I have a report to print labels, in it I have:

<img t-att-src="'/report/barcode/?type=%s&amp;value=%s&amp;width=%s&amp;height=%s' % ('Code128', label.default_code, 600, 150)" style="width: 40mm;height: 12mm;horizontal-align: center"/>

On the report the barcode is not printed (a blank area), but if I change the report type to html, then it works fine and the barcode is displayed on the screen, but I need it in PDF of course for printing.

I tried with wkhtmltopdf versions: 0.12.1 , 0.12.3 , 0.12.4 , 0.12.5

What could be wrong?

Reportlab is properly installed (in html the label with barcode is displayed correctly, testing /report/barcode... in browser works fine), so I think the problem is not the same, I believe it is actually related to wkhtmltopdf.

Found this: https://github.com/odoo/odoo/issues/3234 -->

Another thing to check is that the 'web.base.url' system parameter is set correctly - it's especially easy to get caught out by this if you've changed the default XML-RPC port. I've got Nick-OpusVL to thank for highlighting this little gotcha: #1105

So  I corrected report.url and web.base.url because those were still pointing to the production environment instead of this new testenvironment: solved my problem

Can you explain

OdooBot
- try in your browser:  http://localhost:8069/report/barcode/Code128/test-0001
does that show the barcode:
yes-> check system parameters
no-> install reportlab

system parameters:
set report.url to http://127.0.0.1:8069

That's what solved it for me.

Hi,

Check whether the Python package reportlab is installed or not. If not install it and also refer this similar question already asked and solved: https://www.odoo.com/forum/help-1/question/the-barcode-is-not-displayed-in-qweb-report-odoo-92297


Thanks
