HP Jetdirect 620n J7934G 10/100TX Fast Ethernet EIO Print Server Card

HP Jetdirect 620n J7934G 10/100TX Fast Ethernet EIO Print Server Card

The HP Jetdirect 620n is a Fast Ethernet print server card that slides directly into a compatible HP printer's EIO (Enhanced Input/Output) slot, connecting the printer to a 10/100TX wired Ethernet network without the need for an external print server device. The card installs in seconds and handles all network communication internally, making it one of the most common network adapters used with HP LaserJet and enterprise-class inkjet printers.

Applications

HP Jetdirect EIO print server cards were introduced in the mid-1990s and became the standard network interface solution for HP's LaserJet line through the 2000s and into the 2010s. The EIO slot is found on a wide range of HP LaserJet models — including the 4000, 4050, 4100, 4200, 4250, 4300, 4345, 5000, 5100, 8000, 8100, 9000, and many others — as well as select HP Color LaserJet and enterprise MFP models. The Jetdirect 620n is still commonly used today to add or restore wired network printing capability on any compatible HP printer with an available EIO bay, and it remains a popular and cost-effective upgrade for keeping older HP laser printers on modern wired office networks.
