Cracking Open the HP JetDirect EX Plus

HP JetDirect EX Plus

In this gallery, we will be taking a look at the HP JetDirect EX Plus Print Server (HP Part Number J2591A). Back in the 90's, before HP started putting network cards in their printers, they sold these devices to translate a network signal in to a then-standard LPT printer port. Although I don't know exactly when it was purchased, I can assume this particular device was created in the mid to late 90's, as we will see proof of later. This print server accepted both BNC "Thin-Net" connections as well as the then-emerging 10Base-T Ethernet network standard.
