Connect a Printer
=================
When using your *IoT Box* in Odoo, you could need to use a printer.
Doing so is easy and convenient as it can be done in a few steps. Then,
you can use it to print receipts, orders or even reports in different
Odoo apps.
Connection
==========
To connect the printer to the *IoT Box*, you just have to combine the
two by cable.
.. note::
Sometimes, a serial to USB adapter may be needed.
If your printer is a `supported
one <https://www.odoo.com/page/iot-hardware>`__, there is no need to set up anything
because it will be automatically detected as soon as it is connected.
.. note::
The printer can take up to two minutes to appear in your devices list.

In some cases, you may need to restart the box and download your
printers drivers from the box. To do so, go to the *IoT Box Home
Page* and click on *drivers list*. Then, click on load drivers.

Link the Printer
================
To Work Orders
--------------
You can link *Work Orders* to printers via a *Quality Control Point*
to print labels for manufactured products.
To do so, you need to create a *Quality Control Point* from the
*Quality* app. Then, you can select the correct manufacturing
operation and the work order operation. In type, choose *Print Label*
and hit save.

automatically print it.
Print Receipts from the PoS
---------------------------
You can link a printer to your *Point of Sale* app so you can print
receipts directly from your *PoS*.
Doing so is really easy. Go to your *Point of Sale* app and open your
*PoS* settings, under *Configuration*. There, click on *Edit* and
check the *IoT Box* feature. Then, enable the *Receipt Printer*.

Now, on your *PoS* view, you will be able to print different kinds of
tickets: **receipts**, **sale details** and **bills**.
For the receipt, it will be printed once the order is validated. The
process is automated when you enable the feature in your *PoS*.
Sales details can be printed by clicking on the printer icon on the
navbar at the top of the *PoS*. It will print the details of the sales
of the current day.
