I have lost my CD ROM for HP Deskjet 1280 and want to download a replacement

The replacement drivers can be downloaded from here: http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?lc=en&dlc=en&cc=us&tool=&query=%20HP%20DeskJet%201280&product=439150&
You will need to select your Operating system, then press the + next to Drivers, then select the driver package you want. To get the closest to what the CD had, select the FULL feature package, not the simple PCL or PS package.
Hope this helps!
