Query: Written by non-technically knowledge authors

Never before have I been so disappointed with a product that I felt compelled to go out of my way to write a complaint, until now. I total agree with the with the prior, and then some. This book was clearly written by amateurs that did nothing more than plagiarized technical information from the manufactures technical information.A simple search on the Internet will not only provide you with more information but it will be of far greater quality. Not only should Amazon.com discontinue this product caring this product but also the printer manufacturers should investigate the authors for copyright infringements.I only regret that I didn't discover this review before I wasted my money and purchased this book.
