Canon i-SENSYS MF667Cdw all-in-one printer, colour laser, A4, fax, Wi-Fi

A laser printer fuses toner onto the paper with heat, so the page is dry immediately and the text will not smudge even if you pick it up at once or run a highlighter over it. Colour laser suits reports, presentations and proposals with charts and logos, and it handles ordinary text documents too. The maximum paper size is A4.

Alongside printing, the machine has a colour scanner and a fax. Signed contracts, stamped documents and colour attachments reach the digital archive looking like the original. Fax remains necessary for organisations and partners that still rely on it, and there is no need to keep a separate fax machine on the desk.

The MF667Cdw supports two-sided printing. Multi-page documents get thinner, paper use goes down, and folders and bound copies are more compact. In an office printing contracts, manuals and meeting packs, it is the feature used more than any other. A ream of paper lasts longer and the tray needs refilling less often.

The printer connects over Wi-Fi, so it can sit wherever there is room in the office rather than next to one computer. Every computer on the same network can print to it. The white and black housing fits a typical office. The manufacturer gives no information about wired interfaces.

Small and mid-sized offices that need colour laser printing, a scanner and a fax in one device; sales and marketing teams printing colour proposals and presentations; and organisations whose partners still send faxes. All of this is combined in one white and black unit that connects over Wi-Fi.
