							3. Slide the width guides on tray 1 outward to a position that is slightly wider than the
envelopes.
4. Place the envelopes into the tray short-edge  in, print-side up. The stamp end must enter
the printer first.
5. Slide the width guides inward until they lightly touch the envelope stack without bending it. The envelopes should be centered between the  paper guides and under the tabs on
the paper-width guides.
NOTEIf the envelope has a flap on the short edge,  this edge must enter the printer first. You might
experience some jams when using any media that  is less than 178 mm (7 inches) long.
Shrinkage might be the result of environmental conditions. For optimum performance, make
sure that you are storing and handling the paper correctly. For more information see 
Printing
and paper storage environment . Using media from another manufacturer might also help.

							Printing on special media
This section discusses printing on types of media that require special handling:
●
Printing on labels
●
Printing on transparencies
●
Printing on custom-sized media or cardstock
●
Printing on letterhead, prepunched, or preprinted paper (single-sided)
Printing on labels
Use only labels that are recommended for laser printers. For label specifications, see Labels .
Guidelines for printing on labels
●Print labels from tray 1.
● Load labels print-side up.
● Use the rear output bin for labels.
● Remove label sheets from the output bin as they are printed to prevent them from
sticking together.
● Do not use labels that are separating from the backing sheet or are wrinkled or damaged
in any way.
● Do not use label sheets that have the backing sheet exposed, and do not reuse partially
used label sheets.
● Do not feed a sheet of labels through the printer more than once. The adhesive backing
is designed for one pass through the printer.
CAUTIONIf a sheet of labels becomes jammed in the printer, see Clearing jams .
50 Chapter 2 Printing tasks ENWW
 
						

							Printing on transparencies
Use only transparencies that are recommended for use in laser printers. \
For transparency
specifications, see 
Transparencies.
Guidelines for printing on transparencies
●Print transparencies from tray 1.
● Use the top output bin to reduce curling (this  is for transparencies only; for other media
use the rear output bin to reduce curling).
● Remove transparencies from the output bin as they are printed to prevent them from
sticking.
● Place transparencies on a flat surface after removing them from the printer.
● Set the printer driver for transparencies. See 
Printing by type and size of media (locking
trays) .
● For Macintosh computers, go to the  HP LaserJet Utility and select transparencies.
Printing on custom-sized media or cardstock
Postcards, 3 x 5 inch (index) cards, and other custom-sized media can be printed from
tray 1. The minimum media size is 76 x 127 mm (3 x 5 inches) and the maximum media size
is 216 x 356 mm (8.5 x 14 inches).
NOTE
You might experience some jams when using any  media that is less than 178 mm (7 inches)
long. Shrinkage might be the result of environmental conditions. For optimum performance,
make sure that you are storing and handling the paper correctly. See 
Printing and paper
storage environment . Using media from another manufacturer might also help. Printing on
odd sizes or weights of media (for example,  small, long, or narrow paper) can decrease print
speed. The decreased speed helps to prolong the  life of internal printer parts. It also
improves print quality with these types of media.
ENWW Printing on special media51
 
						

							Guidelines for printing on custom-sized media and cardstock
●Always insert the short-edge first into tray 1. If you want to print in landscape mode,
make this selection through your software. Inserting paper long-edge first might cause a
jam.
● Use the rear output bin to reduce curl.
● Do not print on media that is smaller  than 76 mm (3 inches) wide or 127 mm (5 inches)
long.
● In the software program, set margins at least  6.40 mm (0.25 inch) away from the edges
of the media.
Printing on letterhead, prepunched, or preprinted paper
(single-sided)
When printing letterhead, prepunched, or preprinted paper, it is important to orient the paper
correctly. Follow the guidelines in this section for printing on one side only. For duplexing
guidelines, see 
Printing on both sides (duplexing) .
Tray 1 orientation:  print-side up, top edge toward the printer.
52Chapter 2 Printing tasks ENWW
 
						

							Tray 2 or tray 3 orientation: print-side down, top edge toward you.
NOTEWhen Alternative Letterhead  mode is enabled in the printer driver, and  Letterhead or
Preprinted  is selected as the media type, you must orient the media for two-sided (duplex)
printing.
Guidelines for printing on letterhead or preprinted forms
● Do not use letterhead paper that is printed with low-temperature inks, such as those
used in some types of thermography.
● Do not use raised or embossed letterhead.
● The printer uses heat and pressure to fuse toner to the paper. Make sure that any
colored paper or preprinted forms use inks that are compatible with this fusing
temperature (200°C or 392°F for 0.1 second).
ENWW Printing on special media53
 
						

							Printing on both sides (duplexing)
You can print on both sides of a sheet of paper (called duplexing or two-sided printing) in
two ways—automatic and manual. The following paper sizes are supported for automatic
duplexing: Letter, A4, Legal, and 8.5 x 13  inches. Manual duplexing supports all paper sizes.
● Automatic duplexing:  The built-in, automatic duplexer is included only with the
HP LaserJet 2420d, 2420dn, and 2430dtn printer models.
● Manual duplexing:  All printer models are capable of manual duplex printing. The printer
prints the first side of each page, waits for you to reinsert the paper into the printer, and
then prints the second side  of each page. Other documents cannot be printed while the
printer waits for you to insert the paper for the second side to be printed.
Even if the printer includes a built-in duplexer, manual duplexing is necessary for the
following situations:
● When duplexing paper other than the supported sizes or weights—for example, paper
heavier than 105 g/m
2 (28 lb) or very thin paper.
● When you select  Straight Paper Path  in the printer driver
CAUTION
Do not print on both sides of labels,  transparencies, or vellum. Damage to the printer and
jams might result.
Paper orientation for printing on both sides
Print on the second side of the sheet of paper first. The paper needs to be oriented as
shown in the following illustration.
● For tray 1, load the first side facing down  with the bottom, short edge toward the printer.
● For all other trays, load the first side facing  up with the top, short edge toward the printer.

1. Long-edge landscape*This layout is often used in accounting, data processing, and
spreadsheet programs. Every other printed image is oriented
upside-down. Facing pages 
are read continuously from top to
bottom.
2. Short-edge landscapeEach printed image is oriented right-side-up. Facing pages are
read from top to bottom on the left page, then from top to bottom
on the right page.
3. Long-edge portraitThis is the default printer setting, and the most common layout
used, with every printed image oriented right-side-up. Facing
pages are read from top to bottom on the left page, then from top
to bottom on the right page.
4. Short-edge portrait*This layout is often used  with clipboards. Every other printed
image is oriented upside-down. Facing pages are read
continuously from top to bottom.
* When using Windows drivers, select  Flip Pages Up to get the designated binding options.
To duplex by using the built-in duplexer
The built-in duplexer is included only with  the HP LaserJet 2420d, 2420dn, and 2430dtn
models.
1. Insert enough paper into one of the trays to accommodate the print job. If you are loading special paper such as letterhead, load it in one of the following ways:
●For tray 1, load the letterhead paper  with the front side down, bottom-edge first.
● For all other trays, load the letterhead paper  with front side facing up, and the top
edge toward the back of the tray.
CAUTION
Do not load paper that is heavier than 105 g/m2 (28 lb bond). Jamming could result.
2. Open the printer driver (see 
Changing the settings for a print job ).
3. On the  Finishing tab, select  Print on Both Sides .

5. Send the print job to the printer.
NOTE
The paper you are printing on will partially come out of the top output bin during the
duplexing. Do not pull on the paper until duplexing is complete. During duplexing, the
duplexer will not function if the rear output bin is open.
To duplex manually
1. Insert enough paper into one of the trays to accommodate the print job. If you are loading special paper such as letterhead, load it in one of the following ways: 
●For tray 1, load the letterhead paper  with the front side down, bottom-edge first.
● For all other trays, load the letterhead paper with first side up, top edge toward the
back of the tray.
2. Open the printer driver (see 
Changing the settings for a print job ).
3. On the  Finishing tab, select  Print on Both Sides .
4. Click  OK.
5. Send the print job to the printer.
6. Go to the printer. Remove any blank paper that  is in tray 1. Insert the printed stack with
the blank side up, with the  top-edge feeding into the printer  first. You  must print the
second side from tray 1.
7. If prompted by a message at the control panel-display, press 
 (SELECT button).
NOTE
If the number of total sheets exceeds the  tray 1 capacity for manual duplex jobs, you must
repeat steps 6 and 7 each time that paper  is inserted, until the duplexing job is complete.

							Canceling a print job
You can cancel a print job from a software program or a print queue, or by pressing the STOP
button on the printer control panel.
●If the printer has not started printing, first  try to cancel the job within the software
program that sent the print job.
● If the print job is waiting in a print queue  or print spooler such as the Printers group on a
Windows computer or Print Monitor on a Macintosh computer, delete the job there.
● If the print job is  already printing, press the  S
TOP button. The printer will finish printing
any pages that are already moving through the printer  and delete the rest of the print job.
If the control-panel status lights continue to cycle after a job has been canceled, the
computer is still sending the job to the printer. Either delete the job \
from the print queue or
wait until the computer has finished sending data  (the printer will return to the ready state,
with the Ready light on).
Pressing  S
TOP cancels only the current job in the printer.  If more than one print job is in
printer memory,  S
TOP must be pressed once for each job.
ENWW Canceling a print job57
 
						

							Using the printer driver
The printer driver provides access to the printer features and allows the computer to
communicate with the printer. This section provides instructions for printing when setting
options are set from the printer driver. 
If possible, try to set printing features from the software program in which you are working or
from the Print dialog box. You can set the  printer features this way for most Windows and
Macintosh software programs. If a setting is not available in the software program or printer
driver, you must set it at the printer control panel.
For more information about printer-driver features, see the printer-driver online Help. For
more information about printing from a specific software program, see the documentation for
the program.
NOTE
Printer-driver settings override control panel settings. Software program settings override
both printer-driver settings and control panel settings.
