<p>Hi there,</p>
<p>I suspect, there is a small bug in iscan_2.30.4-2_amd64.deb.</p>
<p>The problem of the bug is mentioned here: <a

<p data-sourcepos="12:1-12:183" dir="auto">In my experience, <code>scanimage
--help</code> dynamically adapts its output upon the given
options before <code>--help</code>, i.e., the stated default
values of options differ upon them. Please compare:</p>

<p data-sourcepos="53:1-53:268" dir="auto">The latter still lists
<code>--scan-area</code> and <code>--quick-format</code> as <code>A4</code>,
instead <code>Maximum</code>. In the opinion of the developer
of gscan2pdf this is a bug. I too think, he is right, as if
frontends rely on this help defaults, the user gets presented
the wrong values in the GUI.</p>
<p data-sourcepos="53:1-53:268" dir="auto">Thanks to review this
problem,</p>
