From ink pens to pixels—how technical printing got its start

It wasn’t that long ago that technical drawings were created by hand—meticulously crafted with rulers, compasses, and ink pens on massive sheets of paper. Engineers and architects hunched over drafting tables for hours, carefully labelling every angle and line. Every revision meant starting again. Every large project involved endless physical storage and tedious reproduction techniques like blueprinting.

Fast-forward to today, and things have changed dramatically. The move from analogue to digital has revolutionised technical printing—not just in terms of speed, but also in accuracy, scalability, and collaboration. We’ve gone from fragile vellum sheets to high-resolution CAD files and from light-sensitive ammonia-based prints to water-based pigment inks produced on high-speed plotters. That journey has transformed how we build cities, design infrastructure, and produce signage.

In this article, we’ll explore the evolution of technical printing, with a special focus on how the HP DesignJet series—available through Dimix—has redefined the standard for technical drawings, GIS output, and CAD plans. We’ll also show how to choose the right printer for modern workflows and link to our deep dive on the T-Series vs XL-Series for those evaluating their upgrade options. Plus, you can explore all compatible large format printers on the Dimix solvent printers category page.

The CAD revolution—and the need for new printing technology

The biggest shift in technical printing came with the rise of Computer-Aided Design (CAD). Suddenly, engineers, architects, and planners were working with digital files instead of physical drawings. That allowed for greater precision, faster revisions, and enhanced collaboration across teams and locations. But it also created a new challenge: how do you accurately reproduce those digital designs on paper?

Enter the wide-format technical printer. In the early 90s, HP introduced the first DesignJet plotters, capable of interpreting CAD data and rendering it into precise, scalable output. These machines transformed the industry by offering:

• Higher resolution than traditional blueprinting.
• Faster turnaround times for design changes.
• Digital storage and repeatability of print jobs.
• Media flexibility, allowing architects and engineers to choose paper, film, or presentation materials.

What started with basic inkjet systems has evolved into today’s lineup of DesignJet T-Series and XL-Series printers, capable of producing hundreds of large-format drawings per day with pinpoint accuracy. These aren’t just plotters—they’re powerful workflow machines, often integrated with HP SmartStream, equipped with PostScript support, and secured with HP Wolf Security.

In the next section, we’ll take a closer look at how HP DesignJet printers continue to shape the modern technical print landscape—and what that means for your business.

HP DesignJet: Leading the transition into the modern era

As CAD software evolved and the demand for fast, accurate technical output increased, HP DesignJet printers became the industry benchmark. What set them apart wasn’t just print quality—it was the ability to handle complex, data-rich files with minimal user intervention. Over the years, HP continuously refined the DesignJet line to meet the changing needs of architects, engineers, GIS professionals, and signmakers alike.

Today’s HP DesignJet models—like the T2600, T1600, and XL3600—deliver more than just sharp lines and clean fills. They’re equipped with:

• Advanced processing power to handle layered PDFs and CAD files.
• PostScript support, which ensures every detail is rendered faithfully (as we explain in this PostScript-focused blogpost).
• HP SmartStream compatibility for better file management and production oversight.
• HP Wolf Security, guarding sensitive project data at every level of the workflow (see our full guide to print security).

For signmakers and technical print professionals in Belgium and the Netherlands, this means a smoother experience—less troubleshooting, more reliability, and faster delivery of precise technical documents. Whether you're printing zoning maps in Antwerp or engineering plans in Groningen, these devices have the flexibility and muscle to keep up with your workload.

If you’re upgrading from an older printer—or even from manual workflows—there’s no comparison. The DesignJet ecosystem offers a seamless bridge from digital file to physical output, built specifically for the technical sector. And when sourced from Dimix, you also get expert support tailored to your region and industry.

How technical printing fuels today’s signmaking business

While technical printing might seem like it’s all about architecture and engineering, it plays an increasingly important role in modern signmaking as well. Many signmakers now handle more than just visual graphics—they also print plans, layouts, permit drawings, and construction visuals for clients in building, public works, and infrastructure sectors.

With HP DesignJet printers, you can offer:

• In-house plan printing for architects or contractors you work with.
• On-demand technical posters or schematics for job sites.
• Visual overlays and site graphics created from GIS data.
• Durable media printing for field conditions or outdoor use.

This opens up new revenue streams and lets you position your business as a one-stop solution—not just for banners and signage, but for all large format printing needs. And because the DesignJet series is so versatile, switching between high-precision CAD work and vibrant colour graphics is seamless. Pair this with HP Carepacks (discussed in our blog on maintenance) and you have a robust, future-proof setup.

The evolution of technical printing isn’t just history—it’s a window into how signmaking businesses can expand and differentiate in a competitive market. And Dimix is here to help you do just that, with tailored printer solutions, workflow tools, and expert advice across Belgium and the Netherlands.

From bulky plotters to integrated workflow solutions

One of the most striking aspects of technical printing’s evolution is how printers have transformed from single-function devices into full workflow hubs. Where early large format plotters focused solely on output, today’s HP DesignJet models are designed to integrate seamlessly with your business systems, software, and team dynamics.

For example, take the HP DesignJet T2600. It’s not just a printer—it’s a multifunction device that combines printing, scanning, and copying, allowing project teams to digitise, annotate, and redistribute technical drawings in one streamlined process. With cloud connectivity and secure job release, files can be managed remotely while keeping sensitive data safe—especially important in public infrastructure work and tender-based projects.

Then there’s the XL3800, a workhorse built for high-demand environments where hundreds of drawings may be printed daily. It includes dual-roll functionality, a built-in stacker, and blazing-fast output speeds—making it perfect for municipal offices, technical print rooms, and busy signmakers needing reliable throughput.

This convergence of features turns your printer into a productivity asset, rather than a simple output tool. When paired with smart software like HP SmartStream, you can queue, preview, and manage batches of jobs from multiple team members, ensuring no time is lost in translation.

And best of all? When you partner with Dimix, you get support that’s just as modern as your machine—from tailored installation to ongoing service via HP Carepacks. We make sure your workflow isn’t just up to date—it’s ahead of the curve.

Final thoughts—why understanding this evolution matters

Understanding how technical printing evolved—from manual drafting to today’s intelligent, high-speed devices—isn’t just an academic exercise. It’s a valuable lens through which to evaluate your current setup and plan your next steps. Whether you’re still relying on outdated equipment or looking to diversify your services, recognising the power and flexibility of modern HP DesignJet printers can help you grow your business with confidence.

Technical printing is no longer a niche operation—it’s a core service for architects, engineers, contractors, and yes, signmakers. The ability to print precise, scalable, and presentation-ready documents is something clients value more than ever. With options ranging from the compact T850 to the powerful XL-Series, there’s a DesignJet model for every business size and ambition.
