HT1341 I can't add an HP color LaserJet 2550L printer to Mac 10.8.5

I'm trying to connect my 15" MacBook Pro early 2011 (MacOSX10.8.5)
to HP color LaserJet 2550L
using USB
The cable works fine on Windows PC.
No printer can be added at all.  This is a Bug in Mac OSX Lion


Read the user manual that came w/the printer and/or contact HP Support. OS X Mountain Lion: Troubleshoot a network printer OS X Mountain Lion: Reset the printing system Printer and scanner software available for download
This is a Bug in Mac OSX Lion
Which is OS 10.7.x.
