POS Odoo 8 on Mac
by
Alejandro Perez Cosio
Hello all,
I got a TM20II printer and I’m trying to run Odoo 8 with hw_escpos module to print the receipts from my macbook (OS X 10.10.2), but when I install hw_escpos and go to localhost:8069/hw_proxy/status I get some errors at the console:
------------------------------------------------------------
Traceback (most recent call last):
File "/Users/ale/Projects/odoo/addons/hw_escpos/controllers/main.py", line 158, in run
printer = self.get_escpos_printer()

printers = self.connected_usb_devices()

if printer:
UnboundLocalError: local variable 'printer' referenced before assignment
(I’m also getting this last one in ubuntu)
After this, I’m getting a 500 internal error at the browser and if I try to print a receipt from the POS, I get this (which seems to be fine), but nothing is being printed.

Did you ever had these errors? how can I solve it?
Thanks in advance, regards
Alejandro
