the 1284.4 driver is a generic driver.
first, download the photosmart software/driver for xp: http://h10025.www1.hp.com/ewfrf/wc/softwareList?os=228&lc=en&cc=us&dlc=en&product=72881&lang=en
next uninstall the printer and reboot.... don't allow windows to find/install the software automatically.
lastly, run the photosmart software to install the hp driver.
Our system will not go into standby and there is a message on my wife's desktop that says "The device driver for the 1284.4 compatable printer is preventing the machine from entering standby"
This message does not come up on my desktop. If my wife logs off, the system will go into standby.
