Compact Professional A1 CAD, Technical Drawing & Poster Desktop Printer

Professional A1 Printing Without the Size or Cost of a Traditional Plotter

The Canon imagePROGRAF TC-21 is a compact professional A1 printer designed for businesses that need occasional high-quality large-format printing without the footprint or cost of a traditional floor-standing plotter.

Ideal for architects, engineers, construction professionals, surveyors, schools, retailers and small offices, it produces crisp CAD drawings, technical documents, planning applications and vibrant posters up to 24 inches (610mm) wide.

With refillable ink bottles, straightforward operation and Canon’s proven imagePROGRAF print technology, the TC-21 offers an affordable way to bring professional A1 printing in-house.

If you’re printing occasionally or a few times each week, it’s an excellent choice. If you’re producing larger volumes every day, one of Canon’s TM Series printers may offer a lower long-term cost of ownership thanks to larger ink capacities and higher productivity.

The TC-21 is firmly pitched at infrequent use, if you need the odd A1 poster, then its ideal, unlike other options there is a narrower range of medias as it only accepts 2-inch core paper, we reccomend Canon 190gsm Satin Paper for posters, or CAD Plot 140gsm, and 180gsm Matte.

Compact Design That Fits Almost Anywhere

Many wide-format printers demand valuable office space.

The TC-21 has been designed differently.

Its compact footprint makes it suitable for desks, studios, classrooms and smaller offices where space is at a premium.

Optional accessories, including a floor stand and print basket, a unique desk basket, allow the printer to grow alongside your business as requirements change.

The Canon TC-21 uses refillable 70ml ink bottles instead of conventional cartridges.

Benefits include:

Approximately 280ml of starter ink is included in the box, allowing you to begin printing immediately.

If your business expects to print throughout the day or produce higher weekly volumes, it’s worth considering the Canon TM Series. Although the initial purchase price is higher, larger ink capacities can deliver a lower total cost of ownership over the life of the printer.
