AI-generated summary
If you’re looking at the Canon PG‑595 “original black” at **£15.88 ex‑VAT**, it’s a sensible buy **only if your printer model takes that specific cartridge** and you want clean, reliable prints without tinkering. Original Canon ink tends to be the least hassle in day-to-day office use—fewer surprises with print quality, fewer “why is it streaking?” moments, and generally more predictable results for things like letters, basic documents, and internal paperwork. For a small business that just needs to keep the printer working, this price is pretty fair.
That said, I’d be cautious if you print a lot. Ink cartridges can get expensive fast, and your total cost per page will usually look better with compatible cartridges or a different supply strategy—especially if you’re mostly producing text-heavy volumes. Also, if you don’t print frequently, there’s always the risk of ink drying out between uses, which can undermine value. Bottom line: **buy it if you’re a light-to-medium printer and you value reliability**. **Skip it if you’re cost-sensitive with high page counts** or you know you’ll go long gaps between prints.
