Query: Don't waste your time and money

Unfortunately, I ignored the advice of the other people who rated this product, and I bought this item. I followed the installation instructions to the letter. All of the settings were set just as they were supposed to be according to the installation instructions, but my LaserJet 4L would not print. In all, I spent about 2 hours trying to get this item to work. What a waste of time. Even the uninstall process doesn't work--I had to reinstall my original print driver to get my printer to work again.
