A0 Size Printers: Best Models and When to Use Them

When your work contains a lot of detail, larger prints make it much easier for that detail to shine through. In these instances, A0 is a commonly chosen paper size. Architectural blueprints, engineering schematics, and high-impact posters all frequently use this size, and having a printer with A0 size capabilities can help.

In this guide, we'll explore what makes A0 printing unique. We'll also explore the top HP printer models available in 2025 that print at this size. Whether you need accurate line drawings or rich colour graphics, one of these printers with A0 size paper is sure to fit your needs.

A0 is the largest standard in the A-series. Let's take a detailed look at its specifications and applications to gain a better understanding of how organisations can use it.

A0 paper measures 841 × 1189 millimetres (33.1 × 46.8 inches). This is the largest standard paper size in the series. It provides approximately one square metre of printing area. Each subsequent size (A1, A2, A3, and so on) represents exactly half of the area of the previous size.

A0 printing is often chosen in instances where larger sizes are required for detail and/or visibility. Here are some of the areas where the format is used:

• Architecture: Building plans, site layouts, and construction drawings
• Engineering: Complex schematics and technical documentation
• Marketing: Posters and trade show displays
• Education: Diagrams, charts, and academic posters
• Art Studios: Large-format artwork and photographic prints

There are many printers with A0 size capabilities on the market. To find the right one for your needs, consider the factors below:

Look for a resolution of at least 2400x1200 DPI to get high-quality output. Higher resolution results in more precise line work and easier-to-read text. Advanced printers with A0 size, like those by HP, include colour management systems for even more precise and consistent colour output.

When evaluating a printer, look for robust roll-feed mechanisms with adjustable tension and variable-width spindles to accommodate rolls of different sizes. Your choice should also have switchable feed options for smooth transitions between A0 and other paper sizes. This should include support for both thin and thick paper rolls. Additionally, the machine should be capable of cutting the paper when printing finishes.

A good printer in A0 size will integrate easily with your existing workflows. This includes supporting the software that you use, as well as the Ethernet, Wi-Fi, or USB connections you use in your systems. Some systems, such as HP Click, even offer the ability to print remotely, providing connectivity with the printer and A0 size print capabilities from anywhere in the world.

HP's 2025 large format lineup offers several A0 printing solutions. The diverse product range covers all professional needs and budget constraints. Each of the models below offers unique advantages suited to a specific workflow or budget.

The HP DesignJet T650 provides users with a nice balance of performance and value, making it one of the best A0 printers for those on a budget. The T650 is designed specifically for CAD and engineering workflows. It places a high priority on line quality and dimensional accuracy.

The T650 offers fast processing speeds and efficient ink usage, making it ideal for high-volume technical printing. It has a robust construction with reliable paper handling for consistent performance even in demanding settings. The built-in software integrates with all of the most popular CAD applications for seamless, high-quality printing.

The HP DesignJet T850 is a premium A0 printing solution. It features advanced colour management, high ink capacity, professional-grade media handling, and more. Its 2400 x 1200 DPI resolution and eight-colour ink configuration ensure excellent colour accuracy with smooth gradients, making it an excellent option for photography and graphic design.

Photographers and design studios benefit from the T850's built-in spectrophotometer. This component automatically calibrates the colour output to provide consistent results regardless of media type. Operating costs stay low with high-capacity ink systems that keep high-volume print jobs rolling longer without interruption.

The HP DesignJet T950 is HP's flagship large format printing solution. It has been engineered to meet even the most demanding professional applications. The T950 builds upon the already impressive foundation provided by the T850, adding enhanced processing power, more memory, and greater security features to that already capable platform.

The T950 works exceptionally well for mixed-media production workflows. It can handle both technical drawings and fine art reproduction with equal ease. It features a dual-roll capability with automatic media switching, providing maximum productivity for busy design teams. For increased efficiency, the printer features remote monitoring capabilities and advanced print queue management.

To determine whether you should invest in a printer capable of producing A0 or large documents, consider the following factors:

A0 may be the largest standard paper size, but many applications can be served effectively with smaller formats, like A1 or A2. Carefully consider the requirements of your typical projects to see whether they require the full A0 canvas.

You can scale documents down from A0 to A1, though the result may compromise the clarity of fine details. Trying a few test prints of your typical documents at this reduced size will tell you whether the A0 size provides the additional clarity required to justify the upgrade.

In-house vs outsourcing is a common question across many areas of business operations. Printing is no different. Outsourced printing is expensive compared to in-house printing. However, if your print volume isn't high enough, the financial savings will not be enough. When time savings and workflow control are accounted for, companies that print 50-100 A0 pages per month typically find in-house printing to be the most attractive option.

Beyond pricing, you also need to consider turnaround times. In-house printing allows for rapid design iteration and last-minute modifications that aren't possible when you rely on outsourced printing. If you frequently work under tight deadlines, then this benefit alone may make the in-house printing option valuable.
