USB Device Compatibility

Overview

The Keyspan 4-Port Print Server hardware (model PS-4A) supports USB printers and USB multi-
function printers.
The 4-Port Print Server supports up to 8 USB printers on one 4-Port Print Server. While the 4-Port
Print Server only has 4 USB ports, we support 8 devices due to how Compound USB devices
work. Compound USB devices are devices that have multiple components connected to an
embedded USB hub inside 1 USB printer. For example, the Lexmark X1150 is a compound
device that has 2 components (one for the scanner, one for the printer). The Canon i475D is also a
compound device that has 3 components (the printer, the card reader, and a HID device [for buttons
on the printer]).
Tech Note About USB Devices:
Technically speaking, USB devices can either be a single USB printer (a USB printer
that contains only one component ie a single button mouse), a composite USB
printer (a device that contains multiple components but appears as one device ie a
multifunction printer), or a compound USB printer (a device that has multiple
components that are tied together by an embedded USB hub inside the USB printer
itself ie a printer with a card reader, a keyboard with a port to connect a mouse, etc.).
Using single and composite USB devices via the 4-Port Print Server is identical to
using them when connecting to built-in port. By default, compound USB devices
also work the same way as when they are connected to a built-in port however you can
OPTIONALLY configure the 4-Port Print Server to allow you to connect to certain
components of a compound device instead of connecting every component. This is
useful if you just want to connect the printer component of a multi-function so that you
don't get any message screens regarding the scan component of that device.
