I am using Relatio to do this job, please see my example as below:
from relatorio import Report
class BarcodeLabel(Workflow, ModelSQL, ModelView):
@classmethod
def print_lpn(cls, records):
report = Report(abspath(join(dirname(__file__), 'lpn.odt')),
ODT_MIME)
data = report(records=records).render().getvalue()
file_name = join(dirname(__file__), 'output_basic.odt')
open(file_name, 'wb').write(data)
