General guidelines
Some media might meet all of the guidelines in this manual and still not produce satisfactory results.
This problem might be the result of improper handling, unacceptable temperature and humidit\
y
levels, or other variables over which Hewlett-Packard has no control.
Before purchasing large quantities of print media, always test a sample and make sure that the print
media meets the requirements specified in  this user guide and in the HP LaserJet Printer Family
Print Media Guide ,...

Media to avoid
The all-in-one can handle many types of media. Using media that is outside the specifications
degrades print quality and increases the chance of jams occurring.
●Do not use media that is too rough.
● Do not use media that contains cutouts or perforations other than standard 3-hole punched
paper.
● Do not use multipart forms.
● Do not use paper that contains a watermark if you are printing solid patterns.
Media that can damage the all-in-one
In rare circumstances media can damage the...

Guidelines for using media
The following sections provide guidelines and instructions for printing on transparencies, envelopes,
and other special media. Guidelines and specifications are included to help you se\
lect media that
optimizes print quality and avoid media that can cause jams or damage the all-in-one.
Paper
For best results, use conventional 80-g/m2 or 20 lb paper. Make sure that the paper is of good quality
and free of cuts, nicks, tears, spots, loose particles,  dust, wrinkles, voids, and...

Labels
For the HP LaserJet 3050/3052/3055 all-in-one, HP recommends that you print labels from the
priority input slot. For the HP LaserJet 3390/3392 all-in-one, HP recommends that you print labels
from the single-sheet priority input slot (tray 1)  and use the straight-through output path. See 
Loading
media into the input trays for more information.
CAUTION Do not feed a sheet of labels through the all-in-one more than once. The
adhesive degrades and might damage the all-in-one.

Envelopes
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.
See 
Loading media into the input trays  for more information.
Envelope construction
Envelope construction is critical. Envelope fold lines can vary considerably, not only between
manufacturers, but also...

Envelopes with adhesive strips or flaps
Envelopes with a peel-off adhesive strip or with more than one flap that folds over to seal must use
adhesives compatible with the heat and pressure in  the all-in-one: 200°C (392°F). The extra flaps
and strips might cause wrinkling, creasing, or jams.
Envelope storage
Proper storage of envelopes contributes to good print  quality. You should store envelopes flat. If air
is trapped in an envelope, creating an air  bubble, the envelope might wrinkle during...

Letterhead and preprinted forms
Letterhead is premium paper that often has a watermark, sometimes uses cotton fiber, and is
available in a wide range of colors and finishes with matching envelopes. Preprinted forms can be
made of a broad spectrum of paper types ranging from recycled to premium.
Many manufacturers now design these grades of paper with properties optimized for laser printing
and advertise the paper as laser compatible or laser guaranteed. Some of the rougher surface
finishes, such as...
