Device initiated scans require a daemon on the computer that knows what
to do when the button on the scanner is pushed. Please have a look
scanbd https://sourceforge.net/projects/scanbd/. Scanbd is designed on
top of sane. The deamon continuously polls the scanner to see if work
needs to be done. It will then use saned to do the actual scanning.
Results will be stored on disk in the resolution you configured in the
scanbd configuration.

Xsane does have a button-controlled scan option that allows it to wait
for a key press as well. But that is used to delay scanning until the
key on the scanner is pressed.
