A label printing plugin for InvenTree, which provides support for the Niimbot Label Printers. This plugin is based on the amazing work from labbots/NiimPrintX and modifications from LorisPolenz/NiimPrintX.
Install this plugin manually as follows:
pip install inventree-niimbot-plugin
Or, add to your plugins.txt file to install automatically using the invoke install command:
inventree-niimbot-plugin
The following list gives an overview of the available settings. You find them under the InvenTree plugin specific settings.
-
Printer Model Currently supported models are: b1, b18, b21, d11, d110 (but i was only able to test b1 because i don't have other printer models. Please report back if you can test other models!!).
-
Density The print density. Different models seem to accept only certain values (b1 accepts 1-3).
-
Rotation Rotation angle, either 0, 90, 180 or 270 degrees.
-
Scaling Scaling factor, from 10% to 200%.
-
Vertical Offset Vertical offset, from 0 to 200px.
-
Horizontal Offset Horizontal offset, from 0 to 200px.
Once installed, the plugin should show up under Settings -> Plugin Settings -> Plugins and be activated.
You can then adjust the printer settings under Settings -> Plugin Settings -> Niimbot Label Printer.
As a starting point, you can use my settings for the B1 printer with 50x30mm standard labels and the "InvenTree Part Label" template:
Printer Model: Niimbot B1, Density: 3, Rotation: 270°, Scaling: 60%, Vertical Offset: 50px, Horizontal Offset: 0px
You can either connect the printer via USB or bluetooth. When using bluetooth, you need to pair the printer with the machine running InvenTree (e.g using bluez-tools on terminal). The printer is then detected automatically.
The plugin system seemed to be broken in recent InvenTree docker images. I was not able to install the plugin without errors. Furthermore, i am not sure if it's even possible to access bluetooth or USB devices from within a docker image.
I therefore was only able to use the plugin with bare metal installation of InvenTree. The bare metal installation also fixed many other issues the docker image had and worked like a charm, although it takes a little extra effort.
