The Canon imagePROGRAF PRO-4000S is a professional large-format inkjet printer with a 44-inch (A0+, 1,117mm) print width and an 8-colour ink system, built for photo printing, proofing, fine art reproduction, and poster production. The "S" designation in Canon's PRO-4000S typically indicates a version without a built-in cutter/take-up unit compared to the standard PRO-4000, trading a small amount of finishing convenience for a lower price point. This class of printer is aimed at photography studios, fine-art print shops, and design/proofing houses needing museum-quality large-format colour output, not general office or basic signage printing.
