How to Calculate the Total Cost of Ownership for Meraki
28 Mar, 2026

£91.97 inc. VAT
AI-generated summary
If you’re running an Epson wide-format or commercial printer that actually supports the T9139, this cartridge is the sort of “set-and-forget” buy that makes sense. At ~£76 ex-VAT for a 200ml fill, it’s not a bargain-bin impulse purchase, but it’s priced like a genuine consumable where you’re paying for consistent output and fewer drama-inducing print issues than with mismatched third-party inks. For businesses doing regular prints (graphics, signage prep, CAD/GIS maps, proofing), reliability and predictable colour/black density usually outweigh the temptation to chase the cheapest per-ml option.
That said, I wouldn’t buy it if you’re not sure your printer model is compatible or if you rarely print—because any ink you leave sitting around is money tied up, and the real cost shows up when you’re trying to get stubborn nozzles back to life after downtime. Also, if you’re printing high volumes and you’re currently getting good results with an alternative supplier, compare *actual* cost per page/output rather than just the cartridge price. Overall: buy it if you’re an Epson-ecosystem user who values dependable black output and uptime; skip it if your usage is sporadic or compatibility isn’t absolutely confirmed.
