Printing Options
Custom Paper Sizes
The D640 supports custom paper sizes. Use the Media Eject Length
command to specify a custom paper length and the Page Width
command to specify a custom width. These dimensions are relative to
the physical paper path, so it’s possible to specify a width value larger
than the length value.
The optional custom paper tray (C5634A) has infinitely adjustable
guides, which can accommodate paper as small as 3.94 by 7.2
inches (100 by 182 mm) and as large as 11.7 by 17 inches (297 by
431.8 mm). You can use one to three custom trays in any of the tray
positions, but all custom trays installed must contain the same paper
size.
Note Paper sizes longer than 215 mm in length feed at 21 pages per minute.
Other sizes feed at 40 pages per minute.
To use custom size paper in a print job, there are several steps:
At the Control Panel
Step 1 For the custom tray location, set the PapSize tray setting to
custom.
Step 2 Set the units in the Printing Menu to mm, or 1/100".
Step 3 Set the customsize settings in the Configuration Menu to the
width and height of the paper.
The values for width and height are the width and height of the paper,
expressed in the unit values specified in the units setting. For
example, the customsize values for an 8.5 by 11 sheet would be 850
and 1100.
Step 4 Set any other settings, such as traylock, in the Configuration
Menu.
Chapter 2: Printing Options 3
In Your Print Job
Step 1 Define the Media Eject Length (the size of the paper in the
custom paper tray, left to right) by sending the PCL code:
Media Eject Length (see below).
Step 2 Define the paper width (the size of the paper in the custom
paper tray, front to back) by sending the PCL code: Select
Custom Size (see below).
Media Eject Length <ESC> & f # f/F
Sets the length of paper, as measured from the left edge to the right
edge of the paper in the custom paper tray. Command arguments
include:
Value(#) Media eject length in decipoints (1/720 inch)
Default Device dependent (should be taken from User Default
Environment)
Range 0 to the maximum supported paper length (command is
ignored for other values and the current paper length is retained)
Use this command to define the size of your paper when using the
custom paper tray, with the selection of <ESC>&l101A.
The media eject length need not be the same as the physical page
size defined by Page Size (<ESC>&l#A) or Page Length
(<ESC>&l#P). If the media eject length is shorter than the physical
page size, the physical page image will be clipped to fit the media
eject size. If the media eject length is longer than the physical page
size, the excess length will appear after the page image (to the
bottom and right of the page image so the page image is placed at
the upper left edge).
Page Width <ESC> & f # g/G
Designates the width of the logical page for a given CMI. Command
arguments include:
Value(#) Logical page width in decipoints (1/720 inch)
Default Device dependent
Range 0 to the maximum supported page width. For other values,
the command is ignored and the current paper length is retained. If a
value of 0 is received, page width is set using the following criteria (in
order of priority):
4 Chapter 2: Printing Options
• Control Panel setti ng (if applicable)
• The physical page width (if it can be sensed)
• 8.5 inches portrait, 11 inches landscape orientation.
The page width remains in effect until a new Page Width command is
received or the printer is restarted.
Note Use this command in conjunction with the Media Eject Length
command (<ESC>&f#F) to fully define a variable logical page size.
Both the Media Eject Length and Page Width commands should be
transmitted at the beginning of a page prior to any printable data.
Otherwise, when the command is sent, the current page is closed and
printed.
Select Custom Paper <ESC> & l 101A
Sets margins according to the physical size of the paper defined with
the Media Eject Length and Page Width commands.
Paper Output Trays
The D640 printer currently has two output locations: the upper tray
(standard) or the optional high capacity output stacker (HCO).
There are several differences between the upper tray and the output
stacker. The upper tray holds up to 400 sheets, stacking them facedown only. There is no offset stacking. The HCO holds up to 3000
sheets, stacked face up or face down, and it supports offset stacking.
Both output locations can use the job separation feature of the printer.
The default output is the top tray. You can specify that the jobs are
separated by a special sheet of paper, usually of a different color or
size. This feature allows effective job separation in the top tray.
Use the jobseparate setting from the Printing Menu. Alternatively, you
can give the PJL command:
@ PJL DEFAULT SEPARATOR=TRAY3
(or tray2 or tray1 or HCI or OFF)
PCL and PJL Output Commands
See Table 6 on page 17 and Table 7 on page 17 for the PCL and PJL
command definitions to select the output location and stacking
direction.

Chapter 2: Printing Options 7
Edge to Edge Printing
Typically, the D640 printer enforces a 1/6" unprintable area around
the edge of any page. This is the factory default and produces the
best looking output. There may be some cases where you don’t want
this border. The D640 supports edge-to-edge printing which allows
you to extend printing to the edge of the physical page.
Note The print quality is not consistent within 1/6" of any edge. This is
especially true for the trailing edge of the second side in duplex printing.
For this reason, Hewlett-Packard cannot guarantee print quality within
this 1/6" area. Your Hewlett-Packard warranty and service contract
does not cover service calls related to printing within this 1/6" area.
The quality and squareness of the paper determine print quality when
printing close to the physical paper edge. In general, you may
experience degraded print quality within 0.25 inches of any paper
edge. When printing in duplex you may need to compensate for
shrinkage and curl that may occur when the first side is printed.
Lighter weight and recycled papers tend to shrink more than heavier
weight paper.
For edge-to-edge printing, first turn off the clip setting in the
Configuration Menu or send the appropriate PJL command. Then, set
the logical page size to the physical page size using PCL commands.
(See example below.)
@PJL SET CLIP=OFF<EOL> ;allow printing near edges
<ESC>%-12345X
<ESC>%-12345X@PJL ENTER LANGUAGE=PCL<EOL>
<ESC>E
<ESC>&l6A ;select ledger size
<ESC>&a10W ;define page to be edge-to-edge

0x01 0x00 ;orientation is landscape
0x2F 0xD0 ;width is 0x2FD0 decipoints
0x1E 0xF0 ;height is 0x1EF0 decipoints
<ESC>&l0E ;set top margin to 0
<ESC>&a0L ;set left margin to 0
8 Chapter 2: Printing Options
If you define text to start printing at location 0,0 it will print off of the
logical page. This may or may not be on the physical page. Figure 1
describes the physical and logical page formats.
The following escape sequence allows you to define the logical page:
<ESC> & a # W[binary data]
Where # is the number of bytes of binary data following the
terminator.
The default value for # is = NA.
The range for # is = 4,10.
The binary data describes the logical page format as shown below:
Table 2 Logical Page Format
Byte 15 (MSB) 8 7 0 (LSB) Byte
0 Left Offset 1
2 Top Offset 3
4 Orientation Reserved (0) 5
6Width7
8 Height 9
Left Offset Specifies (in integer decipoints) the location of the left
edge of the logical page with respect to the left side of the physical
page in the selected viewing orientation. The range of values is
-32767 to 32767.
Top Offset Specifies (in integer decipoints) the location of the top
edge of the logical page with respect to the top edge of the physical
page in the selected viewing orientation. The range of values is
-32767 to 32767.
Orientation This is the viewing orientation of the logical page with
respect to the physical page. Values may be 0 (portrait), 1
(landscape), 2 (reverse portrait), or 3 (reverse landscape). All other
values reset the logical page definition leaving the logical page as it
was previously defined.
Reserved Byte A byte which must be present in the data stream
and must be equal to zero.
Width Logical page width is defined in decipoints. A zero width
causes the logical page definition to be ignored. The logical page may
be larger than the physical page. The range of values is 1 to 65535.
Chapter 2: Printing Options 9
Height Logical page height is defined in decipoints. A zero height
causes the logical page definition to be ignored. The logical page may
be larger than the physical page. The range of values is 1 to 65535.
Either 4 or 10 bytes of binary data defining values in the specified
range must be downloaded with this command. If more than 10 bytes
are received, the excess number is disregarded. If the number of
bytes received is less than 10 and greater than 4, the left and top
offsets are changed and the remaining bytes are ignored.
Upon receipt of a valid, 4-byte command, the current logical page
definition is updated with the new left and top offsets. The margins,
print direction, and current active position (CAP) are retained relative
to the new position of the logical page. (The only change to the
current logical page is that now it is offset relative to the physical
page.)
Upon receipt of a valid command with 10 or more bytes of binary
data, the current logical page definition is discarded and the new
definition is installed. The following actions take place with a new
definition:
The macro overlay is disabled.
l
Any current raster graphics are closed.
l
The primary and secondary fonts are set for the selected
l
orientation.
Print direction is set to zero and the orientation is set
l
appropriately.
HMI, VMI, margins, and text length are set to their PCL defaults.
l
CAP is moved to (0,0).
l
CAP becomes floating.
l
The reference point used for tiling defaults to the upper-left corner of
the current logical page. The tiles are printed based on the viewing
orientation selected.
The picture frame is defaulted to the logical page bounds and the
l
anchor point is set to the upper left corner of the logical page.
Any extra bytes specified with the command are disregarded.
l
The positions stored in the CAP stack are not changed with an
l
orientation change. Therefore, the positions are relative to the top
left corner of the current orientation.
10 Chapter 2: Printing Options
The new logical page definition remains in effect until another
l
logical page is defined, or the logical page is defaulted by receipt
of a reset, an orientation change, a page length, or a paper size
command. The current logical page definition (PCL default or
user defined) is part of the user and overlay environments. A
graphic mark will appear on the page if and only if it falls within
the printable area and the logical page boundaries. For HP-GL/2
mode, graphics must also be within the defined picture frame and
user defined window.

Working with Multiple Copies
You can print multiple copies of a document using the following
methods:
setting the printer’s control panel
l
(Copies, Mopies, and Auto-collate)
using commands in a print job
l
For more information on setting the printer’s control panel to create
multiple copies, see the
User Manual
To specify multiple copies in a print job, use the following commands:
Table 3 Commands for Multiple Copies
PJL SET COPIES = n Where n is the number of copies specified for each page of a
document. Copies are created on a page -by-pag e basis . Each pa ge is
printed n times. See illustration below.
PJL SET QTY = m Where m is the number of collated copies (mopies) spec ified for the
document. Copies are created on a document-by-document basis. A
completed document is printed m times. See illustration below.

CCITT Groups 3 and 4 Decompression
The D640 printer supports CCITT Groups 3 and 4 image
decompression, commonly used for faxing data and images. You can
send the printer these printer-specific commands and data
compressed using CCITT Groups 3 and 4. The printer decompresses
and prints the data.
Three new modes for transfer raster data are supported:
<ESC>*b#M
6 - CCITT G3 one-dimensional (modified Huffman)
l
7 - CCITT G3 two-dimensional (modified Read)
l
8 - CCITT G4 two-dimensional (modified Read)
l

The first four bytes of this command are a 32-bit unsigned integer that
specifies the number of pixels per row. If these bytes are inadvertently
transposed, the image may appear to be one long row of pixels.
Most standard PCL5 raster image commands, excluding Y offset
<ESC>*b#Y commands, work with the new printer-specific command
extensions.
Chapter 2: Printing Options 13
If possible, identify the compression method used on the data you’ll
be decompressing and printing. With this information, you can more
accurately select values for the printer-specific commands. If you
cannot identify the type of compressed data, you will have to
experiment with the commands when trying to decompress and print
the image.
You may encounter CCITT compressed data where the data is
reversed. For example, the first four bytes of the data file should
contain a value representing the width of the image in pixels per row.
A typical value might be Ox: 00 00 01 98, indicating a width of 408
pixels. If the bytes were swapped into “little endian” order, they would
appear as Ox: 01 98 00 00, which would indicate a very wide picture.
The D640 supports a resolution of 200 dpi, so images scanned at this
resolution print at their normal size.
Image Position
The decompressed image will be placed within the PCL 5 default
margins unless edge-to-edge printing is selected. Use the printerspecific edge-to-edge commands, along with the following cursor
positioning command:
<ESC>*p0x0Y cursor position at 0, 0
Table 4 Image Position

LaserJet Compatibility
The D640 printer is unique and different from the Hewlett-Packard
LaserJet family of printers in general, and from the LaserJet “Si”
series in particular. While these two printer families share the same
printer language (PCL and PJL), there are a number of physical
differences to their hardware.
Hewlett-Packard has included features in the D640 printer to make it
behave like a LaserJet 4Si, so your print jobs turn out like you would
expect them to if you were printing to a 4Si. In many instances these
features also provide compatibility with other LaserJet products such
as the IIISi and/or 5Si.
This section covers the compatibility features associated with PCL
commands.
Paper Input
The D640 has three paper input trays, while the LaserJet 4Si has two,
and the LaserJet5Si has three.
The IIISi and 4Si printers have a high-capacity input (HCI) unit
available as an option. Jobs set up for this environment use the PCL
<ESC>&l4H command to se lect the HCI. The sa me command sele cts
tray2 on the D640.
HCI selection compatibility is provided through the HCI-Alias Control
Panel setting. HCI-Alias enables paper selection compatibility
between a LaserJet IIISi (or 4Si) with an HCI and a D640 with an HCI.
With HCI-Alias = tray2 (normally the LaserJet 4Si’s high capacity
input) the PCL command <ESC>&l4H causes the D640 to pick paper
from the HCI. You can also set HCI-Alias = HCI to pick paper from
tray1, tray2, tray3, or the HCI in response to the PCL commands
shown in Table 5.
Chapter 2: Printing Options 15
Example Configuration
LaserJet IIISi / 4Si
UPPER TRAY contains paper for job separation.
l
HCI TRAY contains white paper.
l
This configuration provides 500 sheets in the upper tray
(<ESC>&l1H), and 1500 sheets in the HCI tray (<ESC>&l4H). To
match this configuration on the D640, set up the D640 as follows:
TRAY1 contains paper for job separation.
l
HCI contains white paper.
l
Set HCI-Alias = tray2.
l
This configuration provides 500 sheets in tray1 (<ESC>&l1H), and
3000 sheets in the HCI (<ESC>&l4H). You could also load paper for
job separation in tray2 and tray3 to increase capacity to 1500 sheets.
If HCI-Alias is set to HCI, the values shown below in Table 5 are
correct. If HCI-Alias is set to tray2, then you can send a job to either a
4Si or a D640.

You can also set the default paper tray (used if there is no paper size
or paper source command embedded in the print job) from the
Control Panel or via PJL commands. Use the intray setting in the
Printing Menu, or the PJL command:
@PJL SET MEDIASOURCE=TRAY1
(or TRAY2 or TRAY3 or HCI)

Internal Fonts
Each of th e D640 inte rnal f onts is alm ost id entica l to t hose used i n the
LaserJet 4Si. Due to advances in font technology since the
development of the 4Si, some typefaces, treatments, and symbol sets
are slightly different. (For example, if you print a very large question
mark on each printer, you may notice differences in the shape.)
Each of the D640 printer’s 56 virtual font cartridges is almost identical
to the corresponding font cartridge sold for the LaserJet IIISi and 4Si
printers.
See Chapter 6 for more information about D640 fonts and virtual font
cartridges.

About TIFF Images
The D640 printer supports TIFF emulation which enables your printer
to recognize and print bi-level, monochrome TIFF images. Previously,
TIFF images had to be part of a larger PCL or PostScript (PS)
document to be printed.
TIFF support for the D640 printer conforms to the specifications
described in
1992. The information in this chapter assumes you are familiar with
TIFF Revision 6.0
The D640 printer supports relevant parts of Baseline TIFF and
selected elements of Extended TIFF. There are no private fields or
values required by the printer.
TIFF Revision 6.0
published by Aldus Corporation, June
.
Note The TIFF standard does not contain any elements to indicate the
termination of data. Therefore, termination of a TIFF file must be
indicated by PJL universal escape sequences or the printer’s I/O
timeout configuration.
Printing TIFF Images
TIFF images can be printed using the following methods:
l setting the printer’s control panel to recognize TIFF files
(Emulation = TIFF or Auto). Auto is the recommended setting if
you print files using more than one protocol (such as PCL or PS).
l using commands in a print job
Chapter 3: Working with TIFF Images 19
Using the Control Panel
On the printer’s control panel, you can explicitly select TIFF
emulation. For details, see the
User Manual
.
When TIFF emulation is set, the following data items are valid:
A new TIFF file, starting with a 4-byte sequence $49492A00 or
l
$4D4D002A
PJL commands
l
Any other type of data is treated as an error.
On the printer’s control panel, you can also use the Auto emulation
setting to implicitly recognize TIFF files.
If Auto emulation is set, the printer recognizes either of the following
sequences as valid TIFF file headers and enters TIFF emulation
mode automatically, if this sequence is at the start of the print job.
$49492A00 or $4D4D002A
l
Using Commands in a Print Job
In addition to control panel settings, TIFF protocol can be selected by
the PJL command:
@PJL ENTER LANGUAGE = TIFF
The following is a sample print job for a TIFF file:
<ESC>%-12345X@PJL JOB NAME="Sample.tif"<LF>
<ESC>%-12345X@PJL SET CLIP=OFF<LF>
<ESC>%-12345X@PJL ENTER LANGUAGE=TIFF<LF>

20 Chapter 3: Working with TIFF Images
General Rules
The following are some general rules to describe how the D640
printer processes TIFF data.
Each TIFF file is a self-contained unit, made up of one or more
l
sub-files. Each sub-file describes a single rectangular image. The
image may be a complete page, or it may be a part of a page.
During TIFF emulation, the printer cannot switch into any other
protocol, except at the boundaries of individual TIFF files.
If a TIFF image contains multiple sub-files, the images contained
l
in the sub-files are placed on separate pages in the order the
sub-files appear in the TIFF data stream.
If TIFF is the selected protocol:
l
• Images are placed with respect to the physical page, with zero
margins.
• If a sub-file doesn’t have positioning information, the image is
placed at the edge of the page.
• If a sub-file has positioning information, the commands are
interpreted as absolute displacements from the edge of the
physical page.
• The Clip setting for the document determines if the image is
printed to the edge of the page.
This can be a common
situation. TIFF documents are often created to take up the
entire page. To prevent
clipping of the image
when you print, make
sure
Clip = Off is set in the
Configuration menu.

This can be a common

Clip = On Clip = Off
Chapter 3: Working with TIFF Images 21
TIFF was designed as a file structure for random-access devices.
l
When used as a printer protocol, HP recommends the following
ordering restrictions apply to allow sequential processing of the
data. These include:
• Offset values should be greater than the file position of the
offset. For example, If an offset resides at file position A within
the TIFF data, its value should be greater than A.
• Within a file, all tag fields pertinent to the image should precede
the image data.
• The ordering of components within each sub-file should be:
- Image file directory
- Data values identified by directory entry offsets
- Image data.
See page 23 for some example TIFF structures.
22 Chapter 3: Working with TIFF Images
Preferred structure of a TIFF file: In Example 1 and Example 2, all the image file directories
occur early in the file. This is a good structure for TIFF files sent to the D640 printer.

Errors
Errors in the TIFF file header or in directory offset values are
considered major errors. The remainder of the TIFF file is ignored and
the print job is abandoned.
For other errors, the processing of the current sub-file continues, but
no image is printed. Subsequent sub-files are processed normally .
The following are the main categories of errors:
Absence of mandatory TIFF fields (directory entries)
l
Duplicate occurrences of tags in one directory
l
Wrong type for a significant TIFF field
l
Wrong number of values for a significant TIFF field
l
Value out of range for a significant TIFF field
l
Offset values less than the file position of the offset (for a
l
significant TIFF field)
If a TIFF field is not significant for the printer, its Type, Number, and
Value are not checked for correctness.
The TIFF specifications (described in
fields to appear in ascending tag order. The D640 printer does not
enforce this requirement.
Note Y ou can use the error report setting on the D640 printer to print a report
of TIFF errors within a print job. See the
information.
