Glossary
Absolute plotting A method of plotting in the HP-GL and HP-GL/2 graphics language where
coordinates are specified relative to the origin of the coordinate system
currently in use.
Anchor point The top left-hand corner of the PCL picture frame. You can position this on
the page using a PCL command.
Anisotropic scaling A form of image scaling using the SC command in HP-GL and HP-GL/2
mode in which the user units can be of different sizes. Hence the entire
graphics window can be used to display the image.
ASCII The standard system for assigning number codes (0 ~ 255) to alphabetic,
numeric and control code characters.
Attribute A characteristic of a downloadable font or a character of a Downloadable font
that is represented by a number of a fixed length.
Bitmap font A font whose characters are defined as raster images. The characters that
make up a bitmap font are of a fixed size.
Bold A wider line thickness for typographical characters, used to make the text
stand out, for example, in headings.
Calling a macro A way of running a macro in which changes to the modified print environment
are not retained when the macro has finished running.
Cartridge A storage medium that you can insert into the printer cartridge slots.
Cartridges can store fonts. The advantage of using cartridges is that they
allow you to use more fonts without taking up printer memory space.
Cartridge font A font that is stored on a cartridge. These are widely available commercially.
Character cell The imaginary grid on which downloadable characters are designed.
Character code A number assigned to a character that uniquely identifies it.
Character descriptor A block of data that describes the characteristics of an individual character in
a downloadable font, such as its width and height.
Character set A selection of different characters. Characters sets normally include the
alphabet in both upper- and lowercase, the digits' 0-9, punctuation marks,
common mathematical symbols and a few other useful characters. There are
also some specialized character sets that are used for specific applications like
mathematics. A font is defined as having a particular character set.
Column A vertical sub-division of the page whose width is equal to the HMI
(horizontal motion index). The print position moves across the page one
column width when any single character is printed ( in a monospaced font),
or when a space character is printed ( in a proportionally spaced font). See
also HMI.

Control code An ASCII code that tells the computer to perform a particular function, such
as a carriage return.
Control panel reset A reset or factory reset performed using the printer control panel.
Cross-hatching A method of shading using perpendicular diagonal lines that cross one
another.
Current units The current unit type in use in HP-GL and HP-GL/2 mode. Current units are
either user units or graphics units depending on whether an SC command has
been used.
Cursor Although the printer does not have a cursor, it is sometimes easier to visualize
the printer's operation in terms of a cursor that can be moved from place to
place on the page.
Cursor position The current position of the imaginary cursor.
Decipoint A unit of measure equal to 1/720".
Default conditions A set of HP-GL and HP-GL/2 mode settings that you restore using the DF;
command. The default conditions are a subset of the initial settings.
Destination image The graphic image that is already in place on a page and to which the source
image is applied in the LaserJet series print model.
Dots A unit of measure equal to 1/600", the smallest increment that the cursor can
move.
Downloadable font A character font that can be downloaded from your computer to the printer.
You can either buy Downloadable fonts or create your own. A downloadable
font consists of a font descriptor block followed by a character code,
character descriptor block and the data for each character in the font.
Downloading The process of sending either a font, a macro or a graphic image from your
computer to the printer.
Effective window The area of the page on which HP-GL and HP-GL/2 output can appear. The
effective window is determined by the overlap of the logical page, the PCL
picture frame, the hard clip and the soft clip limits.
Emulation mode A mode of operation in which the printer imitates the functions of a different
model.
Enabling a macro for overlay A macro that is enabled for overlay runs as the final operation before each
page is printed, using the macro overlay environment printer settings.
Escape sequence The Esc character followed by a string of other characters that tell the printer
which operation to perform.
Factory default environment The collection of printer settings that have been made to the printer before it
leaves the factory. You can reset the printer to the factory settings either by
using a printer command or using the control panel.
Factory reset A reset in which LaserJet mode is made the current emulation mode and the
factory default environment is restored.

Fill A shading applied to a shape that you have drawn.
Fixed spacing See monospacing.
Font A collection of characters that are designed to work in harmony together. A
font has several characteristics that identify it uniquely: character or symbol
set, spacing, pitch, height or point size, style, stroke weight and typeface.
Fonts can either be resident in the printer's ROM, installed on cartridge or
downloaded from your computer. You can either buy downloadable fonts
commercially or create your own. The word "font" is often wrongly used to
mean "typeface". A font is confined to a single height or point size whereas a
typeface is not.
Font descriptor A block of data that is downloaded to the printer as the first part of a
downloaded font. The font descriptor describes the characteristics that are
common to every character in the font, such as stroke weight, and contains
other relevant information.
Graphics mode initial settings The HP-GL and HP-GL/2 mode settings that are in effect when you enter HP-
GL and HP-GL/2 mode. You can restore the initial conditions using the IN;
command.
Graphics units The default units of the HP-GL and HP-GL/2 coordinate system. Also
sometimes called plotter units.
Graphics window The area on the page in which HP-GL and HP-GL/2 graphic images can
appear. Initially this is the same as the picture frame, but you can change the
size, position and aspect ratio of the graphics window using the IW
command.
Gray scale A degree of continuous shading ranging from 0%, very light gray, to 100%,
black.
Hard clip limits The area of the page on which it is physically possible to print using HP-GL
and HP-GL/2 graphics language commands. The hard clip limits are
determined by the size of the physical page and are equivalent to the LaserJet
mode printable area.
Hatching A method of shading using parallel lines.
Height The height in typographic points (1/72") of an unaccented capital letter in a
font.
HMI Horizontal motion index. The horizontal distance that the print position
moves across the page when any single character is printed ( in a monospaced
font ), or when a space character is printed ( in a proportionally spaced font
). You can set the HMI using printer commands, however, when you alter
any font characteristic ( in effect, select a new font ) or switch between the
primary and secondary fonts, the HMI is reset to its default value based on
the newly selected font.
Horizontal plot size The original horizontal size of an imported HP-GL and HP-GL/2 image.

Internal font A font that is stored in the printer ROM and is therefore always available for
use, for example, Brougham 10 pitch, or a font generated from a scalable
typeface stored in the printer's ROM, for example, Tennessee bold 15 pt.
Isotropic scaling A form of image scaling using the SC command in HP-GL or HP-GL/2 mode
in which the user units must be of equal size. Hence it may not be possible to
use the entire graphics window to display the image.
Justification The way in which text is aligned. For example, left justification involves
aligning the left end of every line of text.
Label A text string that forms part of an HP-GL and HP-GL/2 plot.
Landscape The orientation in which the top edge of the page is longer than the side edges.
Logical page The area of the physical page on which the cursor can be positioned in
LaserJet mode. You can use PCL commands to specify the position of the
logical page on the physical page. Also known as the PCL addressable area.
LSB i) The least significant byte of a set of data bytes.
ii) The least significant bit of a single byte of data.
Macro A sequence of PCL commands that can be stored in the printer memory. To
run the sequence you need only use a single PCL command.
Macro execution Executing a macro is a way of running a macro whereby any changes made to
the modified print environment by the macro are retained when macro
execution has been completed.
Macro overlay environment Used only by a macro that has been enabled for overlay. A combination of
the user default environment and the modified print environment.
Medium The line thickness of normal type.
Modified print environment The collection of all current LaserJet printer settings. This environment is
saved if you call a macro or enter HP-GL and HP-GL/2 mode, and then
restored when the macro has finished running or when you quit HP-GL or
HP-GL/2 mode.
Monospacing Some bitmap fonts are printed with each character occupying the same space
on a line of text. This is known as monospacing.
MSB i) The most significant byte of a set of data bytes.
ii) The most significant bit of a single byte of data.
Pattern i) The hatching or cross-hatching that can be applied to an outline shape.
ii) The non-white areas of the source image in the LaserJet print model.
Pattern transparency The patterned ( non-white ) areas of the source image are either transparent,
in which case the destination image is visible through the white parts of the
pattern, or opaque, in which case the destination image is not visible at all
throughout the patterned areas of the source image.
PCL Printer Control Language. The language consisting of escape sequences that
is used to control the printer in LaserJet mode
PCL addressable area See logical page.

PCL picture frame See picture frame.
Pen Although this printer is a laser printer the HP-GL/2 and HP-GL graphics
languages retains the notion of a pen and allows you to select between two
pens, white and black. You must select a pen before you can draw anything.
The HP-GL and HP-GL/2 language were originally developed for use with
plotters and the terminology remains.
Perforation skip A feature whereby the printer automatically compensates for a page break
and resumes printing from the top of the text area on the next page.
Permanent font A downloaded font that is retained when a printer reset is performed.
Permanent macro A macro stored in the printer that will not be erased if the printer is reset.
Physical page The paper or envelope on which the printer prints.
Picture frame The area of the physical page in which HP-GL and HP-GL/2 graphic images
can be printed.
Pitch The number of characters in one inch of text. Only applicable to monospaced
(fixed pitch fonts.)
Plot A drawing produced using the HP-GL and HP-GL/2 graphics language. So
called because the language was originally invented for use with plotters.
Plotter units See graphics units.
Point The standard unit of measurement for character height. Equal to 1/72".
Point factor scaling A form of image scaling using the SC command in HP-GL or HP-GL/2 mode
in which the user units and the location of the scaling point P1 are specified in
terms of graphics units.
Point size See height.
Polygon A shape consisting of one or more closed groups of connected lines.
Polygon buffer An area of printer memory in which you can store one or more polygons and
sub-polygons defined using HP-GL and HP-GL/2 commands. Some HP-GL
and HP-GL/2 commands use the polygon buffer automatically.
Portrait The orientation in which the side edges of the page are longer than the top
edge.
Posture A component of a font's style - whether it is upright or italic.
Primary font In LaserJet mode the printer maintains two current font settings. The primary
font is the first of these.
Print model A way of describing the interaction between different graphic elements (
source image, pattern and destination image ).
Printable area The area of the page on which the printer can print.

Print position The position from which printing of the next character or graphic object will
begin, providing that no operations that change the print position are
performed in the interim.
Proportional spacing Fonts intended for high quality typographic output use a method of character
spacing in which the space occupied by a single character on a line of text
depends on the individual design of the character. This is known as
proportional spacing. Scalable fonts are almost invariably proportionally
spaced.
RAM Random Access Memory. The printer's memory in which fonts and macros
can be stored and where pages that are to be printed are composed.
Raster graphics A method of representing a graphic image as a series of zeroes and ones that
correspond to white and black dots respectively.
Relative plotting A method of plotting in the HP-GL and HP-GL/2 graphics language where
coordinates are specified relative to the point at which the last graphics
command terminated.
Reset When you reset the printer you restore a base set of conditions. A reset can
either be performed using the control panel or by sending the printer a reset
command. There are two types of reset, the normal reset and factory reset. A
normal reset simply restores the current emulation mode with the most recent
control panel settings -- it does not change the emulation mode itself. A
factory reset makes LaserJet mode the current emulation mode and restores
the factory default environment.
Resident font See internal font.
ROM Read Only Memory. Part of the printer's memory that contains the software
controlling the printer and the printer internal fonts. The ROM cannot be
altered.
Row A horizontal sub-division of the page whose height is equal to the VMI
(vertical motion index). The print position moves down the page a distance
equal to the row height when a line feed is performed.
Sans serif A kind of typeface normally used for headlines. Sans serif typefaces do not
have little hooks (serifs) on the individual characters. This helps Sans serif
headline text stand out more prominently.
Scalable fonts A font for which you can specify the character size. The printer will
automatically scale the characters to the size you require.
Scaling In HP-GL or HP-GL/2 mode you can use the SC command to scale graphic
images. The three types of scaling are known as anisotropic, isotropic and
point factor scaling.
Scaling points Two imaginary points called P1 and P2 that define a rectangular area relative
to the picture frame. You can user the HP-GL or HP-GL/2 SC and IP or IR
commands to transform and scale images by changing the relationship
between the two scaling points.
Scalable typeface A typeface for which you can choose a point size (height) in order to obtain a
particular font for printing. For example, you might select the Utah typeface

and then select 14 pt. as the height. The printer has many resident typefaces.
You can also buy scalable typeface cartridge and disks.
Secondary font In LaserJet mode the printer maintains two current font settings. The
secondary font is the second of these.
Serif A kind of typeface normally used for body text. Serif typefaces have little
hooks (serifs) on the individual characters that makes text more readable.
Soft clip limits See graphics window. The soft limits are determined by the IW command.
Source image The graphic image that is applied to the destination image in the LaserJet
print model. The interaction of the two images is determined by the current
source and pattern transparency settings.
Source transparency The source image is either transparent, in which case the destination image is
visible throughout the white parts of the source image, or opaque, in which
case the destination image is not visible at all through the source image.
Spacing The way in which a font's characters are arranged on a line of text. See
monospacing and proportional spacing.
Stick font The default HP-GL and HP-GL/2 font consisting of thin lined characters.
Stroke weight The thickness of the lines that comprise the characters in a particular font.
Medium, bold and light stroke weights are commonly used.
Sub-polygon A shape consisting of a closed group of points connected by lines. Several
sub-polygons can form one polygon.
Symbol set See character set.
Tab channel A set of up to sixteen vertical tab stops. Up to eight vertical tab channels can
be set up in the Epson FX-850 mode.
Temporary font A downloaded font that is erased from the printer's memory when a printer
reset is performed. To use the font again you must download it again.
Temporary macro A macro that is erased from the printer's memory when a reset is performed.
If you want to use the macro again you must redefine it and download it to the
printer again.
Text area The area of the physical page on which the printer can place text.
Text direction The orientation of printed text relative to the physical page.
TIFF Tagged Image File Format. A common file format used for storing raster
graphics data.
Transparency See pattern transparency and source transparency.
Typeface The design style of a set of typographic characters. The character design is
intended to make the characters work together cohesively to produce readable
text. The word "font" is often erroneously used to mean "typeface".
User default environment The current combination of LaserJet factory default settings and settings
made using the control panel. This is the environment that is in effect when

you switch on the printer in LaserJet mode or change to LaserJet emulation
from another emulation mode. You can reset the printer to its user default
settings either by using a printer command or using the control panel.
User units Coordinate units specified by the user with the HP-GL and HP-GL/2 SC
command.
Vector graphics A method of defining graphic images in terms of coordinates, points and
lines. The HP-GL and HP-GL/2 graphics language uses this method.
Vertical plot size The original vertical size of an imported HP-GL and HP-GL/2 image.
VMI Vertical motion index. The vertical distance that the print position moves
down the page when a line feed is performed. This can be set using printer
commands or with the printer's control panel by adjusting the "Lines" menu
option in PAGE FORMAT MODE.

About the manual
This technical reference manual is intended to help you get the most out of each of the emulation
modes supported by your HL Series laserprinter. It is divided into nine sections - this introductory
section and one section for each of the emulation modes. Each emulation mode section describes the
software commands (the escape sequences and control codes) that you can use to make the printer
perform each of its available functions. Some example programs are included to give you useful
ideas.
This manual is for our PCL5 models. For the differences between each model, see the Appendix
"Model Comparison."
For basic set-up information, such as how to connect the printer to your computer, look in the User
guide. The User guide also describes the printers control panel and how you can set various options
using the keys.
Areas of use
There are several different applications for which you may want to use your HL Series laserprinter.
Four general areas are outlined in the following sections.
USING WORD-PROCESSING PACKAGES AND SPREADSHEETS
You may simply wish to use the printer with your software application packages, such
as word-processors or spreadsheets. Many software packages automatically send
commands to the printer requesting particular type styles, character sizes and
specifying page set-up information and other relevant data. In this case you will not
need to use this manual, as your software package will perform the task of controlling
the printer for you. Other packages allow you to embed software commands within
your word-processed or spreadsheet documents. This manual describes the commands
you need, and you can simply include them in the form that your package requires. In
either case, read the documentation that came with your software to find out its own
specific requirements for driving a printer.

GRAPHICS
HP-GL/2 or HP-GL mode offers many powerful graphic features that enable you to draw and print
detailed images quickly and easily. Many commercial graphic packages, notably computer-aided
design applications programs, produce HP-GL/2 or HP-GL output. LaserJet mode also has several
graphics features. You can either write your own programs to generate images or use existing
graphics software.
PROGRAMMING
If you are writing software, for example in BASIC or C, to drive the printer, the description and
formal specification of each command will enable you to transcribe them straight into your
programs. Below is a simple example of a program to draw and print a three inch black square. The
program is given in both C and BASIC.
C language program
#include <stdio.h>
main()
{
FILE *prn; /* initialization section */
prn = fopen("PRN","wb");
fprintf(prn,"\33E"); /* Esc E - Reset the printer */
fprintf(prn,"\33%0B"); /* Esc%0B - Enter HP-GL/2 */
fprintf(prn,"IN"); /* Initialize */
fprintf(prn,"SP1PA1024,1024"); /* Select pen 1 & move to 0,0
*/
fprintf(prn,"PDFT1RA4096,4096"); /* Draw 3" solid square */
fprintf(prn,"\33%0A"); /* Quit HP-GL/2 & restore original
cursor position */
fprintf(prn,"\33E /* Reset and eject page */
}
BASIC language program
10 LPRINT CHR$(27);"E"; :REM Esc E - Reset the printer
20 LPRINT CHR$(27);"%0B"; :REM Esc%0B - Enter HP-GL/2
30 LPRINT "IN"; :REM Initialize
40 LPRINT "SP1PA1024,1024"; :REM Select pen 1 & move to 0,0
50 LPRINT "PDFT1RA4096,4096"; :REM Draw 3" solid square
60 LPRINT CHR$(27);"%0A"; :REM Quit HP-GL/2 & restore
original cursor position
70 LPRINT CHR$(27);"E"; :REM Reset and eject page
FONT DEVELOPMENT
In LaserJet 4 mode you can send your own character designs to the HL Series laserprinter and print
text using them. To do this you need first to design your characters on paper. Having done this you
can then either input and download your characters using a commercial software package, or encode
your designs numerically and write your own program to download them.
