If this doesn't work try
Option 2: Dot4_001 (Generic IEEE 1284.4 Printing Support)
Click "Next"
Select "HP" under Manufacturer
Select "HP OfficeJet Pro L7600" or "HP Photosmart 7200)"
Click "Next"
The program will install and let you know that it installed successfully. It will then run a test print page. If it works-congratulations!
If it didn't: I advise deleting the "HP L7600 or HP 7200 series" you downloaded and go through the steps again. Find the closest match to your series and download. You will eventually find the one that works for you-I did!
Rememeber! Delete the series that didn't work for you before downloading another series.
Baby steps...
