HP LaserJet 1020 Plus Printer - Manual (Page 35)

Printing an envelope
Only use envelopes that are recommended for laser printers. See Printer media considerations
on page 11 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.
