Why 'Print to PDF' Is the Reliable Way to Export a Browser-Built Document

Two different ways to turn a webpage into a PDF

A tool that builds something like an invoice or resume in your browser has two realistic options for getting it to you as a PDF: draw every line of text and every table cell manually using a PDF-generation library, or hand the finished, styled HTML off to your browser's own built-in "Print to PDF" feature.

Why manually-drawn PDFs are more fragile than they look

Manually positioning text means calculating exact x/y coordinates for every line, table column and page break yourself in code. Get a line-wrap calculation slightly wrong, or add one line item too many, and text can overlap or spill off the page edge — bugs that are easy to introduce and surprisingly tedious to bulletproof for documents with a variable amount of content, like an invoice with anywhere from one to twenty line items.

Why your browser's print engine handles this better

Every modern browser already contains a mature, heavily-tested layout and pagination engine — the same one that renders ordinary web pages — and its "Save as PDF" print destination reuses that engine directly. It already knows how to wrap text, break a table across pages cleanly, and keep everything correctly positioned regardless of how much content there is, because that's exactly what it does every time it renders any webpage.

The tradeoff: a small design hand-off

The one thing a page's regular author has to do is tell the browser what to hide when printing (navigation, buttons, ads) and what to show (just the document itself) using print-specific CSS. That's a one-time, straightforward step for whoever builds the page, rather than an ongoing maintenance burden every time a document's content changes.

Try it yourself

Our Invoice Generator uses exactly this approach — build your invoice, click Print, and choose "Save as PDF" in your browser's dialog for a properly paginated result, no matter how many line items you've added.
