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.

The TC-21 has been designed differently.
