Since the fix of the QR bill headers (see task-3241502, PR:https://github.com/odoo/odoo/pull/130478), the print in batch functionality raises a stack trace.
This is because the render_qweb_pdf_prepare_streams method in base/ir_actions_report.py wasn't meant to handle multiple pages report without specific titles in its HTML structure, which is here the case since the QR bill fixing merges the top of one page with the end of another, therefore creating a peculiar structure.
In those cases we can consider that if each non-generated stream corresponds exactly to one page in the PDF reader, this is a simple batch printing case and we can just handle each page separately.
