Im using python to draw simple graphics. However, as I would like to print the graphics as A4 pages with my printer, Im looking for a way to automatically generate new pages from a python script. Has anyone done this before and can help me?  I have tried using the inkex library without any luck. 

There is an example ( a zipped extension attached to my post ) here. https://inkscape.org/it/forums/questions/how-to-put-each-imageobject-into-a-separate-page-and-image-fit-the-page/

One change I would make is to add the offset to the 2nd page to avoid overlapping.

Thank you so much for your help ! I'll consider modifying it :)  My last step is to figure out how to run this directly from python as a plugin/import. 

Something like:

Create a new venv in python

Activate that venv, and use pip to install Inkex.

Yes, Im able to run python, but I need to be able to run the script from another python script with inputs etc.  

Now I'm importing the script (using import xx as abc). I need to be able to give a svg filename as input to the extension script (and some additional parameters) and then get the changed file as output. 

It's not really an extension if you don't use the main Inkscape program :)

If you want to completely avoid the Inkscape main program and just use inkex in python.

You can load svgs using the load function.

This script ( inkex standalone ) shows how to load svg files from a folder:
