|

|
||
<p>
|
||
Absolutely. But I`m not sure about scan`s performance because after killing<br>
|
||
xscan (Cancel button doesn't work) the current pass is finished with the <br>
|
||
expected performance. Scan crashes before the first pass is done.<br>
|
||
<p>
|
||
Here are some measurements with xscan and xscan form Arno A.(xscanaa):<br>

||
