HP Jetdirect 510X Print Server Ethernet - Share Multiple Printers

In this review the HP Jetdirect 510X is presented as a straightforward solution for small offices and workgroups that need to share multiple parallel printers over a wired network. The bottom line: this external print server makes it simple to connect up to three legacy parallel printers to a single 10/100 Ethernet link, providing reliable 100 Mbps network printing without complicated setup. It is best for environments that rely on older IEEE 1284 printers but still require modern TCP/IP interoperability and basic remote management.

Key Features

• Triple parallel ports: Three IEEE 1284 parallel connections let existing printers remain in service while sharing one network connection, avoiding costly printer upgrades.
• 10/100 Ethernet: The 1 x RJ-45 Ethernet port supports 10Base-T and 100Base-TX for fast, stable network transfers at up to 100 Mbps.
• Wide protocol support: Built-in support for TCP/IP, IPX/SPX, AppleTalk and DLC/LLC helps the device integrate with mixed network environments.
• Simple external form factor: As an external unit it installs without internal modifications to printers, keeping deployment quick and noninvasive.
• Remote management compatibility: IPP and standard management protocols allow administrators to configure and monitor the unit over the network.

Who It's For

This print server suits small offices, labs, or production floors that still use older parallel printers and cannot or prefer not to replace them. IT teams who need to centralize printer access across workstations and maintain legacy devices will find the HP Jetdirect 510X particularly useful.

It is less appropriate for users who already have network-ready printers with native Ethernet, or environments that require wireless connectivity, gigabit speeds, or modern USB-only printers. Those users should look for a network adapter that matches newer interface standards.

Pros & Cons

Pros

• Allows three parallel printers to be shared over a single wired Ethernet connection, extending the life of existing hardware.
• Supports common network protocols such as TCP/IP and IPP for broad compatibility on mixed networks.
• External design makes installation and replacement straightforward without opening printer chassis.

Cons

• Limited to wired 10/100 Mbps Ethernet and parallel printer interfaces, so it will not support USB-only or wireless printing without additional adapters.

Specifications

Our Verdict

The HP Jetdirect 510X is a pragmatic choice for organizations that need to network multiple legacy parallel printers without replacing them. Its reliable 10/100 Ethernet connectivity, broad protocol support, and external form factor deliver straightforward value for IT teams maintaining older fleets. If you need wireless support, gigabit speeds or USB-only printer compatibility, consider a more modern adapter instead.

Frequently Asked Questions

Can this server connect USB printers?
No. The Jetdirect 510X provides three IEEE 1284 parallel ports; USB-only printers are not supported without an intermediate converter.

Does it work with modern network protocols?
Yes. It supports TCP/IP and IPP along with legacy protocols like IPX/SPX and AppleTalk for mixed environments.

Is installation complicated?
Installation is generally straightforward since the unit is external and connects with standard Ethernet cabling and parallel printer cables.
