Pros: Plug-and-play Windows Update had the drivers Automatically detected older connected HP LaserJet and Windows Update installed those drivers as well. Exactly as advertised

Cons: None (Didn't set up serial ports, no experience there)

Overall Review: Needed to maintain several older HP LaserJets with some new Win 7 Pro 64-bit machines with no parallel ports. USB to parallel cables are a joke, would not work. Card slid right in, fired up Windows, it picked up the card, installed all drivers for the parallel and 2 serial ports, and even located the exact printer, all drivers from Windows Update. Perfect solution.
