Canon imagePROGRAF TC-21M – 24" Large Format Multifunction Printer

The imagePROGRAF TC-21M is a 24-inch large format multifunction printer designed for workspaces that need big prints without complicated setups. It bridges standard office paperwork and wide-format output by combining full 24-inch printing capability with everyday scanning and copying tools.

A standout capability is the onboard enlarge copy feature. Using the built-in letter flatbed scanner, you can take a standard small original and blow it up into a large-format print in just a few steps. It also supports walk-up tasks via a USB flash drive port, letting you plug in a drive and output documents without going through a computer. Everyday control is handled through a 2.7-inch tiltable touchscreen LCD, alongside direct cloud printing and scanning tools built into the interface.

For standard multi-page workflows, the auto sheet feeder holds up to 100 sheets of letter-size paper or up to 50 sheets of 11 x 17-inch media. The primary design limit to keep in mind is that the physical scanner bed is letter-sized, so direct copying is limited to documents that fit on a standard flatbed. In addition, the listing focuses on core handling and does not detail ink types or print resolution limits.

Verdict: The TC-21M is a practical fit for offices, studios, or job sites needing simple 24-inch printing combined with letter-sized enlargement copying. If you want direct USB, cloud, and auto-fed paper flexibility in one machine, it offers strong daily utility.
