For the HP LaserJet 3050/3052/3055 all-in-one, HP recommends that you print envelopes from the
priority input slot. For the HP LaserJet 3390/3392 all-in-one, HP recommends that you print
envelopes from the single-sheet priority input slot (tray 1) and use the straight-through output path.

Envelope construction
Envelope construction is critical. Envelope fold lines can vary considerably, not only between
manufacturers, but also within a box from the same manufacturer. Successful printing on envelopes
depends upon the quality of the envelopes. When selecting envelopes, consider the following
components:
● Weight: The weight of the envelope paper should not exceed 90 g/m 2 (24 lb), or jamming might
result.
● Construction: Before printing, envelopes should lie flat with less than 6 mm (0.25 inch) of curl,
and should not contain air. Envelopes that trap air can cause problems. Do not use envelopes
that contain clasps, snaps, tie strings, transparent windows, holes, perforations, cutouts,
synthetic materials, stamping, or embossing. Do not use envelopes with adhesives that require
pressure to seal them.
● Condition: Make sure that the envelopes are not wrinkled, nicked, or otherwise damaged.
Make sure that the envelopes do not have any exposed adhesive.
Envelopes with double-side seams
An envelope with double-side-seam construction has vertical seams at both ends of the envelope
rather than diagonal seams. This style might be more likely to wrinkle. Make sure that the seam
extends all the way to the corner of the envelope as shown in the following illustration:
