Large format printer Canon imagePROGRAF TC-21 Inkjet Wi‑Fi Colour 2400 x 1200 DPI A1

The Canon imagePROGRAF TC-21 is a compact large-format inkjet printer designed for homes and small offices that need A1 prints with professional quality. It supports both roll and cut media, produces four-colour output (Black, Cyan, Magenta, Yellow) at up to 2400 x 1200 DPI, and offers multiple connectivity options including Wi‑Fi, Ethernet and USB. The printer combines a small footprint with sustainable design choices, making it suitable for architecture, engineering and construction (AEC) workflows, retail materials and general office signage.

Advantages

This model delivers high-resolution prints with pigment inks and advanced image processing for denser colours and sharper detail. The hybrid media support and built-in auto-sheet feeder let you switch between rolls and cut sheets without manual intervention, saving setup time. A shaftless roll holder and an adjustable operation panel simplify media loading and monitoring. Energy-efficient design, reduced operating noise, recyclable ink bottles and the use of recycled plastics contribute to lower environmental impact.

Suitable for

• Printing CAD drawings and technical plans in A1 format
• Producing posters, banners and marketing collateral in various sizes
• Small office and home office printing where space is limited
• Schools, hospitality and retail shops needing on-demand signage

When it may not be suitable

The TC-21 is optimized for small workspaces and moderate print volumes; it may not meet the throughput or media handling requirements of large production print environments. It is a four-colour device, so workflows that require extended colour gamuts or light-colour inks for photographic proofing may need a different model.

How to use

Install the printer on a stable surface and follow the guided roll-setting procedure to load roll media or use the auto-sheet feeder for cut sheets. Connect via Wi‑Fi, Ethernet or USB and install the Canon job submission tools and drivers to enable features like Direct Print Plus and Free Layout Plus. Use the tiltable control panel to monitor job status and adjust settings. For mixed workflows, set media type and size in the driver before printing to ensure correct margins and colour handling.

What to consider before purchase

• Intended print volume and whether a compact desktop device meets your throughput needs
• Need for four-colour printing versus models with expanded colour sets
• Available space for roll handling and access to the auto-sheet feeder
• Compatibility with your existing software and whether shared job submission tools are required

Usage recommendations

For best results with CAD drawings and posters, use ISO A-series media up to A1, select the appropriate media profile in the driver, and keep pigment ink bottles topped up to maintain consistent colour density. Use the hybrid support to separate home and office workflows while sharing compatible Canon software tools.
