Enhanced I/O (EIO) configuration
This feature is available for the HP Color LaserJet 3000 and 3800 Series printers only.
If you are adding a print server to a base model (HP Color LaserJet 3000 or HP Color LaserJet 3800), additional printer memory might be required.
The enhanced input/output (EIO) slot holds compatible accessory devices, such as the HP Jetdirect print server network cards or other devices. Plugging an EIO network card into the slot increases the number of network interfaces available to the printer.
