Or just separate template file just like for sending emails :) Because original one is somehow embedded into the code?

Hi @dwmayr,

Unfortunately I have to close this issue since this won't be fixed.
You are indeed correct that for both the PDF and ESC/POS print operations the template is hard baked into code.

The reason is that these formats are hard to work with since every shift within the layout needs to be compensated for, therefore it is almost impossible to fix this.

The only way at least for PDF's would be to embed chromium to then render a html page and use the print feature to export the pdf that way. The problem here lies in the fact that doing so would increase the project by almost 150mb's.

I hope this clears up why this is make in this way.

Kind regards,
Glenn
