How to Get Page Number Variables in Jinja for Custom Rendering in Print Designer

I am working on implementing a print format for a dot-matrix printer using a print designer. I need to include logic in my Jinja template to render content differently based on the current page number and total number of pages.

For example, I want to achieve something like this:

{% if current_page != total_pages %}
    Continue...
{% endif %}

How can I access or calculate the current_page and total_pages variables in Jinja for a custom print format?

Any help or guidance would be greatly appreciated.
