A label printer driver plugin for InvenTree, which provides support for Cups label printing servers. If your printer is not cups compatible, you can setup a cups printing server. This article describes how to setup a cups printing server for the DYMO LabelWriter 450 Duo. If you have a Dymo printer, you might also want to check out the dedicated inventree-dymo-plugin
which is the recommended choice because it works more performant.
Important
This plugin needs cups-devel
installed to install its dependencies. You can read more about the requirements at pycups
. If you're using apt
as a package manager run apt install libcups2-dev
before. For docker see below.
Important
For InvenTree<0.16 use this package with version 0.1.0
Goto "Settings > Plugins > Install Plugin" and enter inventree-cups-plugin
as package name.
For docker installs you need to build your own docker image based on the inventree image to install the required system dependencies. The following Dockerfile
is using a multistage build to only install what is needed onto the inventree image and do the building in a separate stage.
Note
This only works for the inventree alpine based docker image which is shipped with inventree>=0.13.
To use it you have to do some slight modifications of the docker-compose.yml
file and create the Dockerfile
as follows:
docker-compose.yml changes
diff --git a/docker-compose.yml b/docker-compose.yml
index 8adee63..dc3993c 100644
