Hi, I had the exact same problem, install the Win7-64 bit driver for the newer model Designjet 130 and it worked just fine.
I read your reply to the 120nr problem with windows 7. I also installed drivers for the 130 but with no luck . I did get the printer to show up on my printer list but when I try to print it does nothing, but does say documents waiting to be printed. If it is possible for you to give me any help I would appreciate it . I use chief artitect cad program and i am totaly lost
