Emulate odoo pos BOX

1-instruction.rst

hw_escpos

• apply patch

• install hw_escpos on odoo

• run odoo with -d DB_WITH_HW_ESCPOS --db-filter=DB_WITH_HW_ESCPOS

• in new terminal run

  tail -f /tmp/printer

On printing:

• some binary data is sent to /tmp/printer
• odoo prints logs with unparsed data (see example.html)

screenticket

Optional.

It seems that it doesn't work and need to be fixed

git clone https://github.com/it-projects-llc/screenticket.git
cd screenticket
sudo apt-get install libqt4-dev qt4-qmake
qmake
make
sudo make install

POS

• set Receipt printer checkbox in pos.config and set ip equal to 127.0.0.1
• open POS interface (at any database, including one on runbot)
• print ticket
