PDF print is broken and Letterhead in PDF not appearing

[fnrfarid]

Hi,

I’ve recently installed v12 in a local server. Everything seems fine [so far], but I’m having trouble generating PDF prints. The PDF format is broken while the preview works just fine.

The preview looks like:

And the PDF looks like this:

All other settings related to printing is okay. What might be causing this? Can anyone enlighten me the solution?

Thanks in advance.

Regards

Thanks. I did tried to find a solution and found a thread regarding the host name. I added the hostname in the config file but still the same error.

I will read the discussions again in the morning.

Thanks for your help.

Thanks man! I found the issue.

Wkhtmltopdf layout error

Hi @jodeq, there can be different reasons that can lead to this. I would guess that wkhtmltopdf cannot access the references resources (CSS and imgs). This can be caused e.g. by a firewall blocking these intra-zone calls the hostname configuration of ERPNext (see site/site1.local/site_config.json should contain "host_name": "https://www.yourdomain.com",) by a missing libssl1.0-dev (normally missing in Debian 9) You can also troubleshoot by extracting the html that goes to wkhtmltopdf by temp…

The “libssl1.0-dev” was missing. Version was “libssl-dev”.

Thanks everyone.

Hi fnrfarid
Please can you share details how did you fix this?

[fnrfarid]

You have to add the hostname in your siteconfig file. Check this Wkhtmltopdf layout error - #4 by lasalesi

[zahidshuja]

already done this but no luck

[zahidshuja]

Its fixed there was small mistake i added
“host_name”: “https://www.yourdomain.com:portnumber”

[shrikant9867]

@zahidshuja can you please explain which port number you used , Is it Nginx 80 , 443 or other ?

Same problem, fixed after.
1.- installing libssl1.0-dev (sudo apt-get install -y libssl1.0-dev)
2.- Adding hostname in site_config.json ( “host_name”: “https://www.yourdomain.com",) in my case , no need to add port, because i already have “nginx_port”: 8001 in site_config.json file

Hope this helps

“host_name”: “IP_address_of_the_server:site_port_number” worked for me. Thanks.

Just installing libssl1.0-dev worked after PDF print broke after updating ERPNext.

[pioneerpathan]

Thanks. It helped me. In case of SSL based sites also it worked.

I checked on my /etc/resolv.conf and it was not pointing to my DNS server. After I modified it and reloaded my network, it worked!

I am having trouble with the generating pdf in k8s production environment.
The official docker-compose setup run ok though.

Can someone give me some pointer on how to fix the 504 time out error of generating pdf in k8s ?

I have also tried to install libssl-dev apt-get update & apt-get install libssl-dev
and disable all the letter head to make sure that there is no private image but also no luck

[luulmoon]

logs of the error. I tried to play around with the host_name in site_config but no luck yet

probably need to setup break point in pdf.py and change the href following this suggestion

can’t even put a break point in

"program": "${workspaceFolder}/frappe-bench/apps/frappe/frappe/utils/bench_helper.py",

also gives timeout

I am having the same issue, have added the hostname in the site config file but have had no luck, I added the IP Address but no luck, I tried to install libssl1.0 but have had no luck.

I have done this on ERPNext 14 and 15

All below I have tried but still, I can’t get it right.

“host_name”: “http://myip:portnumber”
“host_name”: “http://myip”
“host_name”: “http://www.domainname:portnumber”
“host_name”: “http://domainname:portnumber”
“host_name”: “http://domainname”
