I hope can use the method directly from Trytond instead. Below is my code: 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) > > -- > Cédric Krier - B2CK SPRL > Email/Jabber: cedric.kr...@b2ck.com > Tel: +32 472 54 46 59 > Website: http://www.b2ck.com/ -- You received this message because you are subscribed to the Google Groups "tryton-dev" group.
