							●On the Embedded Web Servers Submit Job page: select Advanced settings >
Resizing.
●The Standard and Custom options adjust the image size to the standard or custom paper
size you have selected. For example, if you have selected ISO A2 as the paper size and you
print an A3-sized image, it is enlarged to fit the A2 paper. If the ISO A4 paper size is selected,
the printer reduces a larger image to fit the A4 size.
●The % of actual size option enlarges the printable area of the original paper size (the page
minus the margins) by the percentage indicated, then adds the margins to create the output
paper size.
●
Using the front panel: select the Setup menu icon 
, then Printing preferences >
Paper > Resize.
If you are printing to a single sheet, you must ensure that the image can actually fit onto the sheet, otherwise
the image will be clipped.
Change the treatment of overlapping lines
NOTE:This topic applies only when printing an HP-GL/2 job.
The merge option controls the overlapping lines in an image. There are two settings:

Print with no margins
Printing with no margins (to the edges of the paper) is known as borderless printing. This can be done
only on rolls of glossy paper.
In order to be sure of leaving no margins, the printer prints slightly past the edges of the paper. Any ink
deposited outside the paper is absorbed by the sponge situated in the platen.
NOTE:If you wish to print with no margins, you must ensure that your image will fill the page.
If your image is smaller than the page, it will not be automatically stretched.
You can request printing with no margins in the following ways:
●In the Windows driver dialog: select the Paper/Quality tab and press the Layout button.
Then select Borderless.
●In the Mac OS Page Setup dialog (PostScript driver): select a paper size name that includes
the words “no margins”. Then, in the Print dialog, select Finishing > Layout > Borderless.
●In the Mac OS Page Setup dialog (PCL driver): select a paper size name that includes the
words “no margins”. Then, in the Print dialog, select Paper Type/Quality > Layout >
Borderless.
●On the Embedded Web Servers Submit Job page: select Advanced settings >
Paper > Layout/Margins > Borderless.
When you select Borderless, you must also select one of the following Image Enlargement options:
●Automatically by Printer means that the printer automatically enlarges your image slightly
(normally by a few millimeters in each direction) in order to print over the edges of the paper.
●Manually in Application means that you must enlarge the image yourself in your application,
and select a custom paper size that is slightly larger than the actual paper size.
NOTE:If the first print job after loading paper is a borderless job, the printer may trim the leading
edge of the paper before printing.
At the end of a borderless print, the printer normally cuts the print slightly inside the image area to
ensure that the print is borderless. It then cuts the paper again so that no residual part of the image
is included in the next print. However, if the job is cancelled, or if there is white space at the bottom
of the image, only a single cut is made.
Rotate an image
By default, images are printed with their shorter sides parallel to the leading edge of the paper, like this:
56 Chapter 5   PrintingENWW
Printing
 
						

							You may wish to rotate your images by 90 degrees in order to save paper, like this:
You can do this in the following ways:
●In the Windows driver dialog: select the Features tab, then Rotate by 90 degrees.
●In the Mac OS Print dialog (PostScript driver): go to the Finishing panel and select Rotate
by 90 degrees.
●On the Embedded Web Servers Submit Job page: select Advanced settings > Roll
options > Rotate.
●
In the front panel: select the Setup menu icon 
, then Printing preferences > Paper >
Rotate.
NOTE:If rotation is set from your computer, it overrides the setting in the front panel.
NOTE:When you rotate a job, the page length may be increased to avoid clipping, because
the top and bottom margins are usually larger than the side margins.
CAUTION:With either rolls or sheets, if you rotate an image to landscape whose original
orientation was portrait, the paper may not be wide enough for the image. For example, rotating
a portrait D/A1-size image on D/A1-size paper by 90 degrees will probably exceed the width of
the paper. If you are using the Embedded Web Server, the preview screen will confirm this with a
warning triangle.

							Autorotate
With some printer drivers, you can also select the Autorotate option, which will automatically rotate by
90 degrees any oversized portrait images in order to save paper.
Print with crop lines
Crop lines indicate where the paper should be cut to reduce it to your selected page size. You can print
crop lines automatically with individual jobs in the following ways:
●On the Embedded Web Servers Submit Job page: select Advanced settings > Roll
options > Enable crop lines.
●
Using the front panel: select the Setup menu icon 
, then Printing preferences >
Paper > Enable crop lines > On.
To print crop lines with nested jobs (see 
Nest jobs to save roll paper on page 58), you must select a
different option:
●In the Embedded Web Server: select Job management > Use crop lines when nest is
enabled > On.
●
Using the front panel: select the Setup menu icon 
, then Job management > Nest
options > Enable crop lines > On.
Use paper economically
Here are some recommendations for making economical use of paper:
●If you are printing relatively small images or document pages, you can use nesting to print them side
by side instead of one after another. See 
Nest jobs to save roll paper on page 58.
●If you are printing multipage documents with relatively small pages, you can print up to 16 of them
on one sheet of paper. Use the Pages per sheet option in the Features tab (Windows driver) or
the Layout panel (Mac OS driver).
●You may be able to save some roll paper by using the following options:
●In the Windows driver dialog: select the Features tab and then Remove Top/Bottom
Blank Areas and/or Rotate by 90 degrees.
●In the Mac OS Print dialog (PostScript driver): select the Finishing panel, then
Remove Top/Bottom Blank Areas and/or Rotate by 90 degrees.
●In the Mac OS Print dialog (PCL driver): select the Paper Type/Quality panel,
then Paper, then Remove Top/Bottom Blank Areas.
●On the Embedded Web Servers Submit Job page: select Advanced settings >
Roll options > Remove top/bottom blank areas and/or Rotate.
●If you check the print preview on your computer before printing, you can sometimes avoid wasting
paper on prints containing obvious mistakes. See 
Preview a print on page 51.
Nest jobs to save roll paper
Nesting means automatically printing images or document pages side by side on the paper, rather than
one after the other. This is done to avoid wasting paper.

4.Paper saved by nesting
When does the printer try to nest pages?
When both of the following are true:
●The printer is loaded with roll paper, not sheet paper.
●In the front panels Job Management menu or the Embedded Web Servers Job Management
page, Nest is On.
What pages can be nested?
All pages can be nested, unless they are so large that two of them cannot fit side by side on the roll, or
unless there are too many of them to fit into the remaining length of the roll. A single group of nested
pages cannot be split between two rolls.
Which pages qualify for nesting?
In order to be in the same nest, the individual pages must be compatible in all of the following ways:
●All pages must have the same print quality setting (Fast, Normal, or Best).
●The Maximum Detail and More Passes settings must be the same on all pages.
●The Margins setting must be the same for all pages (Extended or Normal).
●The Mirror Image setting must be the same for all pages.
●The Rendering Intent must be the same for all pages.
●The Cutter setting must be the same for all pages.
●The color adjustment settings must be the same for all pages. See 
Color adjustment options
on page 76.
●Pages must be all color, or all grayscale: not some in color and some in grayscale.
ENWW Nest jobs to save roll paper 59

							●All pages must be in one or other of the following two groups (the two groups cannot be mixed in
the same nest):
●HP-GL/2, RTL, CALS/G4
●PostScript, PDF, TIFF, JPEG
●JPEG, TIFF, and CALS/G4 pages with resolutions greater than 300 dpi may not nest with other pages
in some cases.
How long does the printer wait for another file?
So that the printer can make the best nest possible, it waits after a file has been received to check whether
a subsequent page will nest with it or with pages already in the queue. This waiting period is the nest
wait time; the factory default nest wait time is two minutes. This means that the printer waits for up to two
minutes after the last file is received before printing the final nest. You can change this waiting time from
the printers front panel: select the Setup menu icon 
, then Job management options > Nest
options > Select wait time. The available range is 1 to 99 minutes.
While the printer is waiting for nesting to time out, it displays the remaining time on the front panel. You
can print the nest (cancel the nest wait) by pressing the Form feed and cut key.
Use ink economically
Here are some recommendations for making economical use of ink.
●For draft prints, use plain paper and move the print-quality slider to the left end of the scale (Speed).
●Clean the printheads only when needed, and clean only those printheads that need cleaning.
Cleaning the printheads can be useful, but it uses ink.
●Leave the printer permanently turned on so that it can maintain the printheads in good condition
automatically. This regular printhead maintenance uses a small amount of ink. However, if it is not
done, the printer may need to use much more ink later to restore the health of the printheads.
●Wide prints make more efficient use of ink than narrow prints, because printhead maintenance uses
some ink, and its frequency is related to the number of passes made by the printheads. Therefore,
nesting jobs can save ink as well as saving paper (see 
Nest jobs to save roll paper on page 58).
