We replaced a HP Laserjet 401dne when it reported paper jam that could note be fixed with the 4001dn. The new Laserjet is faster, also has double sided printing, and is straightforward in its operation. Installation was simple with connecting the power cord and the Cat 5 computer cable. The printers was rapidly recognized and the installation software quickly downloaded. Next is to see if it will also last 10 years as the HP 401dne printer did.
I bought this as a replacement for my old 1020, mainly because of price. I love having two paper trays, and the ability to load the large one with a good number of sheets. On the minus side, it is noisier than the 1020 and slower in getting ready: it takes about 18 seconds for the printing to start.
