Every B2B SaaS application generates PDFs at some point. Invoices, reports, contracts, certificates, statements. Most teams reach for the obvious tools - wkhtmltopdf, Puppeteer, Prince, or some headless Chrome wrapper - and move on. It works well enough at first. Then the edge cases start piling up, the support tickets trickle in, and suddenly your PDF pipeline is a source of ongoing friction rather than a solved problem.
Here are five signs that your current approach is costing you more than you think.
1. Your PDFs Look Different Depending on Where They Were Generated
This is the classic symptom. A PDF generated on your local machine looks fine. The same code running in a Docker container on Linux produces slightly different spacing. A customer reports that the table in their invoice is overlapping the footer. Another customer sees different fonts because the container image is missing a font package you forgot to install.
The root cause is always the same. HTML-to-PDF tools depend on a rendering engine - usually a browser - and browsers render differently depending on the operating system, installed fonts, screen resolution settings, and even the version of the engine itself. You are generating documents using a technology designed for screens, then forcing it onto paper. The mismatch is fundamental, not incidental.
LaTeX does not have this problem. It is a typesetting engine that targets fixed-size pages as its primary output. The same LaTeX source produces byte-identical PDFs regardless of where you compile it. Pressa runs compilation in a controlled environment with every font and package pre-installed, so the output is deterministic every time.
2. PDF Generation is Blocking Your User Requests
Headless browser rendering is slow. Launching a Chrome instance, loading your HTML template, waiting for CSS and fonts to load, rendering the page, and converting to PDF - this pipeline regularly takes 2 to 10 seconds per document. For a single invoice, that is annoying. For a batch of 500 monthly statements, it is a bottleneck that brings your background job queue to a crawl.
Some teams try to optimize by keeping a pool of browser instances warm. This adds memory pressure, crash recovery logic, and another piece of infrastructure to monitor. Others offload to a separate service, which helps but does not address the core problem: you are running a full web browser to produce a static document.
Pressa compiles LaTeX to PDF in seconds without a browser in the loop. There is no DOM to construct, no CSS to evaluate, no JavaScript to execute. The compilation process is purpose-built for document generation, not repurposed from a tool designed for interactive web pages.
3. Maintaining Your Templates Feels Like Frontend Development
Your PDF templates are HTML files with inline CSS, media print stylesheets, and probably a few hacks to work around page break behavior. When a designer wants to change the invoice layout, someone has to edit HTML, test it across multiple rendering engines, verify that page breaks still land correctly, and check that nothing overflows on longer invoices.
This is frontend development masquerading as document generation. You need someone who understands CSS print media queries, knows which properties your specific rendering engine supports, and can debug layout issues that only appear at certain content lengths. The maintenance burden is disproportionate to the value delivered.
With Pressa, your documents are defined in LaTeX - a language specifically designed for document layout. Page breaks, headers, footers, margins, and content flow are first-class features, not afterthoughts bolted onto a screen-oriented technology. And since modern LLMs generate LaTeX fluently, you do not need a LaTeX expert on your team. You describe the template once, and the typesetting engine handles the rest.
4. You Have No Programmatic Control Over Document Structure
Try generating a PDF with wkhtmltopdf or Puppeteer that has a table of contents with accurate page numbers. Or a document where the header on the first page differs from subsequent pages. Or a report where figures float to the top of the next page when they do not fit on the current one. These are trivial requirements in professional document production, but they are painful to implement with HTML-to-PDF tools.
The reason is that HTML was never designed to be aware of pages. CSS Paged Media exists as a specification, but browser support is incomplete and inconsistent. You end up writing JavaScript that calculates content height, manually inserts page breaks, and hopes the rendering engine agrees with your math. It is fragile and breaks every time the content changes shape.
LaTeX was built for exactly these problems. Table of contents generation, cross-references, figure placement, conditional headers and footers, automatic page numbering - these are built-in features that work reliably because the engine understands the concept of a physical page. When you use Pressa, all of these capabilities are available out of the box.
5. You Worry About Security Every Time You Generate a PDF
If your PDF generation involves a headless browser, you are running a full browser engine that can execute JavaScript, make network requests, and access system resources. This creates a meaningful attack surface. User-provided content that ends up in your HTML template could potentially trigger script execution, server-side request forgery, or local file access through the browser engine.
Teams mitigate this with sandboxing, input sanitization, and network restrictions, but it is defense in depth against a problem that should not exist in the first place. You are running a browser because your tool requires one, not because document generation inherently needs one.
Pressa compiles LaTeX, not HTML. There is no JavaScript engine, no network stack, no DOM. The compilation environment is isolated and purpose-built for typesetting. The attack surface is fundamentally smaller because the tool does exactly one thing - turn markup into a PDF - without the overhead of a general-purpose browser engine.
The Common Thread
All five of these problems share a root cause. HTML-to-PDF tools take a technology designed for interactive screens and force it to produce fixed-layout documents. The result is a constant stream of workarounds for a fundamental architectural mismatch.
LaTeX is purpose-built for document generation. It has been the standard in academic publishing, scientific journals, and professional typesetting for over 40 years. The only reason it has not been widely adopted in software is the infrastructure barrier - installation complexity, package management, and server configuration.
Pressa removes that barrier. One API call, LaTeX in, PDF out. No browser instances, no font management, no template maintenance, no security surface area from running Chrome in your backend.
If any of these five signs sound familiar, the fix is not a better HTML-to-PDF library. It is a better approach to document generation entirely.
