[sane-devel] Duplex Scanning using XSane

Discussion:

Hello All,

I am new to SANE back-end development.
I need help on how to do a Duplex Scanning from Xsane as a user.
Also how the back-end should collaborate with the Xsane for Duplex Scanning.

Can anybody refer to any document which can guide me.

Thanks & Regards,

Your backend should expose an option which enables duplex. Some
backends use a boolean for this, my backends have a string option
called 'source' which will list the available sources for images: 'ADF
Front', 'ADF Back', 'ADF Duplex', 'Flatbed', etc.

Xsane is not really designed for multipage document scanning. It will
work if you set the page counter equal to, or higher than the number
of images you will get from your batch. This requires counting or
guessing, and is less than ideal.

A better frontend for multipage scanning is gscan2pdf. You might wish to try it.

Thanks Allan.
I am currently evaluating gscan2pdf.
By the way we could do a duplex scan via Xsane using a Network Scanner,
but for USB the Single Page/Multi Page seems to be hidden, so we have no
clue how to go ahead with Duplex Scan.

Thanks & Regards,

well, that would depend on the scanner, and the backend, which you did
not tell us :)

Which frontend do you have selected in Edit/Preferences?

If you start gscan2pdf with the --log=log option, open the scan dialog,
quit and post the log file, I'll take a look.
