Canon imagePROGRAF TC-21M large format printer Wi-Fi Inkjet Colour 2400 x 1200 DPI A1 (594 x 841 mm) Ethernet LAN

The Canon imagePROGRAF TC-21M is a compact 24-inch large-format inkjet printer with an integrated A4 flatbed scanner designed for small offices and workspaces that need professional-quality A1 prints. It produces colour output using pigment inks at a maximum print resolution of 2400 x 1200 DPI, accepts cut sheets and a roll, and supports common paper types including photo paper, plain paper and envelopes. Connectivity options include Wi‑Fi, Ethernet LAN, USB Type‑A and Type‑B, and mobile printing via Apple AirPrint and Mopria Print Service. Built-in features such as a shaftless roll holder, tiltable operation panel and 1 GB internal storage help streamline production of CAD drawings, posters, labels and other large-format materials.

Advantages

The TC-21M combines large-format printing and an A4 flatbed scanner in a compact desktop footprint, enabling scanning, copying, enlargement and repeat printing without requiring separate devices. High-resolution pigment ink printing and advanced image processing deliver dense colours and sharp details suitable for technical drawings and marketing collateral. Its simplified media handling — roll and cut-sheet support, auto-sheet feeder and USB direct printing — reduces setup and intervention. The model also integrates energy-efficient design and recycled materials to support sustainability goals.

Suitable for

• Architecture, engineering and construction (AEC) firms producing CAD drawings and blueprints
• Retail and hospitality locations needing on-site posters, banners and signage
• Small offices and schools requiring occasional large-format prints and scans
• Graphic designers and print studios producing proofs, posters and labels at A1/A2/A3 sizes

When it may not be suitable

The TC-21M is optimised for small to medium print volumes and compact workspaces; it may not be the best choice for high-volume production environments that require larger roll capacities or industrial throughput. Organisations that need integrated scanning larger than A4 or very specialised media types beyond standard cut sheets and rolls should evaluate alternatives that offer larger flatbed scanners or wider media handling.

How to use

Install the TC-21M on a stable desktop surface and connect it to power and your local network or directly to a workstation via USB. Load media using the shaftless roll holder for roll printing or the auto-sheet feeder for cut sheets, and select the appropriate media type and size on the tiltable operation panel. Use the built-in flatbed scanner for A4 originals to scan, enlarge or repeat images; scanned data can be saved to internal storage or transferred to a connected computer. For mobile or on-site printing, send jobs via Wi‑Fi using Apple AirPrint or Mopria, or print directly from a USB memory device. Regularly check ink levels and use the supplied pigment ink bottles to maintain print quality.

What to consider before purchase

• Required maximum print size (up to A1) and whether A1 output meets your project needs
• Typical monthly print volume — TC-21M is suited to low-to-moderate volumes rather than continuous industrial production
• Need for scanning larger than A4; built-in scanner is limited to A4 originals
• Supported media types and roll capacity relative to expected job sizes
• Connectivity and mobile printing requirements (Wi‑Fi, Ethernet, USB, AirPrint, Mopria)

Usage recommendations

For best results, use Canon-recommended pigment inks and paper profiles, verify media settings on the operation panel before each job, and perform routine maintenance checks. When producing posters or technical plans, print a test section at the intended scale to confirm colour density and line clarity, and trim margins as needed for final presentation.
