HP LaserJet 1018 Printer - Manual (Page 37)

Printing multiple envelopes
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 envelopes, slide the media guides outward to slightly wider than the
envelopes.
2. Place the envelopes with the side to be printed facing up and the top edge along the left
media guide. Stack up to 15 envelopes.
NOTE If the envelopes have a flap on the short edge, feed that edge into the printer first.
3. Adjust the media guides to the length and width of the envelopes.
