OK, good. What this tells us is this:


        open -a Preview ${FILES}

from within a shell script (gm-print_doc) works just fine
(you saw Preview) while doing the same from within

        for filename in filenames:
                cmd_line = [
                        r'open',                                # "open" must 
be in the PATH
                        r'-a Preview',                  # action = Preview
                _log.debug('printing with %s' % cmd_line)
                        mac_preview = subprocess.Popen(cmd_line)
                except OSError:
                        _log.debug('cannot run <open -a Preview>')
                        return False
                if mac_preview.returncode != 0:
                        _log.error('<open -a Preview> returned [%s], failed to 
print', mac_preview.returncode)
                        return False

        return True

does not (as documented in the GNUmed log).

I am modifying so you can run it on your Mac like so:

        cd gnumed/client/pycommon
        python test

and give us the results thereof.

It would also be helpful to check the Mac OSX documentation
for "open" and/or "Preview" to find out what the exit code 1
is supposed to mean - perhaps it is entirely correct that
this returns 1 rather than 0 ?

Can you modify gm-print_doc to read:

# Darwin/MacOSX ?
if [ "${CALL_PRINTER_MANAGER}" = "" ]; then
        SYSTEM=`uname -s`
        if [ ${SYSTEM} = "Darwin" ]; then
                CALL_PRINTER_MANAGER="open -a Preview ${FILES}"
                echo "exit code: $?"
                #CALL_PRINTER_MANAGER="open ${FILES}"

at the appropriate place. Then please call it like so:

        cd gnumed/external-tools/
        ./gm-print_doc some-existing-file.pdf

and tell us what's printed for exit code.
