jan.tosovsky.cz@ Thanks for the issue.

As per the above description this is a Feature Request for Horizontal pagination while printing
Hence marking this issue as Untriaged and requesting Dev to look into the issue and help further.

Thanks..

If splitting is implemented in the webapp, there is no way to determine available paper sizes. So there has to be a set of typical sizes, or custom ones, from which user can select (there are lot of formats https://en.wikipedia.org/wiki/Paper_size).
It means the webapp has to implement UI and the processing (e.g. duplicating graphics on the HTML page and setting the proper viewport for each instance).
However, there is still a risk a different size will be chosen when printing (human error).
All this could be simplified by moving that pagination settings into the print preview phase.

Do you have a specific example for this? I can't tell from the description if this is for a webpage or for a SVG file or both.

This feature is intented for general use. Once the content width overflows the medium width, there should be an option to enable the horizontal splitting. This feature would be disabled by default. Once enabled, the bounding rectangle of the content would be divided into separate pages, even empty (e.g. narrow long HTML page with one or more wider images would produce lot of blank pages, which is IMHO Ok).

One of use cases is attached. It is a simple HTML page with the rectangular inline SVG graphics. I'd like to print it in exact dimensions (500 x 300 mm). Unless I have printer of the size ISO A2+, the graphics needs to be split. The total number of pages depends on the selected medium.
