AI-generated summary
Canon’s 051H black toner is a sensible option if you’re printing a lot and want something that behaves like “set it and forget it” — consistent output, no fiddling, and generally low drama compared with cheaper third-party alternatives. At £85.66 ex-VAT for a high-yield cartridge, the real question is what you’re paying per page in practice: if your team’s running frequent, everyday mono printing (invoices, admin docs, reports), this will usually work out better than the standard-yield versions and tends to be the safer choice for maintaining steady print quality and fewer support headaches.
That said, I wouldn’t automatically buy it if your volumes are modest or sporadic. High-yield cartridges tie up cash and if usage is low you may be waiting longer for “value” to catch up. Also, if you’re already set up for genuine Canon consumables and your fleet is tuned around them, it’s a good fit; if you’re chasing lowest possible cost per page and you’re comfortable trialling alternatives, Canon genuine won’t be the bargain pick. Bottom line: buy it for steady mono printing and budget predictability; think twice if your output is irregular or you need the absolute cheapest per-page option.
