Original vs compatible Epson 603XL ink

Original HP cartridges are manufactured by HP and typically cost £70.40 or more for the XL multipack. They are guaranteed to work and HP provides direct support if you have issues.

Compatible cartridges are manufactured by third-party companies to the same specifications as the HP original. They use the same ink chemistry and produce the same print quality in normal use. Quality varies by manufacturer — the retailers compared on this page all offer satisfaction guarantees.

Does using compatible ink void my warranty? No. Under UK and EU consumer law, using compatible cartridges cannot void your HP printer warranty. This right has been upheld by the courts and HP cannot legally require you to use only their own branded ink.

What is the difference between Epson 603 and 603XL?
The Epson 603XL is the high-capacity version. The XL black cartridge prints approximately 500 pages versus 150 pages for the standard Epson 603 black. The XL version costs more upfront but is considerably cheaper per page.
Why is Epson 603XL compatible ink so much cheaper?

No. Under UK consumer law, using compatible ink cartridges does not void your Epson printer warranty. Epson cannot legally require you to use only their own cartridges.

The Epson 603XL multipack includes four cartridges: one high-capacity black, one cyan, one magenta, and one yellow. This is the standard four-colour set needed for all compatible Epson Expression Home and WorkForce printers.
