It looks like an old problem with many posts, but I never saw a solution identified.

 

I just got a Latitude D630 as a replacement for a D600.  Both run Windows XP.  The D600 had a DB25 printer port that hooked up to the PSC 500 HP supplied cable.  It worked fine.

 

The D630 does not.  So I bought a USB to DB25 Parallel adaptor cable from CompUSA. 

 

The computer recognizes the PSC 500 when connected to the USB port but the Hardware Wizard says the hardware was not installed because the wizard cannot find the necessary software.
