@hugho-ad
FYI @smetl
This is the consequence of a feature. Reports are rendered in batch, with only one pass in wkhtmltopdf.
Then, we use the PDF tags that h tags make to redivide into each object's report

@kebeclibre

That looks like a bug, nice feature, but is still a bug, you can NOT leave these gaps that made crash simple print report action

@kebeclibre
Please re-open it, since is not fixed or informed across any documentation

@hugho-ad Hello. It's not a bug. The current implementation only supports one tag per document to be able to split the result of wkhtmltopdf (1 outline = 1 document). This is a choice made to greatly improve the performance when generating the pdf.
