HP 738M 300-ml Magenta DesignJet Ink Cartridge print head Thermal inkjet

Product Overview

AI-generated summary

Honestly, at **£169.88 ex-VAT** this feels like one of those “you’ll pay for convenience and reliability” ink setups rather than something that screams value. If you’re running a **HP DesignJet that actually takes this cartridge/inkhead combo**, it’s usually a safe choice because HP’s thermal inkjet consumables tend to behave consistently—good for offices that care more about predictable output than tinkering. You’ll typically like it if your team prints engineering/technical docs on a regular cadence and can’t afford random banding or frequent service interruptions.

That said, I wouldn’t buy this if you’re cost-sensitive or only print occasionally. For sporadic use, ink can be an expensive way to “keep the machine alive,” and you may end up paying premium pricing for something that won’t get fully used before the next job cycle. Also, if you’re not 100% sure the cartridge is the right match for your specific DesignJet model (or if your printer is already showing print quality issues unrelated to ink), it’s better to sanity-check compatibility first—wasting £170 on the wrong thing is painful.

**Who should buy:** businesses with ongoing DesignJet printing, who want dependable quality and minimal hassle. **Who should think twice:** one-off/low-volume print shops, and anyone trying to squeeze costs without validating exactly what their printer needs.
