2.2
Special Notes
4 HP DeskJets were designed in series - the printer’s internal firmware will usually report the
series name, rather than the specific product name. All printers in a series will behave as
the base model. For example, the HP DeskJet 810C Series printers were sold under the
name of the HP DeskJet 810C, HP DeskJet 812C, and the HP DeskJet 815C. All three
printer models have the same internal firmware, reporting the printer as a HP DeskJet
810C.
Note that the HP DeskJet 895Cse and HP DeskJet 895Cxi are both part of the HP DeskJet 895C Series family and are NOT derived from the HP DeskJet 890C Series.
4 If a command is not covered in this guide, it is either obsolete or Hewlett-Packard proprietary information. No further information on these unsupported or proprietary commands
is available.
4 In the HP PCL escape sequences within this manual, the letter “ell” (l) is represented by a
script character (l ) to differentiate between the “ell” and the character 1 (one). Where
spaces have been added to commands for readability, those spaces must not be included
in your code.
4 Specifications on the ink cartridges (including the HP Photo Cartridge) are not available this is Hewlett-Packard proprietary information and will not be provided.
2.2.1
Special Note - HP DeskJet 710C, 720C and 820C Series printers
4 The HP DeskJet 710C, 720C, and 820C Series printers are “Windows” printers. These
printers will not function from a DOS-only environment. However, they will work when
accessed from a DOS box within Windows 3.1x, 95, 98.
For clarity, these printers are not included in the printer tables in this guide. If you wish to
send PCL commands to these printers, use the HP DeskJet 660C Series printers as your
guide in the tables.

The Command Description Page
A
Since some commands are not recognized by all HP DeskJet printers, or some family members do not recognize all options for a particular command, it is necessary to indicate which
printers do respond to each command, and how each printer treats each command option.
4.0.3
Command Name
B
The Command Name is the name by which each command is referred to within the text of this
guide, and by which the command is referenced in the index.

4.0.4
Escape Sequence
C
This is the ASCII text version of the binary string, which causes the command to be invoked.
The pound sign ("#") is used to represent where one of the command options, which are listed
following the Command Summary, would be inserted.
4.0.5
Command Summary
D
A brief description of the purpose of a command is given. The Command Summary can be
used to determine quickly if a particular command will perform the overall task you desire.
4.0.6
Command Usage Table
E
The Command Usage Table provides a quick key for the application of the available command
options for each printer command. The column labeled "#Value" lists all options (also referred
to as command parameters) for the command being discussed. The group of columns labeled
with the model numbers of the HP DeskJet printers indicates which printers recognize each
command option. The column labeled "Effect" briefly describes what result the use of each
command option will have. The Command Usage Table is designed to let you quickly determine if a particular command and a selected command option will be recognized by your target printer, and what the effect of using that command and command option will be. The
detailed command description can be carefully studied to gain a thorough understanding of
the command once you determine if it is the one you want to use.
4.0.7
Command Options
F
All command options for a command are listed in the column of the Command Usage Table,
which is labeled "Value". You should note that even though a particular member of the HP
DeskJet printer family is indicated as recognizing a command, that printer may not recognize,
and therefore not respond to, all listed command options.
4.0.8
Command Option Recognition Grid
G
This section of the table serves to quickly indicate which HP DeskJet printer models will recognize and respond to a particular command option. If a check mark ("4") appears under a particular printer model in the row for a command option, that printer will recognize the option. If
there is no check mark for a command option under a particular printer model number, that
printer will not recognize or respond to that command option. If a command is used with an
option the printer does not recognize, the results you obtain on your print media will be unpredictable; your printed page may not appear as you expect.
4.0.9
Effect of Command Options
H
The result of using the command with a given command option is briefly described. A detailed
description of the impact of the command and its options are provided in the detailed command description, which follows the Command Usage Table.

Important Point
Where a blue exclamation point appears, special information that you should keep in mind is
presented. (As a side note, if you print this document on a monochrome printer, the exclamation point will appear a dark gray.) This information may be of a cautionary nature, or it may
be included in this emphasized format to point out special cases, which may apply for a command. Any information noted in these areas should be read carefully before you use the associated command.

Introduction to HP PCL

Introduction to HP PCL
5.1
History of HP PCL Printer Language
Hewlett-Packard created the HP PCL Printer Language to provide an economical and efficient
way for application programs to control a range of printer features across a number of printing
devices. HP has evolved both the definition and implementations of the HP PCL printer language to provide the optimal price and performance balance. HP PCL 3 continues to lead with
enhancements to the HP PCL printer language in order to deliver powerful technology
advances.
The HP PCL printer language commands are compact escape sequence codes that are
embedded in the print job data stream. This approach minimized both data transmission and
command decode overhead. HP PCL printer language formatters and fonts are designed to
quickly translate application output into high-quality, device-specific, raster print images.
HP PCL printer language commonality from HP printer to HP printer helps to minimize printer
support problems and protect HP printer customer investment in applications and printer driver
software.
5.1.1
What are Printer Commands?
HP PCL language printer commands provide access to printer features. There are two general types of HP PCL language commands:
4 Control codes
4 HP PCL commands
5.1.2
Control Codes
A control code is a character that initiates a printer function, for example Carriage Return
(CR), Line Feed (LF), Form Feed (FF), etc.
5.1.3
HP PCL Commands
HP PCL commands provide access to the printer's HP PCL control structure. The HP PCL
structure controls all of the printer's features.
HP PCL printer commands consist of two or more characters. The first character is always the
ASCII escape character, identified by Esc. Esc is a special control code, which identifies the
subsequent string of characters as a printer command. As the printer monitors incoming data
from a computer, it is "looking" for this character. When this character appears, the printer
reads it and the subsequent string of characters as a command to be performed and not as
data to be printed.
!
HP PCL printer commands are also referred to as escape sequences. The two terms are
used interchangeably throughout this manual.
HP DeskJet 600, 700, 800, 900 & HP 2000 Series PCL Developer’s Guide
13
Introduction to HP PCL
Once an HP PCL command sets a parameter, that parameter will remain set until that HP PCL
command is repeated with a new value, the printer is reset to its user default environment, or
another command makes a change. For example, if you send the printer a command to set
line spacing to 3 lines/inch, each page will print 3 lines/inch until the printer receives a Line
Spacing or VMI command or the printer is reset.
5.2
Syntax of Escape Sequences
There are two forms of HP PCL escape sequences: two-character escape sequences and
parameterized escape sequences.
5.2.1
Two-Character Escape Sequences
Two-character escape sequences have the following form:
Esc X
Where "X" is a character that defines the operation to be performed. (Note, "X" may be any
character from the ASCII table within the range 48-126 decimal ["0" through "~"]).
Following are examples of two- character escape sequences:
5.2.2
Esc E
a two-character escape sequence used for resetting the printer.
Esc 9
a two-character escape sequence used for resetting the left and right margins.
Parameterized Escape Sequences
Parameterized escape sequences have the following form:
Esc X y # z1 # z2 # z3 … # Zn[data]
Where y, #, zi (z1, z2, z3… ) and [data] may be optional, depending on the command.
X Parameterized Character - A character from the ASCII table within the range 33-47 decimal ("!" through "/") indicating that the escape sequence is parameterized.
y Group Character - A character from the ASCII table within the range 96-126 decimal (" ' "
through "~") which specifies the group type of control being performed.
# Value Field - A group of characters specifying a numeric value. The numeric value is represented as an ASCII string of characters within the range 48-57 decimal ("0" through "9") that
may be preceded by a + or - sign and may contain a fractional portion indicated by the digits
after a decimal point (.). Numeric value fields are within the range -32767 to 32767. If an
escape sequence requires a value field and a value is not specified, a value of zero is
assumed.

Introduction to HP PCL
zi Parameter Character - Any character from the ASCII table within the range 96-126 decimal (" " " through "~"). This character specifies the parameter to which the previous value
field applies. This character is used when combining escape sequences.
Zn Termination Character - Any character from the ASCII table within the range 64-96 decimal ("@" through "~”). This character specifies the parameter to which the previous value field
applies. This character terminates the escape sequence and is always in the form of a capital
letter, such as A, M, T, etc.
[Data] Binary Data is eight-bit data (for example, graphics data, downloaded fonts, etc.). The
number of bytes of binary data is specified by the value field of the escape sequence. Binary
data immediately follows the terminating character of the escape sequence.
Following is an example of an escape sequence with a termination character and no parameter character. This escape sequence performs a single function of logical page orientation in
landscape mode.

4 Some escape sequences shown in this manual contain spaces between characters for
clarity. Do not include these spaces when using escape sequences.
4 Also, in the escape sequence a script "l” is used to indicate a lower case "l" for clarity.
The following is an example of two escape sequences, each of which perform one function:
the first sets the logical page orientation to Portrait Mode, and the second sets the page size to
8 ½ x 11 inches.
Esc & l 0 O and Esc & l 2 A
These two escape sequences can be combined into one escape sequence as follows:

Notice that the "Esc" and the "&l" are dropped from the second printer command when they
are combined. Also, the upper-case "O" that terminated the first command becomes a lowercase "o" parameter character when these commands are combined.
Use these three rules to combine and shorten printer commands:
4 The first two characters after "Esc" (the parameterized and group character) must be the
same in all of the commands that will be combined. In the example above, these are "&"
and "l".
4 All alphabetical characters within the combined printer command will be lower-case,
except the final letter, which is always upper-case. In the combined example above, "O"
becomes "o". The final character in the printer command must always be upper-case to
let the printer know that the command is complete.
4 The printer commands are performed in the order that they are combined (from left to
right). Be sure to combine commands in the order that they are to be performed.

The Page
6.1
Logical Page, Physical Page
The HP PCL printer language distinguishes between the physical page and the logical page.
The physical page is the actual sheet of paper. Its size is determined by the size of the media
installed in the printer. The logical page defines the addressable area in which the cursor can
be positioned.
CAP (Current Active Position) refers to the "cursor" position on the logical page, similar to the
cursor used on most computer terminals. The CAP location on the logical page is the next
position where a character will be placed. CAP cannot be moved outside of the logical page
bounds. The figure below shows the layout of the logical page.

The Page
6.2
Page Layout
Referring to the previous figure, each page passed through the printer has a number of components. Text printing is normally limited to a specific printable area within the logical page
known as the text area. The text area is entirely contained by the logical page, but may be
smaller because of margins. There are unprintable regions along the outside edges and bottom of each sheet of print media. If printing is attempted outside the printable area at the bottom of the sheet, data may be printed on the following sheet. If printing is attempted in the
unprintable regions, formatting or data may be lost.
The perforation skip zone extends from the bottom of the text area on one page to the top of
the text area on the next page. When the Perforation Skip Mode is turned ON, a Line Feed
that would normally move CAP into the bottom margin of the current page instead moves CAP
to the top of the text area on the next page. If the Perforation Skip Mode is turned OFF, a Line
Feed that would move CAP into the bottom margin is allowed. If text printing is attempted
within the unprintable region at the bottom of the page, a hardware page break occurs, the text
is printed on the next sheet of print media, and then a software page break occurs. The result
is an unplanned, extra page, which contains only that portion of the text which invaded the
unprintable region.
Allow ½ inch at the bottom of the page. This extra ½ inch can mean a loss of 3 lines. For
example, on an 11 inch page, the full-page length is 66 lines (6 lines per inch). However, the
effective page length is 10 ½ inches, or 63 lines.
6.2.1
Current Active Position (CAP)
CAP is the position at which the next character will be printed on the page. This position can
be moved to different points on the logical page using the cursor positioning commands. CAP
cannot be moved outside the bounds of the logical page, except when moving to another logical page.
CAP position (0,0) is at the left edge of the logical page at the current top margin position.
Since the top margin can be changed using a printer command, the physical location of the
18

point (0,0) may change. The point (0,0) then, does not necessarily equate to the top of the
paper.

6.2.2
CAP Reference Point
The first line starts at the (0,0) coordinate. CAP starts at (X,Y), where X= the left margin setting, and Y= the top margin setting. CAP is moved the distance of the Horizontal Motion Index
to the right after printing a character and one dot row down after printing graphics. The physical location of the (X,Y) coordinate can change due to the size of the first printed character.
Characters are placed with their reference points at CAP. The reference point is on the character baseline, a horizontal line just under the bottom of the non-descending characters. This
means that if the top margin is at the top of the logical page, text cannot be printed at (0,0)
because most of the character would be above the top edge of the page.
Graphics, however, can be printed at (0,0) because they do not move above CAP. Graphics
begin at the vertical level specified by CAP and then move downward on the page from that
point.

The Print Environment
7.0
The Print Environment
The group of all the printer's current feature settings is collectively referred to as the print environment. Default settings refer to the settings the printer uses unless printer commands are
used to select other settings. Default settings are settings that are programmed into the printer
at the factory.
Each time a job is printed, some of the printer's feature settings may be changed from their
default values to produce a desired output for that job. After the job has printed, the job specific feature settings are no longer needed, since the next job will likely have different output
requirements. The next job should clear all previous job settings by performing a reset. This
allows a job to start with the default settings as a base and vary only those settings that are
needed. Returning to the default environment at the beginning of each print job eliminates the
need for setting every feature each time a job is run.
!
20
Starting your print job with the Reset command (Esc E) is the recommended procedure,
since the escape sequence resets all programmable features to their default values.

Merged Text and Graphics
8.0
Merged Text and Graphics
The process for merging text and graphics with the HP DeskJet 600/800/900 & HP 2000
Series printers in both portrait and landscape orientation is the same as the landscape orientation method for the HP DeskJet 520, 540, 550C, and 560C Series printers, described in the
HP DeskJet 500 Series Technical Reference Guide. The HP DeskJet 600/800/900 & HP
2000 Series printers are capable of buffering an entire page of text in either portrait or landscape orientation. This capability dramatically simplifies the procedure for merging text and
graphics.
As with the landscape orientation method for the HP DeskJet 520, 540, 550C, and 560C
Series printers, when merging text and graphics for the HP DeskJet 600/800/900 & HP 2000
Series printers, the text for the entire page is first sent to the printer (without a Form Feed command), where it is stored in the printer’s formatting buffer. Following the transmission of the
text, the CAP is moved to the graphics starting position with cursor positioning commands.
The graphics data for the page is then sent to the printer, and the page is printed as the graphics data is processed by the printer firmware.
It is important to note that once graphics data has been received for any particular raster row
on the page, no text can be printed at that or any earlier position. You should not attempt to
alter this procedure, for instance by sending a partial page of text, a partial page of graphics,
then resuming with text transmission. Even if you do not violate the rule of sending text for a
line (or preceding a line) where graphics data has been received, attempting to intermix the
transmission of text and graphics data for a given page will render unpredictable results. Send
all text for an entire page, then send all graphics data.
Follow the last of the graphics data with a Form Feed command, which will cause any remaining text data for the page to be printed, then proceed to the next page.
!
If you are modifying an existing DeskJet 500 Series printer driver, which has correctly
implemented the merging of text and graphics in the past, to include other features for the
HP DeskJet 600/800/900 & HP 2000 Series printers, you need not re-write your old driver.
Add support for the new features to existing code, being careful to consider the impact of
old, obsolete commands. However, if you are just beginning development, or you intend to
add merged text and graphics capabilities for the HP DeskJet 600/800/900 & HP 2000
Series printers, you should begin with the algorithm provided above.
Be aware that highly complex pages, those with numerous font changes or cursor repositioning accompanying dense and complex graphics, may cause overflow condition with the printer
buffer. If you encounter this problem, you may be able to remove some of the font or position
changes in order to reduce the complexity of the page description.

Programming Hints
9.0
Programming Hints
The following are overall guidelines to keep in mind when programming with HP PCL printer
language commands.
9.0.1
Follow Specifications
Follow the specifications for HP PCL printer language commands as described in this guide.
Do not rely upon undocumented workarounds. For example, the HP DeskJet 500 Series printers do not allow a negative vertical cursor movement of more than 1/3 inch. While it is possible to create a workaround, the solution may produce undesirable results, as the printer papermovement hardware is not designed to provide negative paper motion. Additionally, the
homemade solution that works today may not work with future printer models.
9.0.2
Leverage from Previous Programs
If you have previously used HP PCL commands to create printer programs, you may be able
use most of those same commands for the HP DeskJet 600/800/900 & HP 2000 Series printers. This is especially true if you have programmed for other HP DeskJet printers. Reusing
previously developed code can save you a significant amount of time since you do not have to
start a development effort from scratch.
When leveraging from previous programs, keep in mind that the HP DeskJet 600/800/900 &
HP 2000 Series printers have a number of important differences from the HP LaserJet family
printer.
4 HP DeskJet 600/800/900 & HP 2000 Series printers are line oriented, whereas HP LaserJet printers are page oriented. The HP LaserJet printers format the entire page in internal
memory and then the entire page is printed, whereas the HP DeskJet 600/800/900 & HP
2000 Series printers format and print consecutive horizontal lines of text or rows of graphics of the page content, one after another, until the entire page has been printed.
4 HP LaserJet printers have full-page printing capability and can position the cursor anywhere on the page. HP DeskJet 600/800/900 & HP 2000 Series printers format from the
top of the page to the bottom.
4 Generally, HP DeskJet 600/800/900 & HP 2000 Series printer commands sent to the HP
LaserJet printer will provide the expected printing results, but may not work as efficiently.
Not all HP DeskJet 600/800/900 & HP 2000 Series commands will work with HP LaserJet
printers.
9.0.3
Priority of Feature Set Commands
Printer features for the HP DeskJet 600/800/900 & HP 2000 Series printers are controlled by
escape sequences and control codes. Software application commands override default settings. However, when the printer is reset, either by turning the printer off and then on again or
by sending the Reset escape sequence (Esc E), the printer returns to the default settings.
22
HP DeskJet 600, 700, 800, 900 & HP 2000 Series PCL Developer’s Guide
Programming Hints
9.0.4
Priority of Commands
There are no finite rules when it comes to structuring your overall program. In general, start by
setting the print environment with the printer control commands, such as Reset, Selecting the
Media Source, and so on.
It is almost always advisable to start and end your program with the reset command (Esc E).
This clears the printer environment and places your program back to the default settings. An
exception to this general rule is when the printer settings are intended to carry across a multicomponent print job.
Where specified in this manual, pay close attention to the order of commands. For example,
raster graphics commands should be sent to the printer in the following order:
4
4
4
4
4
4
4
9.0.5
End Raster Graphics
Raster Graphics Resolution
Raster Graphics Width
Raster Graphics Compression Method
Start Raster Graphics
Transfer Raster Graphics Row(s) with or without Relative Vertical Pixel Movement
End Raster Graphics
Time Savers
The following list provides some helpful hints to make your program more efficient:
4 You do not need to specify leading and trailing zeroes. The HP DeskJet 600/800/900 &
HP 2000 Series printers will compensate if you do not include zeros that occur at the end
of an escape sequence. For example, if you want to specify 10 pitch during a font selection sequence, simply specify 10, rather than 0010.00.
4 Group printer control commands at the beginning of a print job. If a number of consecutive pages within a job have the same format (such as margins, HMI, VMI, etc.), the associated page formatting commands only need to be set once for that group of pages.
4 Combine escape sequences where possible. Shortening commands improves throughput. For example, instead of sending the Page Length command (Esc & l # P) and the
Top Margin command (Esc & l # E) separately, send them as one parameterized escape
sequence (Esc & l # p # E). Follow the guidelines for parameterized escape sequences,
which are described earlier in this chapter.
4 Minimize escape sequences where possible. For example, if you wish to move the cursor
two inches down the page, use one cursor movement command, rather than move the
cursor by decipoints or dots a number of times.
4 You do not need to send a request to load paper. However, you do need to specify envelope size and send a Media Source command to load envelopes.
4 Avoid using tabs to move the cursor across the page. Using tabs may make you dependent upon the current font pitch. Instead, use cursor positioning commands.

23
Programming Hints
4 Avoid using a Start Raster Graphics and End Raster Graphics command on every line.
Use these commands at the beginning and end of the graphics image.
4 When setting the raster graphics width, calculate the widest point of the raster image. Use
this value to set the width once for the entire raster graphics image.
4 Avoid setting top margin or text length to values outside of the printable area. This may
cause data loss.
When using both the top margin and text length commands, the top margin command should
be sent before the text length command

HP PCL Commands
10.0
10.1
HP PCL Commands
Control Codes and Special Character Codes
The following commands initiate printer control functions:
10.1.1
Escape
Provides supplementary control of printer functions. The escape character itself is a prefix for
the string of one or more characters that follow. Once an escape character is received by the
printer, normal text processing is suspended, and the contents of the print data stream are
interpreted as a printer command, until the command has been activated by a command termination character, or the escape sequence has been determined to be invalid.
10.2
Testing Commands
Transparent Data Mode, and Display Functions modes (both of them) are used for testing purposes, to allow you to print the actual setup strings rather than having HP PCL actually interpret and execute them.
You can use either Print Modes -or- the Display Functions Mode On and Off commands whichever is more intuitive in your programming environment.

!
This command must use a capital “D” as a terminator.
Except when changing the left margin causes positive horizontal CAP movement, when
underlining is enabled, each printed character or any positive horizontal motion (e.g., spaces,
CAP moves) is automatically underlined.
Once enabled, underline remains enabled until explicitly disabled. The default state is underline disabled.
A single underline is produced if double underline is invoked but unavailable, as in the case of
the DeskJet 850/870/890 Series printers.
When fixed location underlining is enabled, the underline is drawn a fixed, device-dependent
distance below the baseline. When floating location underlining is enabled, the greatest underline distance specified in all of the fonts printed on the current line determines where the
underline is positioned. The underline distance and height is defined in the font descriptor.
In the HP DeskJet implementation of “floating” underline, each font defines the thickness of
the underline character and its position relative to the baseline.

Defines the action that occurs when a line of text reaches the right margin.
When end-of-line wrap is enabled, a character or space that would move the CAP to the right
of the right margin causes a CR-LF to be executed (prior to the printing of the character or
space).
When end-of-line wrap is disabled, a character or space that would move CAP to the right of
the right margin is not printed, and CAP is set to the right margin.

Performs a reset on the printer (this is NOT a hardware reset). The reset performs the following:
Prints all data received before the reset.

“Floats” CAP.
Resets all programmable features to their user default values.
Deletes temporary fonts.
Does not delete downloaded permanent features.
Resets the color palette to black and white.
Esc E has no effect on I/O and causes no disruption in host-to-peripheral communication. The
printer remains on-line and no data is lost.
Esc E should be the first command received at the beginning of a job (e.g., before font download) to establish default conditions; and it should be the last command at the end of a job to
leave the machine in the user default state and clear any partially composed pages.
Esc E “floats” CAP on the current page if no printable data has been received; otherwise it
ejects the current page and “floats” CAP on the next page.
CAP is floating prior to printable characters, or commands affecting CAP. (Commands affecting CAP are ASCII data, LF, CAP moves, space, etc.). Commands affecting top and left margins, line spacing, page length, and orientation can change CAP while it is floating.
CAP is fixed following printable characters or commands affecting CAP. CAP is fixed to the left
margin and top margin plus 3/4 VMI upon receipt of printable characters or raster graphics
commands that explicitly move CAP fix it at the specified location. Commands changing the
top and left margins or line spacing cannot affect a fixed CAP; page length or orientation commands eject the page, moving CAP to the top-of-form on the subsequent page. If no printable
data is received, page length and orientation commands eject the page only if the device cannot move the paper back to the top of form. The intent is to not eject unnecessary blank pages.
Since control panel settings can override the factory defaults, Esc E uses the control panel
settings as the default values.
The SPACE character is not considered a printable character with respect to CAP.

Determines whether black optimization is performed to make process black (composite
black—composed of color inks) appear more black.
When composite black is constructed by setting all the bits in the CMY color planes, the resulting color may not be isotonic. Gray balancing removes some dots to neutralize the hue shift.
Esc E resets Gray Balance to the device-dependent default.

The default for the HP DeskJet 550C is 2 (disable gray balancing).
The defaults for the HP DeskJet 540 and HP DeskJet 600 printers are Print Mode and
Media Type dependent - as shown in the following table. Other HP DeskJet printers do
not require gray balancing, as the gray balance function is built into the Media Type/Print

EFFECT
Sets a minimum dry time between pages to ensure that a previous page dries before the next
page is dropped on top of it.
The time required for ink to dry depends on media, print modes, and environment (temperature and humidity). For example, transparencies may need over 10 minutes in an unheated,
damp environment.
Esc E resets the dry timer to the default value of 0.
!
The Dry Timer function has been incorporated into the Media Type/Print Quality command
combination. The parameters specified for those commands determine the Dry Timer setting. Although some HP DeskJet 600/800/900 & HP 2000 Series printers will respond to
this command, the command is considered obsolete. Dependence on the command
should be removed from your application.

HP PCL Commands
The value field establishes the number of units per inch used in the following commands.
These commands formerly used a device’s dot-per-inch resolution as the unit of measure.
Printers that do not support this command still use dots as their unit of measure for these commands.

Move CAP Vertical (PCL Units) - Esc * p # Y
Move CAP Horizontal (PCL Units) - Esc * p # X
Vertical Rectangle Size (PCL Units) - Esc * c # B

In addition, since the current unit of measure setting affects how CAP movement values are
rounded, it also affects the result of the following commands:
4
4
4
4
Move CAP Horizontal (Columns) - Esc & a # C
Horizontal Tab - <HT>
Space - <SP>
Backspace - <BS>
This command affects only the start of characters and PCL Unit commands. This may cause
character spacing to be different on a 600 dpi printer vs. a 300 dpi printer, or on a 300 dpi
printer that supports this command vs. a 300 dpi printer that does not. To get the same character placement on both printer, the unit of measure should be set to 300 and HMI command
(Esc & k # H) should be sent after font selection has occurred.
This command does not affect binary raster data (bitmap fonts, raster graphics, patterns).
A control panel reset or Esc E defaults the measuring unit. Since the unit of measure is part of
the user environment, it is saved and restored whenever a macro is called or an overlay
invoked, but is defaulted when the user environment is established for an overlay.
Bitmap and scalable fonts must retain their initial metric information. Conversion to the current
selected unit must use the original units to avoid cumulative errors due to successive rounding.
Out-of-range values are mapped to the supported value with the minimum relative error.

This should be as complete a self-test as the product is capable of performing. If no error is
detected, the printer will remain on-line. If an error is detected, the printer will go to the off-line
state.
In general, this command should not be used in an application. It is intended as a diagnostic
tool for developers and support staff. The HP DeskJet 600/800/900 & HP 2000 Series printers
provide several diagnostic print outs that are user-accessible via the printer front panel.

Reverse Landscape
Defines the position of the logical page and the default direction of text printing with respect to
the physical page.
If the printer has received printable data, an orientation change ejects the current page and
opens another page in the new orientation. Since this command ejects the page, it cannot be
used to change text orientation within a page. The command is ignored if the new orientation
and the current orientation are the same.
This command does not affect graphics.
This command has the following effects:
4 Prints all data received before the command.
4 Executes a formfeed and carriage return.
4 Sets the following to their user defaults:
- logical page
- print direction
- page length
- text length
- top margin, left margin, right margin
- HMI and VMI
This command should be sent at the beginning of a page because it ejects a page containing
printable data. Since this command defaults the above features, it should be followed by commands that set any desired non-default values.
This command affects only text orientation - not raster graphics orientation. For example, if orientation is changed from portrait to landscape, graphics will continue to print in portrait. This
can result in clipping if CAP is not positioned to take this into account.

Designates the width of columns used for horizontal movement calculations. In the vertical text
path direction, designates the height of rows used for inter-character movement calculations.
HMI defaults to the invoked font’s space character when any of the font’s characteristics (orientation, character set, pitch, etc.) are changed, when switching between primary and secondary fonts with <SI> and <SO>.
For fixed pitch fonts, HMI affects all printable characters, including the space and backspace
characters. For proportionally spaced fonts, HMI may affect only the space character: if the
space character glyph exists, CAP moves the width of the space character; otherwise CAP
moves according to the HMI.
For multiple fixed-pitch fonts, the HMI directly affects the nominal (full width) space of the font.
Other spacings are scaled linearly according to the current HMI value, i.e., the character
widths are multiplied by the ratio of the HMI to the nominal width.
In the vertical text path direction mode, the HMI defaults to the height (x 112%) of the font. In
fixed-pitched or multiple-fixed-pitched fonts, the HMI takes on the height (x 112%) of the fixedpitch font.
For proportionally-spaced fonts, the HMI may affect only the space character. If the space
character glyph exists, CAP moves the height (x 112%) of the space character. Otherwise the
CAP moves according to the HMI.

Sets the vertical spacing between lines of print (the vertical distance CAP will move for a linefeed in horizontal text path mode and the horizontal distance the CAP will move for a linefeed
in the vertical text path mode.
This command performs the same functions as Line Spacing (Esc & l # D), except the measurement interval is in 1/48-inch increments instead of lines per inch (lpi). Both commands set
linefeed spacing. To convert lpi to VMI:
VMI = 48.0/ lpi
If the Page Length (Esc & l # P) command follows an VMI change, physical page size is
recalculated. Depending on the VMI modification, the printer may request a different page
size.

EFFECT
Top margin is set to specified
number of lines at the current

Specifies the distance between the top of the logical page and the top of the text area.
The top margin is specified in lines whose spacing is determined by the current line spacing.
This command is ignored if the current line spacing is 0, or if a value beyond the current logical
page length is received.
CAP is not moved if it is below the new top margin. If CAP is above the new top margin, CAP
is placed at the baseline of the first row of characters. This position, called top of form, is calculated as follows: top of form = top margin in inches + (.75 x VMI in inches)
The first line of the logical page is always line 0. The vertical position of the first line of print on
the logical page is at top of form as defined above.
The top margin represents a physical position: once the top margin is set, it is unaffected by
subsequent changes in line spacing.
!
Since this command defaults text length, it should precede the Text Length (Esc & l # F)
command.
HP DeskJet printers default to 1/2” with perforation skip mode on, and 0” with perforation
skip mode off.

HP PCL Commands
10.9
Horizontal Positioning Commands
The following commands provide for cursor movement on the horizontal axis.
10.9.1
Backspace
<BS>
Moves CAP one character position backwards on the current line.
For horizontal text path direction, no action occurs if CAP is already at the left margin. If the
CAP is to the left of the left margin (via one of the Move CAP commands), <BS> functions as if
the left margin were column 0, the logical page left boundary.
For vertical text path direction, no action occurs if CAP is already at the top margin. If CAP is
above the top margin (via one of the Move CAP commands), BS functions as if the top margin
were row 0, the logical page top boundary.
In proportional spacing, a single <BS> centers the overstriking character with the character
being over-struck. After printing the overstrike character, CAP is at the same position as
before the <BS>. Multiple backspaces each move back the distance of the last printable character or space.
!
10.9.2
HP DeskJet 600/800/900 & HP 2000 Series printers backspace using only the last proportional character width. The resulting cursor relocation is therefore not a fixed constant.
Carriage Return
<CR>
Moves CAP to the left margin on the current row.
10.9.3
Space
<SP>
Moves CAP forward one character position (defined by HMI) on the current line.
CAP does not move if it is already at the right margin and end-of-line wrap is not enabled. If
end-of-line wrap is enabled, CAP moves to the left margin of the next row and then prints the
space.
10.9.4
Linefeed
<LF>
HP DeskJet 600, 700, 800, 900 & HP 2000 Series PCL Developer’s Guide
49
HP PCL Commands
Moves CAP to the same horizontal position, one row down. If perforation skip mode is
enabled, a linefeed that would go beyond the text length boundary moves CAP to the same
horizontal position at the top of form on the next page. If perforation skip mode is disabled, text
is printed to the end of the page and onto the next page. Text in the unprintable region may be
lost.
10.9.5
Formfeed
<FF>
Formfeed advances CAP to the same horizontal position at the top of the form on the next
page. Top of Form is at the vertical position computed by top of form = top margin + (3/4 x line
spacing)
!
10.9.6
Multiple formfeeds in sequence are not interpreted as a single formfeed.
Horizontal Tab
<HT>
Horizontal Tab moves CAP to the next tab stop on the current line.
The first tab stop is at the left margin; additional tab stops are fixed at every 8 columns to the
right margin. Tabs represent a logical position and, thus, refer to different physical positions for
different settings of HMI.
The following are some boundary cases:
4 If the requested tab stop is outside the right margin and CAP is at or to the left of the right
margin, HT moves CAP to the right margin.
4 If the requested tab stop is outside the printable area and CAP is to the right of the right
margin, HT moves CAP to the edge of the printable area.
4 If CAP is to the left of the left margin, HT moves CAP to the left margin.
Tabs do not cause lines to be wrapped if end-of-line-wrap mode is enabled.
HMI determines current column width. If HMI is changed, the physical location of each tab
stop moves. HT has no effect if the HMI is 0.

Designates inter-character spacing as either proportional or fixed.
If proportional spacing is specified and no proportional font is available in the requested symbol set, a fixed spacing font with the current pitch specification is chosen, if available.
If fixed spacing is requested but no fixed-pitch font is available, a proportional font is chosen, if
available.
For fixed-space bitmap fonts, both pitch and height are used for selection of font character
size. For fixed-space scalable fonts, only pitch is used. For proportional bitmap and scalable
fonts, only height is used.

If the exact pitch is unavailable, the next larger pitch is selected. If a larger pitch is unavailable,
the closest smaller pitch is selected.
Pitch is ignored when selecting proportional fonts, but saved in the font select table and available when a fixed space font is selected.
For fixed space bitmap fonts, both pitch and height are used for font selection. For fixed space
scalable fonts, only pitch is used. For proportional scalable fonts, only height is used. For dualfixed space fonts, only the pitch is used.
For scalable fonts, pitch is converted to a corresponding point size (height), which is scaled by
the printer. Effective pitch ranges are thus limited by height constraints.

EFFECT
Height for current font is set
Specifies font height in points (1/72 inch).
If the requested height is unavailable, the closest heights are chosen for the next selection criteria. The closest value is in terms of absolute difference: e.g., if 6, 8, and 12 point fonts are
available and 10 is requested, both 8 and 12 point fonts are considered.
Fractional values may be specified when requesting height. All bitmap fonts within 0.25 points
of the requested height are considered. If a 12 point font is requested, fonts between 11.75
and 12.25 are considered. Or, to put it another way, if 6, 8, and 11.75 point fonts are available
and 10 is requested, both the 8 and 11.75 fonts are considered.
Height is ignored when selecting a fixed space scalable font; but the value is saved in the font
select table and available when a proportional font is selected.
If no font within .25 points is available, HP DeskJet selects the next smaller height. If no
smaller height is available, the next larger height is selected.

MATCHING ALGORITHM
The following procedure matches requested styles with available styles:
4 Printers recognizing only style values 0, l, and 2 discard requests for larger values.
4 Printers recognizing style values from 0 to 255 convert requests for larger values to 255.
The request is discarded if an exact match is not found after conversion.
4 An exact match is required for style selection. If the requested value is within the range of
the printer and a match is not made, the request is ignored, but saved in the font select
table, available for the next selection.
Whenever a requested font parameter is ignored, the parameter is retained in the font select
table for future font selections; and the current font selection process continues as if the
parameter had never been requested.
In some HP PCL machines, the style word may be an operator: slanting, condensing, expanding, outlining, and shadowing operations are all theoretically possible. For example, if italic is
unavailable, slant may be added to the upright face. No new command sequence is required
to support such operations.
EXAMPLE: Assume that a font style of “italic compressed contour” is desired. The value(#)
would be computed as follows:
1 + (2 x 4) + (3 x 32) = 105

EFFECT
Designates the thickness of the strokes that compose the characters of a font.
If the designated stroke weight is unavailable and 0 or greater, the closest thicker weight is
selected. If a thicker weight is unavailable, the closest thinner weight is selected.
If the designated stroke weight is unavailable and less than 0, the closest thinner weight is
selected. If a thinner weight is unavailable, the closest thicker weight is selected.
Many typefaces were designed for advertising, and a “medium” was used to describe the standard treatment. Later, additional treatments were designed for text use. Therefore, the typeface treatment designation “medium” may not always take a HP PCL value of 0. This value
may be assigned to “book” or “text” instead.

EFFECT
Font with indicated ID is
selected
Designates a font by ID as primary or secondary. The designated font, if present, is selected
as the primary/secondary font, and all the attributes in the primary/ secondary font select table
are changed to match those of the designated font. Pitch, however, is not changed if the designated font is proportional. No action occurs if the designated font is unavailable. See the
Font Symbol Set Command for Symbol Set ID Numbers.
!
Pitch and height are unchanged if the designated font is scalable.
If a proportional-space scalable font is selected by ID, the Height command should be
sent prior to the Font Selection ID command to specify point size. Otherwise, the size will
be determined by the height of the former font (as listed in the font select table).
For shared or multi-user environments, HP recommends that soft fonts be selected by
attribute rather than ID.

Downloading Fonts
Currently, the HP DeskJet 600 Series and 850/855 Series printers are the only printers that
accept downloaded fonts. Note that the HP DeskJet format soft fonts are designed for use
with the HP DeskJet 500 Series printers. The following sections discuss the format for the HP
LaserJet format soft fonts, which is the type used for the DeskJet 600 Series and 850/855
Series printers.
Before sending font data, the font must first be assigned an identification number so the font
can be referenced by subsequent HP PCL commands.

EFFECT
Downloads a font definition and
assigns the font the current font
ID
This command must be sent prior to downloading the characters in the font.
Note that this command downloads the entire font definition, which includes the font descriptor, as well as any additional data segments such as the Global Intellifont Segment, the Global
TrueType Segment, the Copyright, the Application Support Segment, etc. The value (#) of this
command gives the size of the definition; the first word of the definition gives the size of the
descriptor. The descriptor, which is the first part of the definition, defines characteristics common to all the characters of a font.
Some devices, such as PaintJet, may not use a font definition or may ignore some fields; but
each field should contain a valid value for printer compatibility. Missing data and “reserved”
fields should be set to 0; excess data should be discarded.
The two font definitions recognized by the HP DeskJet 600, 850, 870, 890, & HP 2000 Series
printers are provided in the section of this guide entitled “Fonts”.
4 Bitmap - Older definition for bitmap fonts. Not recommended for new devices.
4 Resolution - Specified Bitmap - Replaces the previous Bitmap definition. Allows font resolution to be specified in dots-per-inch.

Raster Graphics
The following HP PCL commands apply to the printing of raster graphic images on HP DeskJet 600/800/900 & HP 2000 Series printers.
10.13.1
Raster Mode
The Start Raster (Esc * r # A) command begins a restricted state called raster mode. Raster
mode locks out commands that would affect rendering of the graphics image. These commands remain locked out until End Raster (Esc * r C).
10.13.2
Commands Locked Out of Raster Mode
The following raster commands are ignored in raster mode. They should be used to define a
graphic image’s parameters before entering graphics mode.

Defines the resolution at which graphics data is to be printed
To assure that the graphic is printed without data loss, an unsupported resolution is mapped to
the next higher supported resolution. For example, a request for 125 dpi on a HP DeskJet 600/
810/830/895/900 or HP 2000 Series printer would result in 150 dpi being selected as the

a multiple of 8 to the next higher multiple of eight (i.e., the next byte boundary).
Specifies the width in pixels of the raster area.
Raster width extends from the left graphics margin to one of the following:
4 The distance specified by the Source Raster Width (Esc * t # H) command.
4 The right edge of the logical page, if the specified width would extend outside the printable
area.
4 The right edge of the printable area, if width is not specified.
HP DeskJet printers always clip at the right edge of the printable area.
The left graphics margin is set to one of the following:
4 CAP (explicit Start Raster).
4 Left edge of the logical page (explicit or implicit Start Raster).
The printer clips data that would extend outside the specified width. If width is not specified,
the printer clips at the right edge of the printable area. If a width greater than the printable area
is specified, the printer clips at the right edge of the logical page.
The printer zero-fills rows not specified for the full width. These zero-filled portions of a row
map to either white or transparent, depending on the media type currently selected (Esc * v #
N).
!
On color devices, a zero-fill is not necessarily white. For example RGB data set to zero
prints as black on a HP DeskJet printer. Undefined graphics space would therefore print
as black.

Raster Data Transfer
The Raster Transfer commands (Esc * b # V, Esc * b # W) define how many bytes will be
interpreted as binary raster data
The Transfer Raster by Plane (Esc * b # V) command is used when the data is encoded by
plane, as specified by the Simple Color (Esc * r # U) command. Transfer Raster by Plane is
used to send each plane in the row except the last; Transfer Raster by Row (Esc * b # W)
must be used to send the last plane and advance the row.
The Transfer Raster by Row (Esc * b # W) command moves CAP to the beginning of the
next pixel row after the graphics data in the command is sent to the printer. The command is
used for single-color devices, for the last plane in a multi-plane row, or for color raster transfer
when the data is encoded by pixel.

EFFECT
Specified number of bytes of
graphics data for a single plane
of data is set to the printer. The
row pointer is not incremented.
Sends a plane of data to the printer and advances to the next plane, but not to the next row.
The number of planes per row is specified by the Simple Color (Esc * r # U) command (also
known as Set Planes per Row). The first plane sent represents the least significant bit in the
pixel.
Since Transfer Raster by Plane (Esc * b # V) does not advance the row, it cannot be used
for the last plane or for single-plane rows. Only Transfer Raster by Row (Esc * b # W) can
advance the row.
The amount of data sent varies from plane to plane and is independent of raster width. Planes
whose data specifies a row shorter than the raster width are zero-filled. Empty planes can be
sent by Esc * b 0 V.

K data
Transfers the number of bytes specified in the value field to the printer in a row by row or block
format, depending on the current compression method (Esc * b # M), then moves CAP to the
next row.
This command is used in single-color and multi-color printers where data is encoded by row
rather than by pixel. Because this command advances the row, it is also used for single-plane
rows or the last plane in a multi-plane row.
CAP is updated for each row in both row or block formats. For row formats, CAP is reset to the
left graphics margin. For block formats, CAP is reset to the X coordinate of the block; and the
Y coordinate is incremented.
The amount of data sent by this command can vary from row to row. If the picture width allows
more data than is sent, the undefined area is zero-filled. Undefined planes in a multi-plane row
are zero-filled. Black and white devices interpret zeros as white; color devices interpret zero
according to the current palette.
The plane pointer in a multi-plane row is reset to 1 after the data is transferred.
The data field is interpreted according to the current compression method (Esc * b # M).

Raster Compression
Since raster images take a large amount of memory and processing time, raster data should
be reduced as much as possible. White-space data transfer can be reduced by sending empty
rows and planes (Esc * b 0 W, Esc * b 0 V), or by offsetting the left graphic margin (Esc * r 1
A) or the vertical starting point (Esc * b # Y). The Compression Method (Esc * b # M) command provides several other ways of compressing data.

EFFECT
Determines how raster data is interpreted in the Transfer Raster by Row or Transfer Raster by
Plane commands. The compression method stays in effect until explicitly changed to another
method or reset by Reset (Esc E) or End raster (Esc * r C).
Method 0- Unencoded
This is a simple binary transfer: no compression.
Method 1- Run-Length Encoding
Method 1 interprets raster data as byte pairs. The first byte tells how many times the second
byte is repeated, i.e., a repetition count. The second byte is the data to be printed. The repetition count can be 0 through 255. A count of 0 means the byte pattern occurs once and is not
repeated; a count of 1 means the pattern occurs twice; and a count of 255 means the pattern
occurs 256 times.

HP PCL Commands
!
Method 1 requires byte pairs: a Transfer Raster (Esc * b # V or Esc * b # W) command
with an odd value field is ignored and the data discarded.
Method 2 - Tagged Image File Format Encoding (TIFF revision 4)
Method 2 (“packbit” encoding) combines methods 0 and 1, with blocks of repeated bytes and
blocks of literal (unencoded) bytes. A control byte precedes the raster data; it indicates the
number of succeeding bytes, and whether they are repeated or literal.
The control byte is in 2’s complement format. If bit 7 is set (byte = -1 to -127), the following
bytes are repeated. The control byte’s absolute value is the number of repetitions (occurrences = repetitions + 1). For example, a control byte of -5 means the subsequent byte is
repeated 5 times (6 occurrences).
If bit 7 of the control byte is zero (byte = 0 to 127), the following bytes are literal. The number
of succeeding data bytes is 1 + the value of the control byte. A control byte of 0 means 1 literal
byte follows; a control byte of 6 means 7 literal bytes follow.
A control byte of -128 is ignored; the next byte is then treated as a control byte.
It is more efficient to code two consecutive identical bytes as a repeated byte, unless these
bytes are preceded and followed by literal bytes. Three-byte repeats should always be
encoded as replicate runs.
The row length indicated by the Transfer Raster commands (Esc * b # V, Esc * b # W)
has precedence if it is met before the literal run count.

Method 3 - Delta Row Encoding
This method replaces only bytes in the current row that are different from the preceding row
(seed row). Unreplaced bytes are replicated from the seed row. The current row then becomes
the seed row.
A delta compression string consists of a command byte and the replacement (delta) bytes:
[(Command byte)(1 to 8 replacement bytes)]
The command byte has two parts: the number of consecutive replacement bytes that follow,
and the left offset from the current byte position.
7
5
Replacement count (1 - 8)
4
0
Left offset from the current byte (O - 30)
Three bits of the command byte contain the replacement count: the number of consecutive
replacement bytes that follow (000 = 1, 111 = 8).
Five bits contain the offset from the current byte to the next replacement byte. The current byte
follows the last replacement byte or, at the beginning of a row, the left graphics margin. An offset of 0 is the current byte; an offset of I is the byte following the current byte.
For example, assume the current byte is the first byte in the row. An offset of 7 skips bytes 0
through 6, and a replacement count of 5 replaces bytes 7 through 11. The new current byte is
12. A second offset of 3 skips bytes 12, 13, and 14; byte 15 is the next byte to be replaced.
HP DeskJet 600, 700, 800, 900 & HP 2000 Series PCL Developer’s Guide
79
HP PCL Commands
The values of the offset have the following definitions:
0 to 30:
The offset is 0 to 30.
31:
The offset is 31 or greater. If the offset is 31, an additional offset byte follows
the command byte. The offset in the command byte is added to the offset byte.
If the off- set byte is 0, the offset is 31; if the offset byte is 255, additional offset
bytes follow. The last offset byte will have a value less than 255. All the offset
bytes are added to the offset in the command byte to get the offset value. For
example, if there are 2 offset bytes, and the last byte contains 175, the total offset would be:
31 + 255 + 175 = 461.
If more than eight delta bytes are needed, additional command byte/delta bytes are added:
[(Command Byte)(1-8 Delta Bytes)][(Command Byte)(1-8 Delta Bytes)] . . .
The seed row is zeroed when raster mode is entered. Every raster transfer affects the seed
row, regardless of the compression method. For example, an Esc * b 0 W while in compression method 0 zeros the seed row. This allows method 3 to be combined with other methods in
order to achieve better compression performance.
A vertical offset also affects the seed row: the Y Offset (Esc * b # Y) command skips rows,
leaving them blank, and zeros the seed row.
Method 3 operates on each plane independently, and a separate seed row is maintained for
each graphic plane. However, a Y Offset affects all planes and seed rows simultaneously.
The examples below show how method 3 affects Raster Transfer and Y Offset commands:
Esc b 0 W
Repeat the previous row. The seed row is unchanged
Esc b 1 Y
Move down one raster row. Zero the seed row.
Esc b 0 Y
Move down zero raster rows. Zero the seed row
Seed row width is set to the source raster width at the beginning of raster mode. Source Raster Width (Esc * r # S) updates seed row width.
If the Transfer Raster (Esc * b # V or Esc * b # W) command byte count is less than the control
byte count, only the transfer byte count number of bytes are replaced. If the transfer count is
greater than the control count, only the control byte number of bytes are replaced; for example, if the control byte count is 10 but the transfer count is 3, only 3 bytes are replaced.
If the last byte indicated by the transfer command value is a control byte, it is ignored. Therefore, Esc * b 1 W does not affect the seed row, but causes the previous row to be repeated.

3m selects method 3, and 2W indicates that 2 bytes of data will follow. The upper three bits of
the command byte are zero, indicating that one byte will be replaced. The lower five bits contain a relative offset of 1, indicating that the replacement occurs one byte in from the current
position. The replacement byte follows and contains 11111111.
Row 2 - Esc * b 2 W (00000010)(11110000)
The first three bits of the command bye are 0 indicating one byte will be replaced. The lower
five bits contain a relative offset of 2; so the replacement will occur 2 bytes from the current
position. The replacement byte 11110000 follows.
Row 3 - Esc * b 5 W (00000000)(00001111)(00100010)(10101010)(1010 1010)
Three bytes are replaced using two commands. The first three bits of the first command byte
are zero, indicating a single byte replacement, and the next five bits are zero, indicating a relative offset of zero. The replacement byte 00001111 follows.
The first three bits of the second command byte are 001, indicating the replacement of two
bytes; and the lower five bits contain a relative offset of two. The two replacement bytes
(10101010)(10101010) follow the command byte.
Method 9 - Compressed Replacement Delta Row Encoding
Like Method 3, this method replaces only bytes in the current row that differ from the preceding (seed) row. Unlike Method 3, the replacement (delta) bytes may be encoded.
A delta compression string consists of a command byte, optional offset bytes, optional
replacement count bytes, and the replacement data.

HP PCL Commands
Control Bit:
Determines whether the replacement data is encoded, and also the bit
boundaries of the command byte’s other two fields.
Offset Count:
The number of bytes the replacement data is offset from the current position in the seed row.
Replacement
Count:
The number of consecutive data bytes to be replaced.
Control Bit = 0
If the control bit is 0, the replacement data is uncompressed. Bits 0-2 contain the replacement
count; bits 3-6 contain the offset count. The replacement count is the number of bytes to be
replaced by the bytes following the command byte. The offset count is the location these
replacement bytes will occupy relative to the current position in the seed row.
Like compression method 3, the current byte follows the last replacement byte or, at the beginning of a row, the left graphics margin. An offset of 0 is the current byte; an offset of 1 is the
byte following the current byte.

count byte is 255, another offset count byte follows. The last offset count byte will be less than
255.
One more byte than that indicated by the replacement count will be replaced. That is, 000 = 1
and 111 = 8. For example, if the replacement count is 5, then 6 bytes are replaced.
If the replacement count is 7, a replacement count byte follows the command byte and any offset count bytes. If the replacement count byte is 0, then 8 bytes are replaced. If the replacement count byte is 255, another replacement count byte follows. The last replacement count
byte will be less than 255. All of the replacement count bytes are added to the replacement
count in the command byte to get the total replacement byte count. One more than the total
replacement byte count will be replaced.
Control Bit = 1
Operation is similar if the control bit is 1, except that the replacement data is run length
encoded and the bit boundaries are different. Bits 5 and 6 contain the offset count; bits 0 - 4
contain the replacement count. As when the control bit is 0, optional offset bytes and replacement bytes may be added.

Default = 0
Range = 0 to number of currently active planes.
For example, if the printer is in 3-plane mode and Esc * b 0 S was sent, then:
4 The Cyan plane would use the Cyan plane from the previous row
as a seed plane.
4 The Magenta plane would use the Magenta plane from the previous
row as a seed plane.
4 The Yellow plane would use the Yellow plane from the previous
row as a seed plane.
If the printer is in 3-plane CMY mode and Esc * b 1 S is sent, then:
4 The Cyan plane would use the Yellow plane from the previous row as
a seed plane.
4 The Magenta plane would use the Cyan plane from the current row
as a seed plane.
4 The Yellow plane would use the Magenta plane from the current row
as a seed plane.

EFFECT
The Simple Color (Esc * r # U) command, sometimes referred to as Set Planes Per Row,
allows color selection from a fixed palette. CMY or RGB raster data must be transferred by
plane (Esc * b # V) as well as by row (Esc * b # W). The pixel encoding mode is indexed planar.Creates a fixed-size palette whose color specification cannot be modified.
!
The HP DeskJet 600 printer, which is a single-pen device, maps a value parameter of -4
to 3-plane CMY, converting K data to composite black.
The absolute value of the value field indicates the number of planes per row of raster data to
be sent. The number of entries in the new palette is 2n, with index values 0 to 2n -1. For example a 4-plane palette has 16 entries, with index numbers 0 to 15.
A value field of 1 creates a 2-entry black and white default HP LaserJet palette.
A value field of 3 creates an 8-entry Device RGB palette (compatible with a HP PCL Imaging
Mode palette.
A value field of -3 creates an 8-entry palette in Device CMY color space.
A value field of -4 supports 4-plane Device KCMY color. Plane 1 is the black pen, and planes
2, 3, and 4 respectively are the CMY planes.
The four Simple Color palettes are shown below.

The ordering for color data planes when the RGB palette is selected is RGB. The first
Transfer By Plane command will send Red Data to the printer, the second will send Green
Data, and the Blue Data is sent with a Transfer By Row command, which increments the

Sets the foreground color to the specified index of the current palette.
Out-of-range values are mapped into a new index via modulo (palette size). For example, if
the current palette size is 8, and the selected index for the foreground color command is 10,
the index is mapped into the index of 2 (i.e., 10 modulo 8).
Foreground color affects the following HP PCL page marking primitives in HP DeskJet 600/
800/900 & HP 2000 Series printers.
4 Text characters
4 Solid or monochrome patterned rectangular area fills (rules) (800, 855, 870, 890 only)
4 Raster images (see note below)
!
The HP DeskJet 600 printer will ignore this command if the black pen is installed (foreground color will be black). When the color pen is installed, the printer will map a request
for a four plane palette to a 3 plane palette, using composite black in place of black.
Foreground color interacts with color raster images on HP DeskJet 1200 Series and HP
DeskJet 1600 Series printers. Foreground color does not affect raster color on HP DeskJet 600/800/900 & HP 2000 Series printers. If you are developing printer driver code that
will be ported to drivers for HP DeskJet 1200 and/or 1600 Series printer, to avoid undesired interactions, select a black foreground color when transmitting raster images to the
printer.

A soft font is composed of a Font Definition (font header) and a series of character definitions.
Both are described below. In order to use the standard bitmap font definition on a HP DeskJet
600 or 85X Series printers, the Font Descriptor Size field must be set to exactly 64. The First
Code and Last Code fields must also contain valid information. HP LaserJet printers do not
enforce these restrictions, and it is therefore common for developers leveraging code and
fonts from previous HP LaserJet development to experience problems.

Spacing (BOOL)
Specifies the type of font spacing. Fixed spacing is 0; proportional spacing is l; dual-fixed

!
11.2.11
HP DeskJet printers prior to the HP DeskJet 600 Series treat values other than 0 or 1 as 1,
and require that landscape fonts have fixed spacing.
Symbol Set (UINT)
Bound Font - Specifies the symbol set characteristic of the font.
The value for this field is derived from the symbol set identification number (ID) used by Esc(lD
in the font selection process. The number portion (#) and the ASCII value of the letter portion
(L) of the ID are used to obtain the symbol set descriptor field value:
Symbol Set Descriptor Field = (# x 32) + (L - 64)
Assume the symbol set is US ASCII ISO-6. The symbol set table in the section
“Font Selection by Attribute,” identifies US ASCII as “0U”. Since # = 0 and U = 85, the field
value is 21:
Symbol Set Descriptor Field = (0 x 32) + (85 - 64) = 21
Unbound Font - This field should be set to 56 (1X) for unbound fonts.
11.2.12
Character Set (UINT16)
The Character Set field specifies the native mapping of a large font.
11.2.13
Pitch (UINT)
Bitmap Font - Specifies the pitch of the font in quarter-dot units (i.e., four quarter-dot units
equal one dot; also known as radix dots). It combines with Pitch Extended to specify the pitch
of the font in 1/1024 dots. Pitch defines the default HMI for the font.
For example, at 300 dpi (1200 quarter-dots/inch), a 17-ppi font has a pitch field of 70 and a
non-zero pitch extended field.
(1 inch /17char) x (300 dots / inch) x (4 radix dots / dot) = 70.588 radix dots
The remainder 0.588 is converted back to dots and then to 1/1024 dots:
(0.588 radix dots /4 radix dots per dot) x (1024 units / dot) = 150 units/dot
Pitch Extended is set to 1501/1024 units.
For proportional fonts, the width “printed” for a control code space is determined by the pitch
value unless HMI has been changed.

11.2.14
Height (UINT)
Bitmap Font - Specifies the font’s height in quarter-dot units. The value, converted to points
(1/72 inch), is used as the height characteristic of the font. Height combines with Height
Extended to specify the design height of the font in 1/1024 dots.
For example, a 10 point font at 300 dpi has a height field of 166 quarter dots (1200 quarter
dots/inch, 1/72 inch/ point).
(10 point) x (1 inch /72 point) x (300 dots/inch) x (4 quarter-dots/dot) = 166.667

Vendor Number (bits 11-14) - This HP-assigned value is between 0 and 15.
Vendor Version (bits 10, 9) - This value is between 0 and 3. It will change when the vendor
changes the width of a font or adds new characters to a font. A vendor code of 0 is reserved
for generic typeface selection so that older one-byte typeface values can still be used in the
generic typeface selection process.
Typeface Base Value (bits 0 to 8) - This value is between 0 and 511. Some of these values
include appearance width and structure information (i.e., Helvetica Compressed and Helvetica

A typeface family value in which both Vendor and Version numbers are 0 is reserved for
generic type- face selection. That is, for typeface family values less than 512, the printer
exactly matches the LSB typeface base value field. For typeface values greater than or

Cap Height (UINT)
Cap height is a percentage of the Em of a font and is used to calculate the distance from the
cap line (top of an unaccented, upper-case letter, e.g., “H”) to the baseline. An Em is a measure in decipoints of the height of a font; e.g., the em of a 10-point font is 100 decipoints.
Bitmap Font - Fonts containing a 0 in this field are assumed to have a cap height percentage
of 70.87% of em. The Cap Height data is represented as the product of the cap height percentage and the maximum unsigned integer:
0.7087 x 65535 = 46445
For nonzero values the Cap Height percentage is calculated as follows:
% = (Cap Height Data /65535) x 100
Scalable Font - Contains the cap height in design window units (as defined in the Scale Factor field).

Continuation (BOOL)
Specifies whether the following data is a character descriptor block (0) or a continuation (nonzero) of the data associated with the previous character descriptor.
If the byte count in the value field of the Define Character command exceeds 32767, the character must be sent in 2 or more blocks. The additional bytes are sent in as many continuation
blocks as needed (except compound characters).
Compound characters (e.g., accented characters) cannot be continued.
A character that has not received all the character data is an “incomplete” character. There is
at most one incomplete character at a time. If an incomplete character is deleted, any subsequent continuation downloads are ignored.
A continuation block that is downloaded before the first block was received is ignored.
12.0.3
Descriptor Size (UBYTE)
Specifies character descriptor size in bytes. The descriptor follows the character header,
which consists of the first two bytes of the character definition (the Format and Continuation
fields). For bitmap characters, the descriptor size includes Descriptor Size through Delta X.
For Intellifont characters, the descriptor size includes only Descriptor Size and Class. For TrueType characters, the descriptor size includes Descriptor Size and Class, but additional
descriptor information can follow; therefore, the minimum TrueType descriptor size is 2.

Class 1: Bitmap Data - Class 1 character data is a string of bytes containing the dot-per-bit
image of the character, with no compression. A “1” bit causes the dot to be printed.
The data is grouped in dot rows describing a one-dot high strip of the character from left to
right in the direction of the printer’s raster scan. The dot rows are organized from top to bottom
108
HP DeskJet 600, 700, 800, 900 & HP 2000 Series PCL Developer’s Guide
HP LaserJet Bitmap Character Definition
of the character (in portrait orientation): the first dot row of data corresponds to the first dot row
of the character. The end of each row is padded with zero bits so it contains an integral number of bytes.
The number of bytes of the character data should be exactly the Character Width (in bytes)
times the Character Height. Additional data is discarded. The character will consist only of the
downloaded character data, even if this is insufficient.
Class 2: Compressed Bitmap Character Data - (see the figure below) Class 2 character
data is composed of a string of bytes using a compressed run-length-with-line-repetition format. The first byte tells how many times the first row is repeated after the initial row. The second byte tells how many white dots start the row (if the first dot is black, the second byte is 0).
The third byte tells how many black dots follow, the fourth byte tells how many white dots follow that, etc., until the end of the row.
The character width (dots) field in the character descriptor determines the row width: the dot
count for each row in the character cell must equal the character width. For example, in the following figure, the cell width is 20; thus each row (excluding the repetition count byte) adds up
to 20.
The fully described row is duplicated the number of times indicated by its first byte. After the
duplication, the next byte indicates the repetition count for the next row.
More than 255 dots of the same type in a row is indicated by a byte containing 255, followed
by a byte containing 0 (meaning there are none of the opposite type of dots), followed by a
byte containing the count of the remaining dots of the current type.

Banner Printing
13.0
Banner Printing
The following information concerns the printing of continuous forms (banners, z-fold media) on
the HP DeskJet 680 and 690 Series printers. This is the only information made available by
the VCD R&D lab. There are no new HP PCL commands for banner printing. The only HP
PCL command that has actually been modified in association with printing on continuous
media is the command. Only media sizes (as selected with the Media Size command) US Letter and ISO/JIS A4 can be used for continuous form printing.
13.0.1
Media Source
Esc & l # H
The HP DeskJet 680 and 690 Series printers add support for sources -1 (z-fold) and 1 (Tray 1,
cut sheet).
Default media source is Tray 1.
Note that the value used for the variable parameter in the command (“#”), like the rest of the
command, is an ASCII character string. Therefore, a value of “-1” would actually be sent to
the printer as a hex equivalent of “2E 31”.
!
The HP DeskJet 680 and 690 Series printers support values -1, 0, and 1. When the media
source is z-fold, a value of ”0” will eject one blank page. If media remains in the mechanism, the printer will enter a paper-unloading state (see Unloading Continuous Media,
below). In this state, the top LED on the face of the printer will flash, and pressing the
RESUME button will advance one page.
The banner source is only supported for media sizes (see Esc & l # A) of US-Letter (11 inches)
and ISO/JIS A4 (11 2/3 inches). All other media sizes will only load from the cut sheet media
source (Tray 1). This is to ensure that only banners of lengths HP has tested will be printed.
If the printer runs out of paper in the middle of a banner, the rest of the banner data (until the
Esc & l 0 L) will be discarded. There will be no front panel indication when this data is discarded.
In the absence of bidirectional communication, if Tray 1 is selected while continuous media is
loaded at the paper sensor, the mechanism will print the cut sheet job on the continuous
media, as if it were a cut sheet job.

113
Banner Printing
13.0.2
Margins
Margins in banners are handled the same as margins with cutsheet media. Default top and
bottom margins are 1/2 inch. If perforation skip is disabled (Esc * l 0 L), the margins are
adjusted to 0 top and bottom. The initial cursor (CAP) position in each page is calculated by:
top margin + (3/4 * current line feed) {where current line feed = 1/lines per inch}
With perf skip disabled, the default cursor position is:
0 + (3/4 * 1/6 inch) = 1/8 inch
To position raster graphics at position 0, it is necessary to execute a negative cursor move.
For example Esc * p - 38 Y will move backwards 1/8 inch. Esc * p 0 Y also works when perf
skip is disabled
13.0.3
Command Sequence
The media source must be selected for Continuous Forms before the negative cursor move is
performed, as the Media Source command will default the cursor position to the top left corner
of the defined logical page. In most cases, this defaulting action will leave some amount of top
margin, resulting in a gap appearing in the banner image at the media perforation. By setting
the media source first, and following that command with the negative cursor move, banner
images can be printed. Remember that the negative cursor move must be performed at the
beginning of each new page.
13.0.4
Moving to a New Logical Page
Since raster graphics moves are clipped to the current logical page, it is necessary to explicitly
move to a new page once the current page is filled. As shown in the HP PCL example on the
following page, this may be accomplished by sending a form feed (followed by the appropriate
cursor positioning).
Raster graphics advances never move to the next page, any excess rasters (raster data that
would exceed the logical page boundary) will be discarded. If a raster block spans a page
boundary, it must be sent as multiple blocks, along with the appropriate cursor positioning to
align on the physical media.
For text printing on continuous media, line feeds or form feeds may be used to advance to the
next logical page.
13.0.5
Unloading Continuous Media
When the printer has completed a continuous-media print job, it will advance the paper to the
end of the page after the current page. If media remains in the mechanism, the top LED will
flash. Pressing the Resume button will advance one page. Media must be removed and reinserted between each banner print job.

13.0.6
Power-On with Continuous Media
The firmware will remember what media type is loaded. If powered down with continuous
media loaded, the firmware will power on with the top LED flashing (as described above)
allowing the user to unload the continuous media if cutsheet media is desired for the next print
job.

If the Power key is pressed while in the middle of a banner page, the media will first be
advanced to the next top of form before turning the printer off. Any unprinted data will be lost.
13.0.8
Printing Cutsheet with Z-Fold Media
Attempting to print cutsheet media while z-fold media is loaded and there exists a bidirectional
I/O connection between the host and printer, will halt the printer in an error state. Power
cycling will clear the error.
Without a bidirectional I/O connection, the printer will format and print the cutsheet job on the
z-fold media.

This example is a guideline to illustrate page formatting. Depending upon the application,
other methods may be used to achieve the desired printed page. For example, if you want a
header and/or footer to be placed on each page, you can turn Perforation Skip Mode OFF,
allowing the header to sit at the top margin. You can then use vertical positioning commands
to move CAP into position for the main text. Likewise, you can set the printer side margins to
0. You can then use horizontal positioning commands to position CAP for the start of each
line.
