Choosing between HP 831, HP 871, and HP 873 latex ink comes down to two things: your exact HP Latex printer model and the cartridge format that model uses. This guide is a plain-English cross-reference to help you identify the right ink family before requesting a quote. All ink discussed here should be treated as compatible aftermarket replacement ink unless a quote specifically states OEM.
Quick comparison
| Ink family | Typical cartridge format | Commonly associated printers |
|---|---|---|
| HP 831 | 775 ml | HP Latex 360, 365 (300-series) |

| HP 873 | 3 liter | HP Latex 800, 800W, 830, 830W |
This table is a cross-reference guide only. Always confirm compatibility against your printer’s documentation and cartridge slots before ordering.
How to identify the right ink for your printer
Start with the exact model name printed on your HP Latex machine, then note whether it is a white-ink-capable W-series unit. The cartridge format (775 ml vs 3 liter) is the key differentiator between these families, and it is not interchangeable across formats even when the latex chemistry is comparable.
For model-specific guidance, see the HP Latex 360 and 365 ink guide.

HP Latex ink compatibility — frequently asked questions
What is the difference between HP 831, HP 871, and HP 873 ink?
HP 831, HP 871, and HP 873 are three related HP Latex ink families that differ mainly by cartridge format and the printer generations they are associated with. HP 831 is the 775 ml cartridge family associated with HP Latex 300-series machines such as the Latex 360 and 365. HP 871 is a 3-liter cartridge family associated with larger HP Latex 800-series and select 500-series configurations. HP 873 is a 3-liter latex ink family associated with HP Latex 800-series printers including 800, 800W, 830, and 830W. Always verify the exact printer model and cartridge format before ordering.
Are HP 831 and HP 871 interchangeable?
Not as a direct swap. Even where the underlying latex chemistry is comparable, the cartridge format and machine fit differ, so a printer built around 775 ml HP 831 cartridges is not automatically compatible with 3-liter HP 871 cartridges. Compatibility should always be confirmed for the specific printer model before ordering.
Which HP Latex printers use which ink family?
As a general reference, HP Latex 360 and 365 are commonly associated with HP 831 775 ml cartridges, HP Latex 800/830 configurations are commonly associated with HP 873 3-liter cartridges, and certain larger or intermediate configurations are associated with HP 871 3-liter cartridges. These are cross-reference guidelines only; the printer’s own documentation and cartridge slots are the final authority.
Do you sell original HP OEM ink or compatible replacement ink?
Unless a specific quote or listing states OEM, ink discussed here should be treated as compatible aftermarket replacement ink rather than original HP OEM ink. HP part numbers are used only as cross-reference identifiers so buyers can match cartridge family, color, and printer compatibility.
How do I get a quote for HP Latex ink?
Provide the printer model, whether it is a white-ink-capable W-series machine, the colors and quantity needed, current cartridge part numbers if available, and your shipping location. Pricing, availability, and lead time are quote-based and depend on configuration and supplier stock.
