I am trying to set up a USB Epson thermal printer in a posboxless environment.
I followed the instructions at:
https://www.odoo.com/documentation/user/9.0/point_of_sale/overview/setup.html#posboxless-guide-advanced
I'm getting this message when accessing /hw_proxy/status
I set 777 permissions on /dev/usb/lp0, which corresponds to the Epson printer in question.
Any ideas on what am I still missing?
Hi Perry. Sorry for the delay in replying. I ended up starting from scratch, then followed the procedure at this link:
https://www.odoo.com/documentation/user/9.0/point_of_sale/overview/setup.html
The only thing I did differently was in the following section:
"Then we need to create a udev rule that will automatically allow members of usbusers to access raw USB devices. To do so create a file called 99-usbusers.rule in the /etc/udev/rules.d/ directory with the following content:"
The file needs to be named 99-usbusers.rules, i.e. there is a letter s missing at the end of the file name in the instructions.
Let me know if you need any more help.
As a summary of all the contribution abover, two points should be aware of:
1. the file name is /etc/udev/rules.d/99-usbusers.rules2. if
useradd -G usbusers USERNAME
doesn't work, try
sudo usermod -a -G usbusers USERNAME
that's correct
Hello Daniel Holden!, i already have put the missing s, but i still having the message ''access denied'', i am working on ubuntu 14.04 thermal printer epson tm t20 with odoo 8, did you work differently? where is my mistake?sorry for my poor english =(
Olá Carlos. Hablo portugués y entiendo español . Usted puede utilizar el que sea más cómodo. :-) The only thing I can think of is that the user account was not properly added to the usbusers group (which has permissions on the device). Please check this step: Then we add the user who will run the OpenERP server to usbusers # useradd -G usbusers USERNAME On some systems (not sure why) I have had to use this instead: # usermod -a -G usbusers USERNAME
