex"
which is an available option for the Epson scanner.
If I copy the scanimage line as generated by gscan2pdf in console and
add the "--adf_mode Duplex" to it I get duplex scanning.
Victor Warner.

Usage: scanimage [OPTION]...
Start image acquisition on a scanner device and write PNM 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 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), and %i (index number)
-b, --batch[=FORMAT] working in batch mode, FORMAT is `out%d.pnm' or
`out%d.tif' by default depending on --format
--batch-start=# page number to start naming files with
--batch-count=# how many pages to scan in batch mode
--batch-increment=# increase number in filename by an amount of #
--batch-double increment page number by two for 2sided originals
being scanned in a single sided scanner
--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
-n, --dont-scan only set options, don't actually scan
-T, --test test backend thoroughly
-h, --help display this help message and exit
-v, --verbose give even more status messages
-B, --buffer-size change default input buffersize
-V, --version print version information
