I am trying to call the function in GIMP file-print-gimp. Do you have example of the arguments that are needed and the correct syntax? I am getting the error "Invalid types specified for arguments". Below is a copy of the script as I entered it into script-fu. (file-print-gimp 0 "home/eds_cm/screen.xwd" "home/eds_cm/screen.xwd" "lp -s -dhpcp1160 -oraw" "DJ9xxVIP" "/usr/share/printconf/foomatic/data/DJ9xxVIP-530418.foo" 1 "300" "Letter" "Plain" "Tray1" 1.0 100 -1 -1 -1 1 1 1 1 1 0 2 2 1 "\0" "Adaptive" 0). In addition, I want to use this to print out a screenshot from the xwd command. Can I use gimp -b to do this from the command line. By the way the screenshot is referenced above as screen.xwd. Thank you in advance for your assistance.
