Canon imagePROGRAF TC-21 24-Inch Large Format Printer (7055C002) – Roll and Auto Sheet Feed, Wi-Fi

The Canon imagePROGRAF TC-21 is a 24-inch desktop large format printer for architects, engineers, schools, and small businesses. It prints from roll media up to A1 size and from a built-in automatic sheet feeder for A4 and A3, using four pigment inks supplied in refillable 70 ml bottles.

Deep-Dive Story & Problem/Solution

Outsourcing Large Prints Adds Cost and Delay to Every Revision

Small design offices and schools send plans and posters to print shops, then wait a day for each revised drawing. Buying a full-size plotter has usually meant a large stand and a second printer for everyday pages.

The TC-21 sits on a desk and handles both jobs. It prints 24-inch rolls for CAD drawings and posters and feeds up to 100 A4 or 50 A3 cut sheets automatically.

All four inks are pigment-based, so lines stay sharp and prints resist water and highlighter marks on site.

Fast, Precise Line Work

Resolution of up to 2400 x 1200 dpi renders fine lines and small text, and an A1 drawing prints in about 30 seconds in draft mode.

Simple Operation

A top-loading roll, front control panel, and refillable ink tanks keep routine tasks straightforward. Free poster software helps non-designers create signage.
