Conveniently, the printer can detect a wide variety of paper types (envelopes, cardstock, labels, and transparencies) and sizes and will automatically pull from the correct tray to get the job done. There's also a separate 50-sheet manual input tray with adjustable paper guides for longer media, and HP sells an additional 250 sheet tray on its Web site for $50. The main paper output tray sits at the bottom of the printer and can hold up to 250 sheets of plain 20-pound paper.
