Thanks Raaj Mishra for reply,

point of sale --------> Configuration --------> Bar code Nomenclatures and then

click on product bar codes (where type is unit product and Encoding method is any)

i changed it from EAN13 to Any but it's can't work for me.

i read code according to your instruction

method is (if I'm not wrong)

def report_barcode(self, type, value, width=600, height=100, humanreadable=0):

if i will change it like this, is it work?

def report_barcode(self, type='EAN8', value, width=600, height=100, humanreadable=0):

Hi Usman,Yes that's right method you picked, but I am not sure about type='EAN8', need to give a try for that.

Thanks Raaj Mishra again reply...

i changed it but can't work...

now i change in xml file where pass parameter... From this code to

<tr style="width: 1in;">

<td style="border: 2px solid black;text-align: center; vertical-align: middle;" class="col-xs-5">

<img t-if="product.barcode" t-att-src="'/report/barcode/?type=%s&amp;value=%s&amp;width=%s&amp;height=%s' % ('EAN13', product.barcode, 600, 150)" style="width:100%;height:20%;"/>

<span t-field="product.barcode"/>

</td>

To this code

<tr style="width: 1in;">

<td style="border: 2px solid black;text-align: center; vertical-align: middle;" class="col-xs-5">

<img t-if="product.barcode" t-att-src="'/report/barcode/?type=%s&amp;value=%s&amp;width=%s&amp;height=%s' % ('EAN8', product.barcode, 600, 150)" style="width:100%;height:20%;"/>

<span t-field="product.barcode"/>

</td>

but still generating EAN13 code as too
