The first log line shows:

2026-02-27 21:03:29,685 ERROR [backend.app.services.virtual_printer.manager] Cannot create directory /app/data/virtual_printer/uploads: Permission denied. For Docker: ensure the data volume is writable by the container user. For bare metal: run 'sudo chown -R $(whoami) /app/data/virtual_printer'

Secondly your Docker network is not running in host mode:

"network_mode_hint": "bridge"

that will cause all the network related errors in logs.

I solved that permission problem yesterday already (just chmodded the folder)
For the docker network, i don't understand, i use the provided docker compose with the install script :

root@casaos:/opt/bambuddy# root@casaos:/opt/bambuddy# cat /opt/bambuddy/docker-compose.yml
services:

Too quick! We first need to get Bambuddy running properly!

Bambuddy looks like it's running properly, I can manage my printers from there
The issue is specifically the virtual printer feature

OK....so for the virtual printer SSDP is mandatory and SSDP requires network mode host. Without mode host, it cannot work.

There must be something on your system. I know for 100% sure, that it shows

"network_mode_hint": "host"

when Docker network is in host mode. But yours shows

"network_mode_hint": "bridge"

I'm very sure that this is the problem.

Are you running Portainer or something like that? I'm also wondering what Docker version you are running (since your OS is quite old - Debian 11)?

Also, i'm running CasaOS on this server.
I think the container is actually in host mode :

Very strange. What else? Oh yes, iptables rules are set?

Just a classic ISP router with a 192.168.0.0/24 range
The server is a Lenovo tiny pc, baremetal debian 11 with CasaOS installed (should not interfere with bambuddy), and have a DHCP ipv4 and 2 aliases :

# The primary network interface
allow-hotplug eno1
iface eno1 inet dhcp

auto eno1:1
iface eno1:1 inet static
    address 192.168.0.201
    netmask 255.255.255.0

auto eno1:2
iface eno1:2 inet static
    address 192.168.0.202
    netmask 255.255.255.0

My laptop is on the same subnet, over WiFi.

Here's the screenshot you requested :

I didn’t thought it was mandatory, since I want to queue prints to dispatch them on different printers at once after sending…
Sorry for the bothering if that’s the issue

I’ll try setting one when I get back at home

@maziggy I did the same thing with a printer selected, and the issue remains the same.
