Product Identity

The HP 8FP31A is a Jetdirect LAN adapter designed to add wired network connectivity to compatible HP printers and multifunction devices. It installs internally to provide a standard Ethernet interface for office environments.

Fit and Alternatives

This accessory suits administrators who need to integrate supported HP imaging hardware into an existing wired LAN infrastructure. It is not for users whose printer lacks the appropriate internal slot, for those requiring wireless connectivity, or for buyers seeking a standalone external print server.

Deciding Specification

The defining attribute is the HP Jetdirect LAN Accessory form factor, which determines whether the adapter physically and electrically matches the target device. Verify the printer’s service documentation for the exact accessory slot before purchasing.

Questions about this item

Should I choose the 8FP31A adapter or another part number for my HP printer?

Select the 8FP31A when your printer documentation lists this exact part number; other Jetdirect accessories carry different model codes and will not fit the same slot.

What does the HP Jetdirect LAN Accessory actually do once installed?

It adds a wired network port so the printer can join a LAN and accept print jobs from any computer on that network without a direct USB cable.

Which network standard does the 8FP31A use and what speed does it support?

The adapter connects through the printer's internal accessory interface and provides a standard Ethernet link; the achievable throughput follows the printer's own network stack.
