The solution:

In file /etc/odoo/odoo-server.conf

server_wide_modules = web,hw_proxy,hw_posbox_homepage,hw_scale,hw_escpos

In file /etc/init.d/odoo

PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/bin

DAEMON=/opt/odoo/odoo.py

NAME=odoo

DESC=odoo

CONFIG=/etc/odoo/odoo-server.conf

LOGFILE=/opt/odoo/logs/odoo-server.log

PIDFILE=/var/run/${NAME}.pid USER=usuari

.....

function _start() {

    start-stop-daemon --start --quiet --pidfile $PIDFILE --chuid $USER:$USER --b ackground --make-pidfile --exec $DAEMON -- --config $CONFIG --logfile $LOGFILE

}

......

Thank you for your response.

I am following the Posboxless installation on the do website https://www.odoo.com/documentation/user/9.0/point_of_sale/overview/setup.html

"

Start the local Odoo instance

We must launch the Odoo server with the correct settings

$ ./odoo.py --load=web,hw_proxy,hw_posbox_homepage,hw_posbox_upgrade,hw_scale, hw_scanner,hw_escpos

"

This sort of works from the command line the receipt printer prints the slip but I need to start it automatically. The Pos still cannot see the devices.

In addition I am now getting ESC/POS Error Access Denied

I am still very confused with this installation.
