To connect a printer or other parallel device 
The notebook’s parallel port uses a standard 25-pin connector, most commonly used for 
connecting dot-matrix, ink-jet, and laser printers. 
?? Connect the device’s parallel cable to the notebook’s parallel port (colored burgundy). 
To connect an external keyboard or mouse 
?? Plug a USB mouse or keyboard into a USB port on the notebook. 
In addition, if you dock the notebook in the optional port replicator, you can also connect 
a PS/2 keyboard or PS/2 mouse. 
Note 
The notebook’s touch pad and scroll pad are automatically disabled when the notebook 
is docked in a port replicator with a PS/2 mouse connected. 
 
Note 
USB keyboards do not support Fn hot keys. 
To connect a USB device 
The universal serial buses (USB) on the notebook provide a bi-directional serial interface 
for adding peripheral devices such as a mouse, keyboard, floppy drive, printer, scanner, 
or game controller on a single bus. USB-to-serial and USB-to-parallel port adapters are 
also available.  
?? Attach the device’s USB cable to a USB port. Windows automatically recognizes the 
USB device. Some USB devices can be connected to the notebook in series (called a 
daisy-chain connection).  
Note 
If you have problems making this connection, contact the device manufacturer and the 
HP Business Support web site (www.hp.com/go/bizsupport) for the latest version of the 
driver for the device.
