I'm currently encountering some potential rounding issues with the PDF page size where I have to use an additional few 10ths of a millimetre on the width and height for the pages, the page s declaration in my CSS, and also the CSS height of my section s to render mostly correctly. Even after adding the extra mm to cover the issue, the width then increases by about mm on either side of the page, only when Puppeteer is used to generate the PDF, but not when printed as PDF directly from my local Chrome The removal of the additional mm breaks the layout in both local Chrome and puppeteer rendered PDFs.

Possibly similar issue to There is a horizontal page gap on either side of each page of about 1mm.

Should not need to use any additional mm adjustment - raw sizes should render as expected. Did you test both with the same Chromium revision? As far as I've seen the source code, the rendering and the calculation does not happen via the API, but in Chromium. There may also be differences between Chrome and Chromium here. I've been facing the same issue. I think you are right in that this problem relates to rounding errors.

In the specific use case I'm dealing with, I had successfully gotten other page sizes flush with the edges by, as you mentioned, adding on fractions of a MM by trial and error. The problem is made even worse when the document consists of multiple pages, and then like 20 pages down you've got 20 pixels of the previous page poking in through the top. Doesn't make a difference with emulateMedia is 'print' or 'screen', or if margins are set or not set.

I've noticed a few inconsistencies when trying to use the headerTemplate and footerTemplate options with page. Can someone familiar with the implementation explain how it actually works?

From the Puppeteer Documentation :. We can learn from the the Puppeteer source code for page. The Chromium source code for Page. After further digging, we can see that Chromium has a concrete implementation of a class called SkDocument that creates PDF files. Background : The PDF file format has a headera set of objects and then a footer that contains a table of contents for all of the objects in the document the cross-reference table. The table of contents lists the specific byte position for each object.

The document uses SkWStream::bytesWritten to query the offsets of each object and build the cross-reference table. The catalog is responsible for assigning object numbers and generating the table of contents required at the end of PDF files. In some sense, generating a PDF is a three step process. Finally, in the third step, the header is printedeach object is printedand then the table of contents and trailer are printed. The printing implementation is in PrintPageInternal.

It uses two separate WebFrame s — one to render the content, and one to render the header and footer. After this, the rest of the contents of the page are printed on the same canvas within the bounds defined by the margins. I'm guessing this special frame is what prevents the header and footer from sharing the same resources styles, fonts etc. It probably isn't setup to load and wait for any additional resources requested by the header and footer templates, which is why the requested fonts don't load.
