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 upperand 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.

iii

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.

iv

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%, white, 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" units) 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.

v

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, it is 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.

vi

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.

vii

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
	unless the type of ROM fitted to the printer is Flash ROM, in which case it can be
	written to electronically via the parallel port of the printer .
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 use 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.

viii

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
Stick font	monospacing and proportional spacing.
	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 languages use this method.
Vertical plot size	The original vertical size of an imported HP-GL and HP-GL/2 image.
	ix

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.

1. 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 laser printer. 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 PCL models. For the differences between each model, see the Appendix "Model Comparison."

“PCL6” includes both “PCLXL” and “PCL5e”.

As for “PCL5e”, it is described in “chapter 2 PCL” of this manual.

As for “PCLXL”, it is mainly used with Windows driver, and its command is structured by binary code. Therefore, it is not described in this manual.

For basic set-up information, such as how to connect the printer to your computer, look in the User’s guide. The User’s guide also describes the printers control panel and how you can set various options using the keys.

2. AREAS OF USE

There are several different applications for which you may want to use your HL-Series laser printer. Four general areas are outlined in the following sections.

2.1Using 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.

2.2Graphics

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.

2.3Programming

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 */

}

2.4Font Development

In LaserJet mode you can send your own character designs to an HL-Series laser printer 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.

2.INTRODUCTION

This laser printer provides a complete emulation of the supported Hewlett Packard LaserJet printer. Features include raster and vector graphics, support for bitmap and scalable fonts and page control. There are many resident fonts in the printer and you can gain access to more by inserting a font cartridge/card or the storage device into the printer or by downloading fonts from your computer.

3.CONTROLLING THE PRINTER

3.1.Control Codes

Control codes are ASCII codes that tell the printer to perform a given function, such as a carriage return. You can send these codes to the printer as part of a program.

3.1.1. Backspace

(08)

<08h>

ASCII code 8. This code moves the cursor one column to the left.

3.1.2. Line feed

(10)

<0Ah>

ASCII code 10. This code performs a line feed.

3.1.3. Form feed

(12)

<0Ch>

ASCII code 12. This code ejects the most recently printed page from the printer.

3.1.4. Carriage return

(13)

<0Dh>

ASCII code 13. This code performs a carriage return.

3.1.5. Select primary font

(14)

<0Eh>

ASCII code 15. When you send this code to the printer subsequent characters will be printed in the current primary font. This is explained further in the sub-section entitled “Using fonts”.

3.1.6. Select secondary font (15)

<0Fh>

ASCII code 14. When you send this code to the printer subsequent characters will be printed in the current secondary font. This is explained further in the sub-section entitled “Using fonts”.

3.1.7. Escape

(27)

<1Bh>

ASCII code 27. You must use this character code to start every instruction sequence that you send to the printer.

3.1.8. Horizontal tab

(09) <09h>

ASCII code 9. This code moves the cursor one tab position to the right. The tab positions are at the left margin and at the left edge of every 8th column as defined by the horizontal motion index (HMI) described in the next section, entitled “The Page”.

3.1.9. Space

(32)

<20h>

ASCII code 32. This code moves the cursor one column to the right.

3.2.Escape Sequences

Escape sequences, also known as PCL (Printer Control Language) commands, tell the printer which operations to perform. An escape sequence consists of the Esc character followed by a string of characters which define the operation to be performed. Some escape sequences require parameter values. These are included in the sequence as numeric characters. The final letter of an escape sequence must be uppercase: all others must be lowercase.

You can send the printer instructions by embedding escape sequences in programs or in word processed documents.

In this manual escape sequences are shown as they would be entered, except that the character # in a sequence indicates that a number should be included at that point in the sequence. If no number is included, the printer interprets that parameter’s value as 0.

When downloading fonts or sending raster scan images to the printer the final uppercase character of the sequence is followed by the relevant data.

Two escape sequences can be combined into one if the first three characters of each sequence (including the Esc character itself) are the same. Hence, Esc*c45G and Esc*c2P may be combined to give Esc*c45g2P. The uppercase ‘G’ which terminated the first sequence becomes a lowercase character in the combined sequence. Combined escape sequences are executed left to right, so be careful to place commands in the order in which you want them to be executed.

Esc*c45G		Esc*c2P

Esc*c45g2P

3.2.1.Line termination

You can set the carriage return, line feed and form feed control codes to perform compound functions. You can either do this using the printer’s control panel (see the User Guide) or by sending the printer the following escape sequence:

Esc&k#G (27)(38)(107)#(71) <1Bh><26h><6Bh>#<47h>

•0 = Carriage return, line feed and form feed perform their normal functions.

•1 = Carriage return performs carriage return/line feed, line feed and form feed perform their normal functions.

•2 = Carriage return performs its normal function, line feed performs carriage return/line feed and form feed performs carriage return/form feed.

•3 = Carriage return performs carriage return/line feed, line feed performs carriage return/line feed and form feed performs carriage return/form feed.

0	CR→CR	LF→LF	FF→FF
1	CR→CR+LF	LF→LF	FF→FF
2	CR→CR	LF→CR+LF	FF→CR+FF
3	CR→CR+LF	LF→CR+LF	FF→CR+FF
