PagedJS - Chrome Headless - Partial Rendering Problem

[canerozdemircgi]

When using paged.js with google chrome headless in order to print pdf, it goes to the stage of printing as pdf before paged.js has able to finish its work.
Any way to overcome this ?

hi there.

you can check how it’s done on pagedjs-cli repo (or simply it :D)

https://gitlab.coko.foundation/pagedjs/pagedjs-cli/

tell us if that helps.

Thank you but the environment is not at my control, there are only chrome and firefox.

i’m curious how do you use chrome headless? without pupeteer?

in any case, do you have the right content when you’re not headless?

do you have some code for us to try?

Attached an example html

Running this command
chrome --headless --disable-gpu --run-all-compositor-stages-before-draw --virtual-time-budget=5000 --print-to-pdf-no-header --no-pdf-header-footer --print-to-pdf=example.pdf example.html

It works if I set virtual-time-budget like 2147483647 (which is literally the max value it can take, it also works close values like 1000000000), but that is a quite bad solution and still doesn't guarantee. I presume the underlying reason is async functions of paged.js

Take a look at the Drupal module printable, which I also maintain. I've got a file named waitFor.js (from memory) in there, that provides different ways of waiting for pagedJS to do its work. It might be helpful.
