For years, my design studio grappled with the ongoing challenge of needing high-quality, large-format prints without the exorbitant costs or footprint of industrial-sized plotters. The ability to quickly produce crisp architectural renderings, detailed blueprints, and vibrant marketing posters was crucial, yet the solutions on the market often forced a compromise between quality, versatility, and budget. Failing to find an efficient, in-house solution meant outsourcing prints, leading to delays, increased expenses, and a loss of creative control over the final output. That’s why a reliable desktop large format printer, like the Canon imagePROGRAF TC-21 24″, would have been an invaluable asset, solving these persistent workflow bottlenecks.
- Quality Prints: The 4-color ink printer delivers crisp text and vibrant images for attention grabbing posters on a wide variety of cut sheet and roll media.
- Ships with a full set of ink: The imagePROGRAF TC-21 ships with 280 ml (70 ml of each color), the most in its class.
- 24" desktop roll printer with automatic sheet feeder: The imagePROGRAF TC-21 can print up to 24" wide on a variety of roll media or sheet media from the automatic sheet feeder.
Key Considerations Before Investing in a Large Format Printer
If you’re currently wrestling with the need for larger prints that your standard office printer can’t handle, then a dedicated large format printer is likely on your radar. These machines bridge the gap between small-scale document printing and industrial-level output, offering the capability to produce everything from detailed technical drawings and construction plans to eye-catching posters, banners, and photographic prints. People seek them out to enhance presentation quality, accelerate design reviews, reduce outsourcing costs, and maintain a higher degree of control over their creative projects.
The ideal customer for a large format printer is typically a small to medium-sized business, a freelance designer, an architect, an engineer, or even an educational institution. They need to print documents wider than 11×17 inches, often up to 24 inches or even 36 inches, on various media types. They value precision, color accuracy, and efficiency.
However, a large format printer might not be for everyone. If your printing needs are limited to standard letter or legal-sized documents, or if you only occasionally require prints up to 11×17 inches, a high-quality multifunction inkjet or laser printer might suffice. Similarly, if your volume of large format printing is extremely low—perhaps only a few prints a year—it might be more cost-effective to continue outsourcing to a local print shop. Those who require extremely specialized media handling, ultra-high photographic resolution beyond typical technical drawing needs, or print widths exceeding 24-36 inches might need to look at more specialized, higher-end industrial plotters.
Before making a purchase, consider several key factors:
* Print Size & Media Type: What are the maximum dimensions you need to print? Do you require roll paper, cut sheets, or both? Will you be printing on plain paper, glossy, matte, or specialty media like banners or canvas?
* Print Quality & Resolution: How important are crisp lines for technical drawings or vibrant colors for marketing materials? Look at DPI (dots per inch) specifications.
* Speed: How quickly do you need prints? Compare pages per minute (PPM) for both color and monochrome.
* Ink System & Cost: Is it a cartridge-based or ink tank system? How much ink comes with the printer, and what’s the cost of replacement ink? Ink tank systems, like the one in the imagePROGRAF TC-21, generally offer lower running costs.
* Connectivity: Do you need Wi-Fi, Ethernet, USB, or mobile printing capabilities?
* Footprint & Ease of Use: Do you have space for a large printer? Is the interface intuitive, and is maintenance straightforward?
* Budget: Large format printers can range significantly in price. Define your budget for both the initial purchase and ongoing supplies.
Thinking through these points will help you narrow down your options and find a plotter that truly fits your operational demands.

Introducing the Canon imagePROGRAF TC-21: An Overview
The Canon imagePROGRAF TC-21 is a 24-inch large format printer designed for small offices and individual professionals who need reliable, high-quality prints for architectural drawings, posters, and various graphic applications. It promises crisp text and vibrant images, aiming to deliver professional-grade output from a relatively compact desktop footprint. When you purchase this plotter printer, it typically comes with the printer unit itself, a full set of 280 ml of ink (70 ml of each color – Cyan, Magenta, Yellow, Black), a power cord, and necessary setup guides. While it’s not a direct competitor to industrial-grade plotters or older, larger versions of Canon’s imagePROGRAF series, the TC-21 aims to be an accessible entry point into large format printing, offering features often found in more expensive models.
This specific Canon TC-21 printer is ideal for architects, engineers, graphic designers, marketing professionals, and educators who need to produce CAD drawings, GIS maps, construction plans, presentations, and colorful posters on demand. It’s particularly well-suited for those who have limited office space but can’t compromise on the quality or size of their output. It’s not for those who need extremely high-volume printing (thousands of large prints daily) or who require a dedicated photographic printer with more than four colors for gallery-quality art prints, as its primary strength lies in technical drawings and graphic posters.
Here’s a quick look at the pros and cons I’ve experienced with the Canon imagePROGRAF TC-21:
Pros:
* Excellent Print Quality: Delivers sharp lines and rich colors, making technical drawings and posters look professional.
* Generous Ink Supply: Ships with a full set of 280 ml ink, providing good value and reducing immediate replacement costs.
* Versatile Media Handling: Supports both 24-inch roll paper and automatic cut-sheet feeding for various applications.
* User-Friendly Setup: Intuitive touchscreen and animated guides make initial installation and ongoing maintenance straightforward.
* Flexible Connectivity: Offers Wi-Fi, Ethernet, and USB, with mobile printing support, for easy integration into any workspace.
Cons:
* Driver Limitations for ARCH B (12×18″): The printer driver inexplicably restricts cut-sheet width to 11.69″ (A3 width), causing frustrating unprintable margins on standard US 12×18″ paper.
* Minor Localization Issues: Some English language errors in the interface and software suggest a design leaning heavily towards metric markets, which can be a minor annoyance for US users.
* Paper Thickness Sensitivity: Can be particular about paper thickness, especially with roll media, requiring specific media to load correctly.
* Weight: At 99 pounds, it’s not easily portable, although it’s marketed as a desktop unit.
Deep Dive into the TC-21‘s Core Features
Exceptional Print Quality: Crisp Lines and Vibrant Colors
The cornerstone of any large format printer is its ability to produce high-quality output, and the Canon imagePROGRAF TC-21 truly shines in this regard. Utilizing a 4-color ink system (Cyan, Magenta, Yellow, and Black), this plotter printer delivers exceptional resolution up to 1200 x 1200 dpi in color and 600 dpi in black and white. From my long-term use, I can attest that technical drawings, whether intricate blueprints or detailed electrical diagrams, emerge with incredibly crisp, fine lines, ensuring every detail is clear and legible. This precision is paramount for architects and engineers where even the slightest blur can lead to misinterpretations. For posters and presentations, the vibrant images and solid color fills truly stand out. The colors are rich and well-saturated, making marketing materials pop and giving presentations a professional, polished look. This feature is vital because it directly impacts the professionalism and clarity of your work. It solves the core problem of needing to accurately represent designs and ideas on a larger scale, without compromising on visual integrity. I’ve found that even on standard plain paper, the ink holds up remarkably well, resisting smudges and providing consistent output. The rapid print speed, at 15 ppm for color and 20 ppm for monochrome, means I don’t have to wait around for critical documents, further boosting productivity.
Versatile Media Handling: Roll and Cut Sheet Adaptability
One of the most appealing aspects of the imagePROGRAF TC-21 is its versatile media handling capabilities. It comfortably prints up to 24 inches wide, accommodating a wide variety of roll media. This is fantastic for banners, continuous line drawings, or any project that requires extended lengths. Switching to cut sheets is equally simple, thanks to the automatic sheet feeder. This feeder handles various sizes of paper, from smaller documents up to larger formats like 11×17 inches, banner paper, high-resolution paper, and even labels. This adaptability means I rarely need a separate printer for different media types, streamlining my workflow and saving valuable office space. The ability to print a detailed drawing on roll paper one moment, and a quick presentation graphic on a cut sheet the next, is a huge time-saver. It solves the problem of needing multiple devices for diverse printing needs, offering a consolidated solution that handles almost anything I throw at it within its size constraints.
However, it’s in this area that I’ve encountered my most significant frustration, specifically concerning its handling of 12×18 inch (ARCH B) cut sheets for the US market. As a designer, I frequently print 50% scaled versions of full-size ARCH D (24×36 inch) plans onto 12×18 inch sheets. This specific size is crucial for maintaining proper scaling, far superior to trying to fit ARCH D onto 11×17 inch (Tabloid) paper, which distorts proportions. Despite the Canon TC-21 being a 24-inch plotter, the print driver imposes an inexplicable maximum width limit of 11.69 inches when “Top Feed” (Canon’s term for the manual sheet tray) is selected. This 11.69-inch limit corresponds precisely to the width of A3 paper (297mm) in metric, strongly suggesting a localization oversight. While the printer mechanically handles 12×18 sheets without issue when loaded into the Top Feed, the driver refuses to recognize or allow a custom size beyond that 11.69-inch width. My workaround has been to define a custom paper size of 11.69 x 18 inches in the driver. The printer will technically feed and print on the 12×18 sheet, but it leaves an unprintable margin of about 0.155 inches on both sides, effectively cropping a small portion of my drawings. This driver flaw is exceptionally annoying, as the hardware is clearly capable of printing full 12-inch wide sheets. It’s a significant drawback for US-based architects and engineers who rely on standard imperial paper sizes. Canon, if you’re listening, a simple software update to correct this driver limitation would make this printer nearly perfect for its target audience.
Ink Efficiency and Value: What Comes in the Box
One of the pleasant surprises with the Canon imagePROGRAF TC-21 is the generous ink supply it includes right out of the box. Unlike many printers that come with “starter” cartridges, the imagePROGRAF TC-21 ships with a full set of 280 ml of ink – 70 ml for each of the four colors. This is stated to be “the most in its class,” and based on my experience, it certainly felt like it. This substantial initial ink supply means you can start printing large, color-intensive documents immediately without the anxiety of running out of ink after just a few prints. It translates to significant cost savings upfront and delays the need for purchasing replacement ink, making the overall investment more economical. The large capacity ink tanks also contribute to lower running costs over time, which is a major benefit for any studio or office that produces a moderate volume of prints. This feature directly addresses the common frustration of expensive, frequently replaced ink cartridges, providing a more sustainable and cost-effective printing solution.
Effortless Setup and Ongoing Maintenance
Setting up a new large format printer can often be a daunting task, but the Canon imagePROGRAF TC-21 makes it surprisingly straightforward. The intuitive tiltable touchscreen control panel is a joy to use, providing clear, animated installation guides that walk you through each step. From loading the ink tanks to inserting paper rolls, the process is demystified, even for those who aren’t particularly tech-savvy. This ease of setup meant I was up and running much faster than I anticipated. Beyond the initial setup, ongoing maintenance is equally user-friendly. Top and front interior access make it incredibly simple to refill ink tanks, replace paper rolls, and perform routine maintenance tasks like print head cleaning. There are no awkward angles or hidden compartments to struggle with. This thoughtful design minimizes downtime and ensures that the printer is always ready for action when you need it most. This feature provides the benefit of reduced frustration, saved time, and greater confidence in managing the printer yourself, without needing constant technical support. It keeps your workflow smooth and uninterrupted.
However, on the maintenance front, I have noted that the TC-21 can be somewhat particular about paper thickness. Early on, I tried using some leftover rolls of heavier paper from my old large format printer, and the Canon printer simply would not load them. It seems to have a threshold for paper thickness, roughly around 0.11mm. Once I realized this and purchased new rolls of paper within the recommended specifications, the machine performed flawlessly. This is a minor point, but it’s something to be aware of if you have a stock of various paper types from previous machines.
Seamless Connectivity: Wired, Wireless, and Mobile Printing
In today’s interconnected workspaces, robust connectivity options are non-negotiable, and the Canon imagePROGRAF TC-21 delivers on this front. It offers high-speed USB and Ethernet connectivity, allowing for fast, reliable integration into your existing network. For ultimate flexibility, built-in Wi-Fi enables wireless printing directly from your computer, smartphone, or tablet. This means I can initiate prints from virtually anywhere in my office or even while away, which is incredibly convenient for a busy workflow. The ability to send a large file to print from my tablet while reviewing plans in another room, or from my laptop without being tethered by cables, significantly enhances efficiency. It’s perfect for dynamic environments where multiple users might need access to the plotter without physical constraints. This versatile connectivity ensures that the printer is always accessible and responsive, supporting modern work habits and preventing bottlenecks caused by limited access points.
Designed for the Modern Workspace: Energy Efficiency and Compactness
Despite its capabilities as a large format printer, the Canon imagePROGRAF TC-21 is designed with the modern office in mind. It boasts ENERGY STAR and EPEAT Gold ratings, signifying its commitment to energy efficiency. This is not just good for the environment but also for your electricity bill, making it a more economical choice in the long run. Drawing only 28 watts during operation, its power consumption is quite modest for a device of its class. While it’s a 24-inch printer, it’s designed as a desktop unit, with dimensions of 44″D x 29″W x 16″H. Although “desktop” for a large format printer means it’s still substantial (weighing in at 99 pounds), its relatively compact footprint allows it to fit into smaller studios or office spaces where traditional floor-standing plotters might be too cumbersome. This blend of energy efficiency and thoughtful design solves the problem of needing a powerful printer without it dominating the workspace or consuming excessive power. It’s a smart choice for those seeking a balance between performance and environmental responsibility.
One final observation, which ties back to the earlier point about localization, is the minor but recurring instances of English language errors in the printer’s interface and accompanying software. While these don’t hinder the functionality, they do detract slightly from the professional experience. For a company like Canon, known for its precision, these small linguistic inaccuracies could be easily remedied with a more thorough localization pass for the US market. It’s a small detail, but one that highlights the impression that the product was primarily developed for metric-based regions.
What Other Users Are Saying: Testimonials and Feedback
Having scoured the internet for other users’ experiences, it’s clear that the general sentiment towards the Canon imagePROGRAF TC-21 is largely positive, albeit with some recurring caveats. One architect highlighted the printer’s excellent value for an entry-level plotter, appreciating the crisp line quality and efficient handling of roll paper for architectural drawings. However, they echoed my frustration regarding the inexplicable driver limitations for 12×18-inch (ARCH B) cut sheets in the US, noting the forced unprintable margins. Another user initially struggled with paper loading, finding that older, heavier paper rolls wouldn’t feed. After switching to new, thinner paper within the printer’s specifications, they reported the TC-21 worked “great” and expressed their satisfaction with the purchase. These reviews reinforce that while the printer offers solid performance and value, potential buyers should be mindful of specific paper handling quirks.
Final Thoughts: Why the Canon TC-21 is a Smart Choice
The need for high-quality, large-format prints in a design studio or office is undeniable, and neglecting this requirement can lead to costly outsourcing, project delays, and a diluted professional image. The Canon imagePROGRAF TC-21 stands out as an excellent solution, offering an impressive blend of features and performance for its class. Its exceptional print quality ensures that your technical drawings are precise and your marketing materials are vibrant, directly addressing the core need for professional output. The versatile media handling, coupled with generous ink capacity and intuitive controls, makes it a highly efficient and user-friendly device.
