Within the constantly changing fields of architecture, engineering, construction (AEC), geographic information systems (GIS) and print-for-paid services, dependable large format printing solutions are crucial for overall productivity. Plotter printers are essential for project precision and flexibility, and are used for producing complex technical diagrams, attractive posters and accurate GIS maps. This article delves into the various types of plotter printers, their extensive uses and advantages and their role in meeting the complex needs of sectors in need of large format printing capabilities.

In the past, the word 'plotter' might have brought to mind a device equipped with pens that sketch on a paper roll. However, contemporary plotters have significantly advanced, adopting inkjet technology. These modern machines are essentially large format inkjet printers boasting various functionalities. They operate on the same fundamental principle of dispersing ink onto paper, but employ specialised ink cartridges and printheads to manage extensive print areas. This innovation enables current plotter printers to deliver high-resolution images, intricate drawings and clear text. Consequently, they have become essential tools to various sectors, including architecture, engineering, design and even fine art printing.

Numerous types of plotter printers are available in today's market, yet only one stands out as the preferred choice for contemporary working environments.
• Electrostatic plotters: They once held a prominent position, employing electrostatic charges to produce large-scale architectural drawings. Nevertheless, their usage has markedly diminished over the years due to the advent of advanced printing technologies.

• Pen plotters: They are a traditional method of computer-aided drafting, generating drawings by moving a pen across paper. These plotters use a system of motors and gears to guide the pen's movements, raising and lowering it to create lines, curves and shapes. However, they have lost prevalence as more modern printing solutions like large format inkjet plotters have emerged.

• Inkjet plotters: They have now become the industry benchmark. Most AEC, GIS or print shops possess at least one large format inkjet printer. These devices are known for their versatility, speed and ability to deliver prints with exceptional colour accuracy—fulfilling diverse printing needs, from intricate art and design work to the exacting standards required for technical applications.

Plotter printers, with their advanced capabilities, are meticulously engineered to meet the exacting standards of various professional applications. Each industry presents its unique set of challenges, and plotter printers are specifically designed to address these while delivering precision, efficiency and quality.

AEC (Architecture, Engineering and Construction)

Precision is the cornerstone of the AEC industry—the accuracy of architectural plans, engineering drawings and construction blueprints can make the difference between a successful project and a structural failure. Plotter printers, such as the HP DesignJet series, offer:
• High-resolution printing that ensures even the most subtle gradients and shades are visible—vital for conveying building design intent, visualising material finishes and facilitating stakeholder decision-making
• Compatibility with a range of CAD software, enabling a smooth transition from digital design to physical output
• Capability to create full-scale drawings on a single page, eliminating the need to piece small prints together, reducing the risk of misalignments and ensuring a comprehensive understanding of the project

GIS (Geographic Information System) mapping

GIS professionals work with complex data representing various geographical features and phenomena. The large format capability of plotter printers like the HP DesignJet series allows for the creation of expansive and detailed maps that can be used for urban planning, environmental conservation, resource management and emergency response planning.
• High-resolution, colour-accurate prints, crucial for distinguishing between different topographical elements and data overlays
• Printing on varied media—on more durable materials for field work or on high-quality paper for displays

Copy shops

Copy shops require printing solutions that are versatile, capable of high-volume output, reliable and easy to use. Plotter printers, such as the HP DesignJet series, cater to these needs by providing a range of services—from printing large promotional posters to producing intricate technical diagrams for local businesses.
• Easily switches between various media types and sizes, allowing copy shops to expand their offerings
• Speedy and efficient, enabling quick turnarounds, which is essential for meeting customer demands

As a dominant player in the print industry, HP’s plotter printers produce exceptional large format prints that cater to even the most demanding printing needs. Their user-friendly hardware design, powerful performance and extensive connectivity options make them the perfect solution for contemporary engineering workflows, ensuring smooth integration and maximum efficiency.

• Exceptional speed and efficiency: The HP DesignJet boasts an impressive print speed of up to 25 seconds for an A1 print and produces up to 81 D prints per hour. This exceptional speed ensures that projects are completed swiftly without compromising on quality.

• Reduced overall printing costs: The latest HP DesignJet T850 plotter printer uses efficient ink systems, such as HP's proprietary pigment inks, also known as HP Flex Tech inks. These inks offer high-quality prints with lower ink consumption, resulting in fewer ink replacements and lower overall printing costs.

• Sustainable practices: HP DesignJet printers are crafted with a focus on sustainability, utilising recycled components and minimising energy use. The HP DesignJet T650 is made with up to 30% UL-validated recycled plastic, which helps to cut CO2e emissions by as much as 7.3 tons annually.

• Adaptable to contemporary work environments: HP mobile printing, wireless capabilities and user-friendly software such as HP Click support its flawless integration with current workflows. HP Click streamlines large format printing, enabling users to print directly from numerous applications with a single click while accommodating various file formats.

HP DesignJet T250: The compact, large format plotter printer is designed to streamline workflows for businesses of all sizes. This model is HP's smallest plotter, making it ideal for environments with limited space. Despite its compact size, it boasts impressive printing capabilities, including a print speed of 30 seconds per A1/D plot and a resolution of up to 2400 × 1200 optimised dpi. Its user-friendly interface boosts productivity, without increasing your budget.

HP DesignJet T650: This plotter printer delivers a rapid print speed of 26 seconds per A1/D plot, significantly enhancing productivity. It accommodates both sheet and roll feed and includes an automatic sheet feeder, providing flexibility for diverse printing requirements.
