To connect a printer or other parallel device 
The computer’s parallel port uses a standard 25-pin connector, most commonly used for 
connecting dot-matrix, ink-jet, and laser printers. You can also use it to connect a parallel 
Zip drive. 
•  Connect the cable from the parallel printer or other parallel device to the computer’s 
parallel port. 
To connect an external keyboard or mouse 
•  Plug a USB mouse or keyboard into a USB port on the computer. 
–or– 
•  Plug a PS/2 mouse or keyboard into a PS/2 port on the computer. 
The pointing stick and touch pad are normally disabled while an external PS/2 mouse is 
connected. 
To connect a PS/2 mouse and keyboard at the same time, use the HP F1469A Y adapter.  
Note 
To use hot keys from an external PS/2 keyboard, substitute left CTRL+left ALT for the 
computer Fn key. For example, to access Fn+F12, press left CTRL+left ALT+F12. Only 
Fn+F5, Fn+F7, and Fn+F12 are supported on an external PS/2 keyboard. A USB 
keyboard does not support Fn hot keys. 
To connect a USB device 
Your computer’s universal serial bus (USB) provide a bi-directional serial interface for 
adding peripheral devices such as game controllers, serial and parallel ports, and scanners 
on a single bus.  
•  Attach the device’s USB cable to one of the computer’s USB ports. Windows 
automatically recognizes the USB device. Some USB devices can be connected to the 
computer in series—this is called a daisy-chain connection.  
Note 
If you have problems making this connection, contact the device manufacturer and the 
HP Customer Care Web site (www.hp.com/go/support) for the latest version of the 
driver for the device.
