HP LaserJet 1018 Printer - Manual (Page 35)

Printing an envelope
Only use envelopes that are recommended for laser printers. See Printer media
considerations for more information.
NOTE Use the priority feed slot for printing one envelope. Use the main input tray for printing
multiple envelopes.
1. Before loading the envelope, slide the media guides outward to slightly wider than the
envelopes.
NOTE If the envelope has a flap on the short edge, feed that edge into the printer first.
2. Place the envelope with the side to be printed facing up and the top edge along the left
media guide.
3. Adjust the media guides to the width of the envelope.
