Actually, it does. You need to simply echo STDIN to STDOUT
after you determine that the printer is active and ready,
and then exit with 0 status:
#!/bin/sh
if do_magic_things_to_determine_if_printer_active ; then
cat
fi
exit 0

Strange, I do not get this when I use this as a printcap entry...
It works fine.
Try the latest version and tell me what happens...
