<EM>&gt; Hi,
</EM><BR>
<EM>&gt; I'm about to start developing a piece of equipment that requires an A4
</EM><BR>
<EM>&gt; area to be imaged, and then an XY stage will print on the imaged area.
</EM><BR>
<P><EM>&gt; It seems that the cheapest and most compact way to capture the image is
</EM><BR>
<EM>&gt; with a scanner of some description, however we would like to avoid
</EM><BR>
<EM>&gt; having to move a flatbed scanner around. Does anyone have any experience
</EM><BR>
<EM>&gt; with something like a page scanner that might be appropriate. The other
</EM><BR>
<EM>&gt; option might be to pull apart a flatbed and try to use the mechanism,
</EM><BR>
<EM>&gt; but I'd like to avoid this. Does anyone have any ideas about appropriate
</EM><BR>
<EM>&gt; products that have reasonable SANE support?
</EM><BR>
<P>You didn't say how accurate the positioning had to be.
<BR>
<P>How about a video camera mounted above the stage, and a frame
<BR>
grabber card. Then put some marker on the back of the print
<BR>
mechanism so the camera can align that too.
<BR>
<P>As far as I'm aware, SANE doesn't support video cameras...
<BR>
<P><EM>&gt;
</EM><BR>
<EM>&gt; Thanks
