* fix unfinished Python2 -> 3 translation * remove some six usage * annotate * fix regression in Six removal * mypy: self.enf is always defined * fix return type of cups.py * Usb idVendor/idProduct are integers * self.default_args is always defined * tweak usb_args, PEP589 is better * lp.py: reassure mypy * correctly cast call to CashDrawerError() * update CUPS test * add missing close() method in metaclass * document a bug in typeshed * query_status() returns bytes as seen in constants.py * remove more SIX usage * test examples too * remove type comment where type is annotated * adapt behavior of cups printer to match other implementations --------- Co-authored-by: Patrick Kanzler <dev@pkanzler.de> Co-authored-by: Patrick Kanzler <4189642+patkan@users.noreply.github.com>
