The HP LaserJet 4200 printer was released by HP in November of 2002, and it was updated in mid-2003 with a slight refresh. The first series of these printers sold did not have an integrated USB port. The updated model had the USB port built in, and it was later called the HP 4250. If you have an HP 4200 printer without a built in USB port, you can install a JetDirect EIO expansion card to give it network and USB capabilities. Inserting a JetDirect card into an HP printer is similar to inserting an expansion card into a PC.
