OK, that’s the bare minimum, but wouldn’t it be more elegant to give
the user some feedback that the problem is solved, e.g. by
auto-closing the error message box, or by changing the status line?
I don't think it's really needed. Installing paper into ADF is a
physical action. I don't think user needs a confirmation from computer
that paper was actually installed; user knows it by feeling from its
fingers.
BTW, some users missing push-mode scan, totally missed from SANE. But
it requires the whole image logistics to be rethought: user presses
some buttons at scanner, scanner connects the computer, some daemon
accepts this connection, then somehow GUI popup should occur with a
question, how to handle received image.
It doesn't fit well the UNIX multiuser model. At what desktop this
popup should be open? (unlike UNIX, on Windows current terminal
session has a very special role in respect to other system).
Although I have not used it before, but there is a scanbd daemon that I
believe allows actions to be linked to button presses.
The problem is that it ties up the device so hardly a great solution as
it stands in a multi-user environment.
As ever, wiring something up behind the scenes is one thing. Making it
usable for ordinary Joe and Jane Public with GUIs and the like to set
up
actions on button presses is the bigger issue. Most people don't like
poking around in config files. :(
I agree, we should allow the configuration of the scanners.
The scanner is of Canon or Epson or XXXX brand, and only activate the
necessary backends.
It would be necessary to be able to configure the scanner (what allows
the configuration of cups), a device is associated with a backend, it is
the user who chooses.
He can make several configurations.
We can set priorities (free driver ++), for the automatic configuration.
