+No se por que gscan2pdf me junta 2 paginas en 1 cuando uso ADF Duplex, asi que he escrito este guion:
+<code>
+#!/bin/bash
+RESOLUTION="100"
+AUX_DIR="/tmp/scan/"
+SCANNER="hp5590"

+FINAL_FILE="output.pdf"
+WIDTH="200"
+HEIGHT="302"
+PER_WIDTH="76"
+PER_HEIGHT="71"
+rm -fr $AUX_DIR
+mkdir $AUX_DIR
+cd $AUX_DIR
+scanimage -d "$DEVICE" -b -p --mode Color --source "ADF Duplex" --resolution $RESOLUTION --format=$SCAN_FILE_EXT -x $WIDTH -y $HEIGHT
+cd $AUX_DIR
+for f in $AUX_DIR*
+do
+    file=`basename $f`
+    convert $file -resize $PER_WIDTH%x$PER_HEIGHT% file_reduced.pnm
+    if [ `expr $COUNTER % 2` -eq 0 ]
+    then
+        convert -rotate 180 file_reduced.pnm $SCAN_FILE_NAME$COUNTER.pnm
+        rm -fr $file
+    else
+        mv file_reduced.pnm $SCAN_FILE_NAME$COUNTER.pnm
+    fi
