#
# Setup notes:
#
#  * Implemented an tested on a Debian 'etch' system; also works on 'lenny' and 'squeeze'
#  * You need sane-utils and libtiff-tools installed
#  * Find your scanner using sane-find-scanner and scanimage -L
#  * Scanner configuration is in /etc/sane.d/<manufacturer>
#  * It does not work to pipe all of these commands together, for some reason
#
# Hints:
#
#  * Make sure your user is in the scanners group
#  * It may be possible to exclude the --device switch if your default scanner works
#  * BUT if your scanner gets recognized in more than one way, you must list it explicitly
#
# My personal script previously used explicit device "epkowa:libusb:002:007",
# an Epson Perfection 1650.  I was unable to rely on the default device.
# Currently (as of March of 2011), the default device seems to work properly
# again, so I've removed the --device switch.  If you have one device but its
# name keeps changing, you could try using the $DEVICE variable that I've set
# up below.
#
# I previously used the --quick-format=Letter switch.  However, that option
# seems to have disappeared in my current version of the tool (1.0.21).
# Everything seems to work without it, so I guess this doesn't matter.

# Configured commands
#DEVICE=$(scanimage -L | head -1 | sed 's/^device `//' | sed 's/. is a.*$//')
#SCAN="scanimage --progress --device=epkowa:libusb:002:007 --format=tiff --mode=Gray --resolution=300"
#SCAN="scanimage --progress --device=$DEVICE --format=tiff --mode=Gray --resolution=300"
SCAN="scanimage --progress --format=tiff --mode=Gray --resolution=300"
CONVERT="tiff2ps -z -h11 -w8.5"
PRINT="lp -d samsung"

# Print a starting

# Scan whatever is sitting in the scanner, to a TIFF file
print "Scanning..."
${SCAN} > ${TIFF_FILE}
if [[ $? != 0 ]]
then

   exit 1
fi

# Convert the TIFF file to a Postscript file
print "Converting..."
${CONVERT} ${TIFF_FILE} > ${PS_FILE}
if [[ $? != 0 ]]
then
   print "Error converting document."
   rm -f ${TIFF_FILE}
   exit 1

${PRINT} ${PS_FILE}

# Clean up
print "Cleaning up..."
