The HP OfficeJet Pro K550 (also searched as HP K550 or C8157A) is a workhorse designed for fast, cost-effective business printing. It’s valued for sharp text, solid color graphics and the ability to handle higher volumes without constant downtime.

HP 88 XL system: ink cartridges and printheads working together

This model uses the HP 88 / HP 88 XL family, where the printer relies on both ink cartridges and printheads. Choosing the right components means cleaner lines, consistent color, and fewer interruptions. Our range of ink for HP OfficeJet Pro K550 is ideal for:

• Everyday office documents – crisp black text and clear charts
• Invoices, forms, shipping labels – dependable output page after page
• Color graphics – balanced CMYK colors for presentations and reports
• Higher-volume printing – especially with XL capacity cartridges

If you print frequently, consider XL options—they reduce replacement frequency and help keep the cost per page under control. And if you notice missing lines or uneven colors, it may not be the cartridge alone: the printhead can also be the key to restoring perfect print quality.

Printheads for HP K550: when ink isn’t the only issue
