AI-generated summary
If you’ve got a compatible Brother laser printer and you specifically want the original cyan cartridge, the TN-423C is the “no drama” option. Original toners usually give you consistent colour, good print stability over time, and predictable page yields—things you’ll care about in an office where you’re not troubleshooting faded bands or odd streaking mid-week. At **£133.13 ex‑VAT**, though, it’s not cheap, so it only makes sense if you genuinely print enough cyan to justify the spend and you care about quality consistency more than squeezing the absolute lowest cost.
I’d think twice if you’re a low-volume user or you’re cost-focused and okay with performance variability—after all, cyan is often the first colour to feel expensive when you don’t print regularly. If you can switch to higher-yield options or a better-value supply route (multi-packs, compatible alternatives, or a managed print approach), that’s where you’ll usually win value in the UK B2B world. But for departments running Brother devices day-to-day and needing reliable output for customer-facing documents, memos, or marketing print, this is a sensible, safe purchase.
