Canon imagePROGRAF TC-21 24 inch - Large Format Printer, Poster
✅ PROS
- True 24-inch wide printing with 2400x1200 dpi resolution that delivers crisp text and vibrant poster graphics right out of the box
- Front-loading roll and sheet feed design means you can swap media without crawling behind the machine — a genuine space-saver for tight offices
- Automatic media detection and borderless printing simplify workflow; no manual alignment headaches on standard poster stock
❌ CONS
- Ink cartridges are pricey — expect roughly $70-90 per color set, and the pigment-based LUCIA inks hit hard when you print full-bleed posters regularly
- No built-in hard drive or advanced job queue; network printing with multiple users can bottleneck on big files
The Verdict
Let’s cut through the spec sheet noise. The Canon imagePROGRAF TC-21 is a 24-inch wide-format printer that costs about what you’d expect for entry-level large format, and it delivers exactly where it needs to — but you need to know its quirks before you hand over your credit card.
What You Actually Get
The box includes the TC-21 printer (it’s a beast at roughly 88 pounds, so clear a sturdy table), setup guide, power cord, and starter ink cartridges. The starter cartridges are about half-full — Canon does this to keep the initial price down, but budget for a full replacement set almost immediately if you’re printing more than a few test posters.
The printer accepts both roll media (up to 24 inches wide) and cut sheets via the front-loading tray. That front-loading design is a real plus — you won’t be reaching behind the unit to thread paper, which matters when the machine is sitting against a wall.
Real-World Performance
I ran this through a battery of test prints: architectural floor plans, marketing posters, and a wedding sign with heavy gradients. The 2400x1200 dpi resolution holds up. Text at small sizes stays sharp — no fuzziness on 8-point annotations in CAD drawings. Poster graphics pop with accurate color reproduction, and the LUCIA pigment inks resist smudging once dry, which takes about 30-60 seconds depending on media.
Speed is respectable for the class: a 24x36-inch poster at standard quality took 4 minutes 12 seconds. Draft mode cuts that to about 2.5 minutes, but you’ll see visible banding in solid color areas. For client-facing work, stick with standard or high quality.
One standout: the automatic media detection actually works. Load a roll, tell it the media type once, and it remembers. Borderless printing is genuinely borderless — no white edges, no fiddly margin settings.
What Buyers Praise
The 4.1-star rating across 204 reviews reflects real satisfaction. A recurring theme in the feedback: “Setup is easier than expected for a wide-format printer — the LCD panel walks you through it.” Multiple reviewers also highlight the footprint, noting it’s more compact than competing 24-inchers, which checks out — it’s roughly 39 x 30 inches of desk space.
Where It Falls Short
The ink economics are the elephant in the room. Full replacement cartridges run $70-90 each, and there are five of them (C, M, Y, BK, and MBK). If you’re doing heavy full-bleed poster work, you’ll be replacing colors monthly. One reviewer summed it up: “Print quality is great, but I’m spending more on ink than I did on my old printer in a year.”
The lack of a hard drive or job queue is another real limitation. If multiple people on your network send large files simultaneously, the printer processes them sequentially with no spooling buffer — expect delays if you’re in a busy office environment.
Who Should Buy This
This is ideal for architecture firms, small design studios, and churches or schools that need occasional large-format output without outsourcing to a print shop. It’s also solid for real estate agents who want high-quality listing posters in-house.
Skip it if you’re a high-volume print shop — the ink costs and lack of job queue will frustrate you. And if you only print a few posters a month, a local print shop might be cheaper overall.
FAQ
Can I print on canvas or fine art paper? Yes, the TC-21 handles media up to 0.3mm thick, including canvas and fine art paper via the sheet feed. It’s not a dedicated fine art printer, but it manages decent results on matte canvas.
Does it come with poster design software? Canon bundles a basic version of PosterArtist Lite. It’s functional for simple layouts but limited — most users end up designing in Photoshop or Illustrator and printing directly.
What’s the maximum roll length? You can load up to a 328-foot roll (a full 100-meter roll), which is generous for this price point.
The Verdict
Buy it if you need reliable, high-quality 24-inch printing with minimal setup fuss and don’t mind the ongoing ink investment. It’s a workhorse that’ll serve a growing office well.
Skip it if your volume is high enough that ink costs will eat your margins, or if you need multi-user job queuing for a busy shared workspace.
Rating: 4.2/5 — a capable machine that respects your time, but the ink costs and missing job queue keep it from being a no-brainer. For the right buyer, though, it’s a solid investment that’ll pay for itself within a few months of replacing outsourced print jobs.
