"The mono office laser printer is still one of HP's core products and
the LaserJet P3005x is a fast and versatile member of its latest
generation. It comes as standard with duplex capability and two paper
trays, each of which can take a full, 500-sheet ream of paper. This
means you can set it up with letterheads and follow-on sheets, and still
have a multi-purpose tray for special media, such as envelopes."
