Hi, 

I have the same problem. 

I'm using Windows 7, Odoo9, I installed wkhtmltopdf and this is the path : C:\Program Files\wkhtmltopdf

Report_type="qweb-html" is working perfectly, but when I use report_type="qweb-pdf" I get the pdf with data but without Css !

I added report.url = http://localhost:8069 and

 in "Settings" > "System Parameters".

But it's still the same problem.

Anyone have any idea how to solve this please ? Thanks.

Hi,

I havent tried in odoo v9 but I did had same issue on odoo v8. What I did was the following:

1)Technical > Parameters >System Parameters (similar in odoo v9)

2)You should have 2 keys in there with the following values :

a)key= web.base.url  value = http://localhost:8069

b)key = report.url      value = http://127.0.0.1:8069/

I search a lot in this.What understand is that sometimes server take more time to proccess data than the wkhtmltopdf so thats why you get blank page.So now with this you tell the system something like to "send" data separately when  printing reports in pdf format.

Note: If you dont have both keys you can easily create them in the same window,just hit create and write down each key and its corresponding value and save.

Let me know if it helps.

Hello,

You can set parameter in setting > system parameter 

And create :

name : report.url

url : http://127.0.0.1:8069 

Hope this will help you !!
