							Select print quality
The printer has various print-quality options because best-quality printing requires some loss of speed,
while fast printing implies some reduction in print quality.
Therefore, the standard print-quality selector is a slider that allows you to choose between quality and
speed. With some paper types, you can choose a compromise position between the two.
Alternatively, you can select from the custom options: Best, Normal and  Fast. If you select  Fast, you
can also select  Economode, which uses a lower rendering resolution and consumes less ink. It
therefore increases printing speed even further, but reduces print quality.  Economode can be selected
only from the custom options (not from the slider).
There is also a supplementary custom option that may have an effect on print quality:  Maximum
detail . See 
High-quality printing on page 50.
NOTE: In the Windows driver dialog, the rendering resolution for your job is displayed in the Custom
Print Quality Options dialog box (select  Custom options and then Settings ). In the Mac OS Print dialog,
it is displayed in the  Summary panel.
You can select print-quality options in the following ways:
●In the Windows driver dialog: go to the 
Paper/Quality tab and look at the Print Quality section.
If you select Standard Options , you will see a simple slider with which you can select speed or
quality. If you select  Custom Options, you will see the more specific options described above.
● In the Mac OS Print dialog:
 go to the Paper Type/Quality  panel and select Paper . If you
select  Standard  quality options, you will see a simple slider with which you can select speed or
quality. If you select Custom  quality options, you will see the more specific options described
above.
● Using the front panel:  select the Setup menu icon 
, then Printing preferences > Print
quality .
NOTE: If the print quality is set from your computer, it overrides the print-quality setting in the
front panel.
NOTE: You cannot change the print quality of pages that the printer is already receiving or has already
received (even if they have not started to print yet).
Select paper size
The paper size can be specified in the following ways.
NOTE: The paper size specified here should be the paper size in which the document was created.
It is possible to rescale the document to a different size for printing. See 
Rescale a print on page 48 .
● In the Windows driver dialog:
 select the Paper/Quality tab, then select your paper size from the
Document Size list.
● In the Mac OS Page Setup dialog:
 select your printer from the Format for list, then select your
paper size from the Paper Size list.
● Using the front panel:  select the Setup menu icon 
, then Printing preferences > Paper
options  > Select paper size .
NOTE:If the paper size is set from your computer, it overrides the paper size setting in the front
panel.

							Custom paper sizes
To choose a non-standard paper size not shown in the list of paper sizes:
●Under Windows,
 there are two different ways:
◦ In the driver dialog, click the 
Custom button in the Paper/Quality  tab, then specify the name
and the dimensions of your new paper size, then click Save  to save your new paper size. To
see your new custom size in the list of custom sizes, you need to exit the printer properties,
then reenter them (and use the More  button if necessary).
NOTE:The driver will not allow you to create a paper size whose width exceeds its length.
◦From the Start menu, select 
Printers and Faxes, then from the File menu select  Server
Properties . In the Forms tab, check the  Create a new form  box, specify the name and
dimensions of the new form, then click  Save Form.
● Under Mac OS X 10.4:
 select Paper Size > Manage Custom Sizes  in the Page Setup dialog.
● Under Mac OS X 10.3:
 select Settings > Custom Paper Size  from the Page Setup  dialog.
Select margins options
By default, the printer leaves a 5 mm margin between the edges of your image and the edges of the
paper (increased to 17 mm at the foot of cut-sheet paper). However, you can change this behavior in
several ways.
●In the Windows driver dialog:
 select the Paper/Quality  tab and then the  Margins/Layout button.
● In the Mac OS Print dialog:
 select the Paper Type/Quality  panel and then Layout.
You will then see at least some of the following options.
NOTE: Under Mac OS, the available margins options depend on the paper size selected in the  Page
Setup  dialog. For instance, for borderless printing you must select a paper size name that includes the
words “no margins”.
● Standard. Your image will be printed on a page of the size you have selected, with a narrow margin
between the edges of the image and the edges of the paper. The image should be small enough
to fit between the margins.
● Oversize
. Your image will be printed on a page slightly larger than the size you have selected. If
you cut off the margins, you will be left with a page of the size you selected, with no margins
remaining between your image and the edges of the paper.
● Clip Contents By Margins
. Your image will be printed on a page of the size you have selected,
with a narrow margin between the edges of the image and the edges of the paper. In this case, if
the image is the same size as the page, the printer assumes that the extreme edges of the image
are either white or unimportant, and do not need to be printed. This may be useful when your image
already contains a border.
● Borderless
. Your image will be printed on a page of the size you have selected, with no margins.
The image is slightly enlarged to ensure that no margin is left between the edges of the image and
the edges of the paper. If you select  Automatically by Printer, this enlargement is done
automatically. If you select Manually in Application , you must select a custom page size slightly
larger than the page on which you intend to print. See also  51
.
Print with shortcuts
The printer driver provides many options that can be set to different values when printing a particular
job. A printing shortcut stores the values of all these options that are appropriate for a particular kind of
ENWW Select margins options 47
Printing
 
						

							job, so that you can set them all with a single click. Some settings (such as paper size, paper source
and orientation) may be overridden by the values provided by your application.
To use a shortcut, select the Printing Shortcuts tab in the Windows driver dialog.
NOTE:Shortcuts are available only under Windows.
You can see a list of available shortcuts; select the one that matches the kind of job you want to print.
The driver options are now adjusted to suit your job. You can either print immediately, or examine the
settings to check that you agree with them. If you like, you can select a shortcut and then change some
of its settings manually.
TIP:Check at least the settings that you can see in the  Printing Shortcuts tab: the document size,
orientation, etc.
The Factory Defaults shortcut contains the printers default settings. When you click on it, it sets all
options to their default values.
Printing shortcuts can be customized to your particular needs. To create your own shortcut:
1. Select the shortcut that comes closest to satisfying your requirements.
2. Change any value in the Printing Shortcuts  tab and/or other tabs.
3. Save the new printing shortcut.
If you decide later that you no longer want a shortcut, you can delete it.
Rescale a print
You can send an image to the printer at a certain size but tell the printer to rescale it to a different size
(normally larger). This may be useful:
● If your software does not support large formats
● If your file is too large for the printers memory—in this case, you can reduce the paper size in your
software and then scale it up again using the front-panel option
48 Chapter 6   Printing ENWW
Printing
 
						

							You can rescale an image in the following ways:
●In the Windows driver dialog: go to the 
Features tab and look at the Resizing Options section.
◦ The 
Print document on  option adjusts the image size to the 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.
● In the Mac OS Print dialog: select the 
Paper Handling panel, then Scale to fit paper size , and
select the paper size to which you want to scale the image. If you want to increase the size of the
image, make sure that the  Scale down only box is unchecked.
● Using the front panel:  select the Setup menu icon 
, then Printing preferences  > Paper
options  > 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:
●Off: where the lines cross, only the color of the top line is printed.
● On: where the lines cross, the colors of the two lines merge.
To turn merge on, go to the front panel and select the Setup menu icon 
, then  Printing
preferences  > HP-GL/2 options  > Enable merge . You can set the merge option from your software
in some applications. Settings in your software override the front-panel settings.
Print a draft
You can specify fast draft-quality printing in the following ways:
● In the Windows driver dialog:
 go to the Paper/Quality  tab and look at the Print Quality section.
Move the print-quality slider to the extreme left (Speed).
● In the Mac OS Print dialog:
 go to the Paper Type/Quality  panel and select Paper, then move
the print-quality slider to the extreme left (Speed).
● Using the front panel:  select the Setup menu icon 
, then Printing preferences  > Print
quality  > Select quality level  > Fast.

							You can specify even faster draft-quality printing by using Economode, as follows. This is intended
mainly for documents containing only text and line drawings.
●In the Windows driver dialog: go to the 
Paper/Quality tab and look at the Print Quality section.
Select  Custom Options , then set the quality level to  Fast and check the  Economode box.
● In the Mac OS Print dialog:
 go to the Paper Type/Quality  panel and select Paper , then set the
quality options to  Custom, set quality to  Fast and check the  Economode box.
● Using the front panel:  select the Setup menu icon 
, then Printing preferences > Print
quality  > Enable economode .
NOTE:If the print quality is set from your computer, it overrides the print-quality setting in the front
panel.
High-quality printing
You can specify high-quality printing in the following ways:
● In the Windows driver dialog: go to the 
Paper/Quality tab and look at the Print Quality section.
Move the print-quality slider to the extreme right (Quality).
● In the Mac OS Print dialog:
 go to the Paper Type/Quality  panel and select Paper , then move
the print-quality slider to the extreme right (Quality).
● Using the front panel:  select the Setup menu icon 
, then Printing preferences > Print
quality  > Select quality level  > Best.
NOTE: If the print quality is set from your computer, it overrides the print-quality setting in the front
panel.
If you have a high-resolution image
If your image has a resolution greater than the rendering resolution (which you can see in the Custom
Print Quality Options box under Windows), print sharpness may be improved by selecting the Maximum
Detail option. This option is available only if you are printing on glossy paper and you have selected
Best  print quality.
● In the driver dialog (Mac OS Print dialog):
 select Custom instead of Standard print-quality
options, then check the  Maximum Detail box.
● Using the front panel:  select the Setup menu icon 
, then Printing preferences > Print
quality  > Enable maximum detail .
NOTE:The Maximum Detail option results in slower printing with photo papers, but it does not increase
the amount of ink used.

							Print in gray shades
You can convert all colors in your image to shades of gray in the following ways:
●In your application program:
 many programs provide this option.
● In the Windows driver dialog: go to the 
Color tab and look at the Color Options section.
Select  Print in Grayscale . You can also select  Print in pure black and white  if you want only
black and white, without gray shades.
● In the Mac OS Print dialog:
 go to the Paper Type/Quality  panel and select Color, then select
Print In Grayscale . You can also select  Pure Black and White  if you want only black and white,
without gray shades.
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.
You can request printing with no margins in the following ways:
● In the Windows driver dialog: select the 
Paper/Quality tab and press the Margins/Layout
button. Then select  Borderless.
● In the Mac OS Page Setup dialog:
 select a paper size name that includes the words “no margins”.
Then, in the Print  dialog, select Paper Type/Quality  > Layout > 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.Reprint last printed job
You can reprint the last job printed from the front panel. Select the Job management menu icon ,
then  Reprint last job .
NOTE:You cannot use this method for PCL3 jobs. To reprint old jobs that are PCL3, you may be able
to use your operating systems printer spooler, if you have already set the spooler to save old jobs. This
facility depends on your operating system.

							Use paper economically
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:
 select the Paper Type/Quality  panel, then Paper, then Remove Top/
Bottom Blank Areas .
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). For further economy, select custom print quality options, then select Fast
 and
Economode .
● Clean the printheads only when needed, and clean only those printheads that need cleaning.
Cleaning the printheads can be useful, but it uses a small amount of 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.

							Introduction
HP Designjet T620 printers have been engineered with advanced hardware and software features to
ensure predictable and dependable results.
●Color calibration for consistent colors.
● One gray and two black inks provide neutral grays on all paper types.
● The Photo Black ink provides pure blacks when printing on photo papers.
● Color emulation of other HP Designjet printers.
How colors are represented
All devices that display color use a color model to represent color in numerical terms. Most monitors
use the RGB (Red-Green-Blue) color model, while most printers use the CMYK (Cyan-Magenta-Yellow-
blacK) color model.
An image can be converted from one color model to another, but in general the conversion is not perfect.
Your printer uses the RGB color model: the same color model that is used by your monitor.
This simplifies but does not completely solve the problem of matching colors. Each device represents
colors a little differently from another device, even if they use the same color model. However, software
can adjust the colors in an image according to the characteristics of the particular device, using a color
profile of the device, in order to achieve correct colors.
A summary of the color management process
To get the accurate and consistent colors that you want, you should follow these steps for each paper
type that you use.
1.
Color-calibrate the paper type, for consistent colors. Calibration should be repeated every now and
then (see 
Color calibration on page 54). In addition, you may wish to calibrate immediately before
a particularly important print job for which color consistency is vital.
2. When printing, select the correct color profile for the paper type you are using.
Color calibration
Color calibration enables your printer to produce consistent colors with the particular printheads, inks
and paper type that you are using, and under your particular environmental conditions. After color
calibration, you can expect to get similar prints from any two different printers situated in different
geographical locations.
Some paper types cannot be calibrated. For all other paper types, calibration should be done in any of
the following circumstances:
●Whenever a printhead is replaced
● Whenever a new paper type is introduced that has not yet been calibrated with the current set of
printheads
● Whenever the environmental conditions (temperature and humidity) change significantly
