Using django signals to update status of multiple models

I'm currently working on a Django project where I have models for ClientOrders, DesignerJob, and PrinterJob. I want to implement a functionality where changes in the status of DesignerJob and PrinterJob models trigger updates to the status of the associated ClientOrders model.

For example, when the status of a DesignerJob changes from "new" to "in_progress," I want the status of the corresponding ClientOrders model to be updated to a specific status. Similarly, when the status of a PrinterJob changes, I want the associated ClientOrders status to be adjusted accordingly.

I'm planning to use Django signals to achieve this, but I want to make sure I follow best practices and avoid potential pitfalls.Here are my specific questions:

Signal Handling Approach: Should I use one signal for each model and implement all the conditions in that signal or make separate signals for each case?

Circular Signal Calling: If I have a case where say PrinterJob signal updates DesignerJob status, will it cause circular calling? But this case is very unlikely.
