Printer Features
Introduction Hewlett-Packard printers which support the PCL 5 printer
language contain slightly different feature sets, each suitable for that printer’s intended use. Each printer implements minor variations of PCL 5 as a result of those differences. With new printer releases, new features may be added with new commands and/or PCL operations which require documentation.
The purpose of this guide is to identify the differences in the implementation of the PCL 5 Printer Language for different HP LaserJet and DeskJet printers, as compared to that described in the PCL 5 Printer Language Technical Reference Manual. This guide describes new commands and exceptions to existing commands unique to the printers, as well as internal typeface/font support and print environment settings.
Feature Set 1-1
This guide covers the following HP LaserJet printers:
Introduction Date
LaserJet III March 1990 LaserJet IIID September 1990 LaserJet IIISi February 1991 LaserJet IIIP May 1991 LaserJet 4, 4M October 1992 LaserJet 4Si, 4SiMx April 1993 LaserJet 4L, 4ML May 1993 LaserJet 4P, 4MP September 1993 LaserJet 4 Plus, 4M Plus May 1994 LaserJet 4PJ May 1994 LaserJet 4V, 4MV September 1994 DeskJet 1200C May 1993 DeskJet 1200/PS May 1993 Color LaserJet September 1994 LaserJet 4LC March 1995 DeskJet 1600C March 1995 LaserJet 4LJ Pro May 1995 LaserJet 5P, 5MP May 1995 LaserJet 5L September 1995 LaserJet 5Si, 5SiMx N ovember 1995 Color LaserJet 5, 5M March 1996 LaserJet 5, 5M April 1996 LaserJet 5Si Mopier October 1996 LaserJet 6P, 6MP October 1996 LaserJet 6L September 1997 LaserJet 4000 series November 1997
1-2 Feature Set
This guide also covers the HP 1200C and 1600C DeskJet printers.
PCL Feature Support
Table 1-1, the PCL Feature Support Matrix, lists all the printer commands from the PCL 5 Printer Language Technical Reference Manual and identifies which of these commands are supported by the various printers. More detailed PCL information for each PCL 5 printer is provided in Chapter 2.
Note The PCL 5 Printer Language Technical Reference Manual
(part number 5961-0509) was revised for the release of the HP LaserJet 4 printer and contains all PCL language features up to the HP LaserJet 4 printer.
With the introduction of the HP LaserJet 4 printer, Hewlett-Packard enhanced the PCL 5 printer language to provide some new features. The major improvements to the PCL 5 printer language are listed below.
600 dpi support for higher quality printing 45 scalable typefaces for greater type variety TrueType rasterizer (in addition to the Intellifont
rasterizer) for fast Windows printing, and for matching Windows and printer type (easy WYSIWYG)
New graphics commands for faster and better curves and shading quality
Bi-directional I/O for easier use and sharing by providing printer status to computer applications
Automatic and faster printer language switching Automatic I/O switching for faster I/O rates Improved memory management so most pages print in
standard memory Improved PCL and HP-GL/2 performance for faster
graphics and text printing
Feature Set 1-3
Notes In T able 1-1, if the command value field parameters are
not listed, then all parameters are supported by printers that support that command.
The value in parentheses following a command parameter identifies the parameter value field value (for example, the parameter “Letter (2)” indicates that the value field to select letter size in the Page Size command is “2” ).
Commands which are not supported (“ns”) by a printer are ignored.
1-4 Feature Set
PCL 5 Technical Reference Manual Corrections
This section describes updates to the PCL 5 Printer Language Technical Reference Manual (5961-0509).
Because this manual will not be updated, any changes to it are documented in this guide. Some errors have been identified in the PCL 5 Printer Language Technical Reference Manual since its printing. Those errors are identified and corrections are provided on this page.

In Figure 4-6 on page 4-18, the two escape sequences at the top should read “(?&u100D) and (?&u200D)” instead of “(?&u100B) and (?&u200B).”
Transparent Print Data Command
The last sentence in the note at the bottom of page 8-33 should read “Refer to the PCL 5 Comparison Guide, Appendix A, for character codes for the various symbol sets.” instead of “Refer to Appendix A for character codes for the various symbol sets.”
User-Defined Pattern Command
In Figure 13-10 on page 13-19, byte zero should read Format (20) instead of Format (0)
On page 13-21, Format (Byte 0) should read “0” for a 300 DPI user-defined pattern header and “20” for a resolution-specified user-defined pattern header.

Printer-Specific Differences
Introduction Each Hewlett-Packard printer implements minor variations
of PCL 5 in order to best suit its intended use. This chapter describes specific differences that are important when developing applications for the various PCL 5 printers. The sections in this chapter describe such information as new commands not contained in the PCL 5 Printer Language Technical Reference Manual, and other miscellaneous differences in PCL operation particular to that printer.
HP LaserJet III and IIID Printers
With the introduction of the HP LaserJet III printer, Hewlett-Packard introduced the PCL 5 printer language. The PCL 5 printer language incorporated many new features over the PCL 4 language. A few of the more significant features included such things as the addition of a scalable font technology, HP-GL/2 vector graphics language support, print model features, raster graphics enhancements, and the Print Direction command.
The HP LaserJet IIID printer language support is basically identical to the HP LaserJet III printer except for the addition of the duplex feature, dual input bin, envelope feeder support and their associated commands (see Table 1-1).
Printer-Specific Differences 2-1
HP LaserJet IIISi
Printer
Several new PCL features were added to the PCL 5 language with the release of the HP LaserJet IIISi printer. These new features are summarized in Table 2-1 below.

New Additions Four variations of Univers Condensed; ITC Zapf
Dingbats in five symbol sets.
HP LaserJet IIIP Printer
2-2 Printer-Specific Differences
Several new PCL features were added to the PCL 5 language with the release of the HP LaserJet IIIP printer. These new features are summarized in Table 2-2. One new feature listed here is adaptive compression (method 5) for the Raster Compression Mode command. In addition to compressing data for transmission, if certain rules are followed (discussed below), the HP LaserJet IIIP printer will store adaptive compressed data in compressed format and only decompress it when required for printing. There are certain requirements which must be met for this data to be stored in compressed format. These requirements are discussed following Table 2-2.

Modified In addition to selecting internal patterns, this command
is now used to assign an ID to a user-defined pattern as
well as to select patterns. Also, paramet e r range is
extended from 100 to 32,767.
New Feature Enables user to build a symbol set which contains user-
selected characters. New Identifies the characters for a user-defined symbol set. New Assigns a number for identification to the user-defined
symbol set. New Used to make user-defined symbol sets permanent or
temporary, or to delete them.
New Feature Allows typefaces (unbound fonts), not just fonts (bound
fonts) to be downloaded to the printer. New Addition of a new header used for unbound fonts (font
type 10).
Printer-Specific Differences 2-3
Raster Graphics
Adaptive
Compression (IIIP)
Adaptive compression was added to the PCL language with the introduction of the HP LaserJet IIIP printer. Adaptive compression (or method 5 as it is referred to) is a method for compressing raster data using the raster Set Compression Method command (parameter value 5). (Refer to the Set Compression Method command in the PCL 5 Printer Language Technical Reference manual for detailed information on using this compression technique.) Also, refer to Chapter 4 in this document, “Raster Graphics Adaptive Compression (Method 5)” for additional information.
HP LaserJet 4 Printer
Several new PCL features were added to the PCL 5 language with the release of the HP LaserJet 4 printer. These new features are summarized in Table 2-3. Most of these features are described in the revised PCL 5 Printer Language Technical Reference Manual (part number 5961-0509). (This revised technical reference manual is supplied as part of the Technical Reference Documentation Package which can be obtained by ordering part number 5961-0601.) In addition, there are some additional differences for the HP LaserJet 4 printer that are not covered in the technical reference manual but are described below.
Note The HP LaserJet 4M printer, in addition to PCL, contains
PostScript and a LocalTalk I/O for printing in the Macintosh environment. PCL operation and the PCL internal fonts for this printer are identical to the HP LaserJet 4 printer. Thus, for PCL information for the HP LaserJet 4M printer, refer to the HP LaserJet 4 printer features.

EtherT alk MIO) us ing AppleTalk protocol.
Modified Supports 1-32,767 copies as does the HP LaserJet IIISi
printer.
New Allows selection of the units of measure for cursor moves,
drawing rules, and for character spacing (font metrics).
Modified A parameter value is added for B5 envelope size; the HP
LaserJet 4 printer supports the four standard paper sizes and five envelope sizes.
New Header Printer will expand 300 dpi bitmap fonts to 600 dpi. A ne w
300/600 dpi bitmap font descriptor has been added to allow bitmap fonts to be created that work at either 1/300 or 1/600 inch printer resolution.
New Header A new Universal header has been added to allow design of
typefaces of different scaling technologies to be supported by one header. This header is used to support TrueType on the HP LaserJet 4 printer. (This header will be used to support any other new scaling technologies HP may add in the future).
New TrueType scaling technology support has been added to
the printer.
New Several new Intellifont and TrueType internal typefaces
(and supporting symbol sets) are now provided in the printer.
Modified Parameter values have been added to support raster
resolutions of 200 dpi and 600 dpi.
New Header A new 300/600 dpi user-defined pattern header has been
added to support patterns that work at either 1/300 or 1/600 inch printer resolution.

polygons using the odd/even fill technique. A second
technique, non-zero winding fill, has been added.
Modified HP-GL/2 is now supported in macros.
New Added to allow the user to communicate with the MIO
card in the printer.
2-6 Printer-Specific Differences
Configuration
Command
(AppleTalk)
The Configuration command allows a user to send PCL jobs to the printer over AppleTalk. This data is sent in the form of “key/value” data pairs (refer to “AppleTalk Configuration” below for more information).
?&b#W [key]<sp>[value] # = Number of data bytes that follow command
Default = 0 Range = 0 - 32767
[key] can be 1 character through 32765 characters. [value] can be 1 character through 32765 characters.
AppleTalk Configuration
The HP LaserJet 4 printer can be configured to receive PCL print jobs over an AppleTalk connection using the Configuration command. The HP LaserJet 4 MIO AppleTalk interfaces support three key values: RENAME, JOB, and TYPE. These keys are used for configuring an installed LocalTalk or EtherTalk MIO card to allow PCL print jobs generated by a Macintosh host to be printed.
Printer-Specific Differences 2-7
Notes PostScript in the HP LaserJet 4 printer supports the
PostScript level 1 operators setprintername, AppleTalktype, and jobname, and the PostScript level 2 setdevparams operator to allow PostScript print jobs to change the Name Binding Protocol (NBP) printer name and printer type, as well as change the print job name.
MIO sub-system in the printer accepts a new NBP printer name, NBP printer type, and job name from either the PCL or PostScript personalities. The printer passes that information across the MIO interface to the installed MIO card which indicated support for the MIO AppleTalk extensions. The MIO sub-system will treat the PCL NBP type and the PostScript NBP type separately.
For information about AppleTalk Name Binding Protocol refer to Inside AppleTalk published by Addison Wesley Company, Inc.
RENAME
RENAME changes the printer name portion of the printer’s AppleTalk Name Binding Protocol name field.
?&b#WRENAME<sp>printername
Valid characters for the printer name include 0-255 except for characters $00, “@” ($40), “:” ($3A), “*” ($2A), “=” ($3D), and $C5. The printername must contain at least one character, and only the first 31 characters are used. If an invalid character ($00 is not treated as an invalid character) is contained in the printername, the printer will ignore the escape sequence. If the printer encounters the NULL ($00) character, the printer uses the NULL character to terminate the printer name. All the characters preceding the NULL will be used. If another device on the AppleTalk network uses the same printer name, another character is added to the end of the printer name.
The default printername is the printer model (for example, “HP LaserJet 4”).
2-8 Printer-Specific Differences
JOB
JOB renames the current job name.
?&b#WJOB<sp>jobname
All characters are valid. For the job name the first 127 characters are used.
There is no default jobname.
TYPE
TYPE changes the type (device type) portion of the printer’s AppleTalk Name Binding Protocol type field.
?&b#WTYPE<sp>devicetype
Valid characters for the device type include 0-255 except for characters $00, “@” ($40), “:” ($3A), “*” ($2A), “=” ($3D), and $C5. The devicetype must contain at least one character, and only the first 31 characters are used. If an invalid character ($00 is not treated as an invalid character) is contained in the devicetype, the printer will ignore the escape sequence. If the printer encounters the NULL ($00) character in the devicetype, it uses the NULL character to terminate the device type. All the characters preceding the NULL will be used as the devicetype. If the device type is invalid then the printer’s type is not changed.
The default device type for PCL is “HP LaserJet 4” and for PostScript is “LaserWriter”.
Printer-Specific Differences 2-9
HP LaserJet 4Si
Printer
The HP LaserJet 4Si printer is the follow-on to the HP LaserJet IIISi printer. The HP LaserJet 4Si printer contains many new PCL features over the HP LaserJet IIISi. PCL support for the HP LaserJet 4Si printer is identical to the HP LaserJet 4 printer except for the addition of the duplex feature, dual output bin (see Table 1-1) and resource saving.
Like the HP LaserJet IIISi printer, the HP LaserJet 4Si supports the HP LaserJet IIISi features listed in Table 2-1 with two exceptions. First, is that the HP LaserJet 4Si does not support ITC Zapf Dingbats. Font support for the HP LaserJet 4Si is identical to the HP LaserJet 4 printer (refer to Chapter 3, “Internal Typefaces/Fonts and Symbol Sets,” for complete font support information). The other exception concerns job separation. The PCL Job Separation command is not supported. The HP LaserJet 4Si printer handles job separation through the control panel. If a PCL Job Separation command is received by the printer it will be ignored. Refer to the HP LaserJet 4Si User’s Manual (part number C2010-90901) for additional information.
Resource saving, a new feature in the HP LaserJet 4Si printer, allows saving information for the current language (PCL or PostScript) when switching to the other language. If resource saving is enabled (from the control panel or PJL; no PCL commands are required for this operation), all the permanent fonts, macros, and user-defined patterns plus some other miscellaneous data is saved in a reserved portion of printer memory. This data is stored until the language is enabled again. When the language is re-enabled, the stored data will be made available for use.
2-10 Printer-Specific Differences
HP LaserJet 4L Printer
The HP LaserJet 4L printer is a smaller, low-cost HP LaserJet printer. The control panel on this printer is limited to one button with four indicators. Many of the control panel functions must be controlled program­matically using Hewlett-Packard’s Printer Job Language (refer to the Printer Job Language Technical Reference Manual, part number 5021-0380 for detailed PJL information).
The HP LaserJet 4L printer PCL command features are identical to those of the HP LaserJet 4 printer PCL features, except for some differences in parameter values (such as for paper source—refer to Table 1-1). Additional features which do not require PCL command control include EconoMode and HP Memory Enhancement technology (MEt). EconoMode causes the printer to print less dots, thus saving toner. Memory Enhancement technology involves some memory saving techniques to better utilize available memory (refer to Chapter 5, “Memory Usage” for additional information).
Typefaces in the HP LaserJet 4L printer are different from those of the HP LaserJet 4 printer. The HP LaserJet 4 printer contains both Intellifont and T r ueType scaling technologies, but the 4L contains only Intellifont scaling technology. Thus, the 4L does not contain any of the TrueType typefaces, with one modification. The TrueType Wingdings typeface has been converted to Intellifont format and is available in the printer as an Intellifont typeface (refer to Chapter 3, “Internal Typefaces/Fonts and Symbol Sets” for additional information).
Printer-Specific Differences 2-11
HP LaserJet 4ML Printer
The HP LaserJet 4ML printer is similar to the HP LaserJet 4L printer, however, the 4ML includes PostScript and a LocalTalk I/O for printing in the Macintosh environment. The HP LaserJet 4ML printer also includes some new PCL features: print model logical operation (ROP3) and pixel placement, as described on the following pages.
The HP LaserJet 4ML supports the typefaces that the HP LaserJet 4 printer supports. Several of the typefaces in the HP LaserJet 4ML printer have additional support for the Latin 2 and Latin 5 symbol sets (refer to Chapter 3, “Internal Typefaces/Fonts and Symbol Sets,” for complete font support information).

New Modifies the print model to allow logical operations (such as
AND, OR, XOR, NOT) to be performed on source, texture, and destination.
New Allows user to select either grid intersection or grid
centered placement of pixels when rendering an image in PCL.
New Allows user to select either grid intersection or grid
centered placement of pixels when rendering an image in HP-GL/2.
New Allows the user to use logical operations (ROP’s) in
HP-GL/2.
2-12 Printer-Specific Differences
Logical Operations With the introduction of the HP LaserJet 4ML printer the
print model was expanded to include logical operations. The basic print model defines how a pattern, source image,
and destination image are applied to each other using the print model’s transparent and opaque modes to produce a resulting image (refer to the PCL 5 Printer Language Technical Reference Manual for detailed information about the basic print model operation). The Logical Operations (?*l#O) command can apply logical functions (e.g., AND, OR, XOR, NOT) to any of these operands except transparency, which must be specified first.
The print model process consists of the following steps:
1. Specify source and/or pattern transparency modes, if desired.
2. Specify the logical operation (or use the default).
3. Define the desired operands (source, destination, pattern).
Definitions
Source: The source image may be one of the following:
HP-GL/2 primitives Rules Characters Raster images (single plane mask or multiplane color)
Destination: The destination image contains whatever is currently defined on the page. It includes any images placed through previous operations.
Pattern or Texture: The pattern is defined by Current Pattern (?*v#T). The terms pattern and texture are used interchangeably in this section.
Printer-Specific Differences 2-13
Transparency Modes: The white pixels of the source and/or pattern may be made transparent (source transparency 0, pattern transparency 0). The destination shows through these areas.
Transparency modes are set by the Source Transparency (?*v#N) and Pattern Transparency ( ?*v#O) commands (refer to the PCL 5 Printer Language Technical Reference Manual).
The print model allows logical operations, such as AND, OR, XOR, NOT, to be performed on source, texture, and destination images. Transparency modes and Logical Operation must be specified before printable data is sent.
Operators
Source Transparency (specified before logical operation; default is transparent)
Pattern T r ansparency (specified before logical operation; default is transparent)
Logical Operators (default is Texture OR Source)
Operands
Source objects: character cell, raster image, rule, HP-GL/2 vectors and polygons
Texture: pattern mask Destination: current page definition
Assuming three bits per pixel, the following diagram shows the print model process.
2-14 Printer-Specific Differences
Notes The Logical Operation command (?*l#O) provides 255
possible logical operations. All of these logic operations map directly to their ROP3 (raster operation) counterparts (see the Microsoft Document, Reference, Volume 2, Chapter 11, Binary and Ternary Raster Operation Codes).
The logical operations were defined by Microsoft Windows for an RGB color space (a ‘‘1’’ is white and a “0” is black).
Logical Operations
and Transparency
Interactions
As described above, transparency modes operate in addition to logical operations. The logical operations in Table 2-5, Logical Operations (ROP3), on the following pages, are true only if source and pattern transparency (for white pixels) are explicitly set to opaque (?*v1N and ?*v1O). If source and/or pattern transparency modes are transparent (defaulted), the additional operations shown on the following page must be performed to achieve the final result.
Printer-Specific Differences 2-15
The four basic interactions are:
Case 1: Source and Pattern are opaque. Return ROP3 ( Dest, Src, Texture ).
Case 2: Source is opaque, Pattern is transparent. Temporary_ROP3 = ROP3 ( Dest, Src, Texture ).
Image_A = Temporary_ROP3, & Not Src. Image_B = Temporary_ROP3 & Pattern. Image_C = Not Pattern & Src & Dest. Return Image_A | Image_B | Image_C
Case 3: Source is transparent, Pattern is opaque. Temporary_ROP3 = ROP3 ( Dest, Src, Texture ).
Image_A = Temporary_ROP3 & Src. Image_B = Dest & Not Src. Return Image_A | Image_B
Case 4: Source and Pattern are transparent Temporary_ROP3 = ROP3 ( Dest, Src, Texture ).
Image_A = Temporary_ROP3 & Src & Pattern. Image_B = Dest & Not Src. Image_C = Dest & Not Pattern. Return Image_A | Image_B | Image_C.

opaque (not defaulted), values specified by this command map directly to the ROP3 (raster operation) table values on the following page. However, when source and/or pattern transparency modes are set transparent, the additional operations shown on the previous page must be performed to achieve the final result.
Logical operations in the table are shown in RPN (reverse polish notation). For example, the value 225 corresponds to TDSoxn, the logical function of
NOT (texture XOR (source OR destination))
command. This command sets the ROP value which affects not only
PCL operation but also the HP-GL/2 ROP value.
Printer-Specific Differences 2-17
Example: The Logical Operation default value is 252 (TSo),
corresponding to a logical function of:
The result is computed below for both case 1 (source and pattern opaque) and case 4 (source and pattern transparent) on the previous page. Note that the ROP3 value of 252 results only with case 1, when both source and pattern transparency modes are set to opaque.

Table 2-6, Logical Operations (ROP3), shows the mapping between input values and their logical operations. Note that the logical operations are specified as RPN (reverse polish notation) equations. Here is a key to describe what the Boolean Function values mean;
S = Source a = AND T = Texture o = OR D = Destination n = NOT
x = EXCLUSIVE OR
Note Since logical operations are interpreted in RGB space
(white = 1 and black = 0) rather than in CMY space (white = 0 and black = 1), the results may not be intuitive. For example, ORing a white object with a black object in RGB space yields a white object. This is the same as ANDing the two objects in CMY space. It must be remem­bered that the printer operates in something similar to a CMY space and inverts the bits and reverses the order.

are placed for both PCL and HP-GL/2 operation.
Printer-Specific Differences 2-25
The example shown in Figure 2-1 illustrates the concepts of the two models. Assume a rectangle extends from coordinate position (1,1) to position (3,4). As shown below, each model produces a different result. (Since PCL printers print only at intersections, grid centered pixel placement is implemented as shown on the right.)
Figure 2-1. Pixel Placement
Note The grid centered method is used by Microsoft Windows.
2-26 Printer-Specific Differences
The grid centered model produces a rectangle that is one dot row thinner and one dot row shorter than the grid intersection model. The grid intersection model is the PCL default.
Placement Variations
PCL and HP-GL/2 (see following pages for HP-GL/2 pixel placement command description) provide two pixel placement modes: grid intersection (the default) and grid centered. Grid intersection places pixels on the intersections of the grid (see Figure 2-2). Grid centered places pixels in the center of the grid. In Figure 2-2, a rectangle extends from position (1,1) to (3,4). The grid centered model produces a rectangle one dot thinner and one dot shorter then the grid intersection model.
When rectangular area fills are used and grid intersection is used, an overlapping of pixels can occur if rectangular area fills are placed adjacent to one another (as shown below). Depending on the raster operation presently in effect, this overlap can produce undesirable results in the final printed image. To avoid this problem, use the grid centered method.
Note Since PCL printers print only at intersections, grid centered
is implemented as shown on the right.

both HP-GL/2 and PCL operation. The PP command is not defaulted by an IN command.
Merge Control
Command (HP-GL/2)
The Merge Control (MC) command specifies the raster operation (ROP’s) to be performed in HP-GL/2. Raster Operations specify how source, destination, and patterns are combined to produce final images. This command supports all 256 Microsoft Windows ternary (ROP3) raster-operation codes.

opcode value is sent, printer sets ROP to 168. If opcode is out of range (some value other then 0-255), the command is ignored and the default ROP of 252 is used. (For example: MC1,60; MC1,60-; MC1,+60; MC1,60+; all set the ROP to 60; however, MC1,-60; or MC1,300; set the ROP to the default value (252).

Notes This command is the HP-GL/2 version of the PCL Logical
Operation command. This command sets a ROP value which affects not only
HP-GL/2 operation but also the PCL ROP value. The MC command is defaulted by an IN command.
Printer-Specific Differences 2-29
Note When using the MC command, some pattern types will not
produce the expected ROP result. This only occurs when using the FT (Fill Type) command pattern types 1, 2, 3, and 4, and the ROP includes an XOR operation. (This problem is due to the fact that these patterns are the result of a vector operation and do not produce raster data for use by a ROP operation.) All other Fill Type command patterns (types, 10, 11, 21, or 22) operate as expected.
opcode
The operation code (opcode) specifies the logical operations that are performed on a source, destination, and patterned image prior to drawing the final image. The opcodes are created by listing all possible combinations of a single pattern, source and destination pixel, and constructing the desired final pixel values. The following table shows three common opcodes (also see Table 2-6).

HP LaserJet 4P and 4MP Printers
The HP LaserJet 4P printer is the follow-on to the HP LaserJet IIIP printer. The HP LaserJet 4MP printer is the multi-platform (PostScript) version of the 4P printer. PCL operation and the internal fonts in these two printers are identical to that of the HP LaserJet 4ML printer. The 4P and 4MP printers have a control panel unlike the 4L and 4ML printers. Refer to Table 1-1, PCL Feature Support Matrix, for the commands these printers support and to Chapter 3, “Internal Typefaces/Fonts and Symbol Sets,” for font support information.

HP LaserJet 4PJ Printer
The HP LaserJet 4PJ printer is a modified version of the HP LaserJet 4P printer designed specifically for the Japanese market. The enhanced PCL 5 printer language in this printer includes all of the PCL 5 features of the HP LaserJet 4P, plus special features which specifically support the Asian printing market. These features include large font support, support for vertical printing, and the ESC/P printer language. T able 2-8 lists the PCL feature additions for this printer.

Descriptions of the Text Parsing Method Command, Character Text Path Direction Command, and Font Format 16 are provided in the following paragraphs. Following
that, a “LaserJet 4PJ Programming Tips” section offers examples and tips for performing specific tasks using PCL 5.
Text Parsing Method
Command
The Text Parsing Method command informs the PCL parser whether character codes should be interpreted as 1-byte or 2-byte character codes as described below.
?&t#P
# = 0, 1 - All character codes are processed as one-byte characters.
21 - Character codes are processed as one-byte or two-byte characters as described below.
31 - Character codes are processed as one-byte or two-byte characters as described below.
38 - Character codes are processed as one-byte or two-byte characters as described below.
Default = 0 or 31 (if the default symbol set is WIN31J, the value is 31; otherwise it is 0)
Range = 0, 1, 21, 31, 38
If the value field is 21, character codes in the range 0x21-0xFF are processed as the first byte of a two-byte character. The following byte is processed as the second byte of the two-byte character. All character codes outside this range are processed as one-byte values. This method can be used for parsing characters in Asian seven-bit encoding specifications, including JIS X0208 (Japan), GB 2312-80 (China), and KS C 5601-1992 (Korea).
If the value field is 31, character codes in the range 0x81-0x9F and 0xE0-0xFC are processed as the first byte of a two-byte character. The following byte is processed as the second byte of the two-byte character. All character codes outside this range are processed as one-byte values. This
Printer-Specific Differences 2-33
method can be used for parsing characters in the Shift-JIS encoding specification.
If the value field is 38, character codes in the range 0x80-0xFF are processed as the first byte of a two-byte character. The following byte is processed as the second byte of the two-byte character. All character codes outside this range are processed as one-byte values. This method can be used for parsing Asian eight-bit encoding specifications, such as the Big Five and TCA encoding specifications (Taiwan), and KS C 5601-1992 and GB 2312-80, which can be either 7 or 8 bit.
Character Text Path
Direction Command
This command allows the user to vertically rotate text for use in vertical writing applications.
?&c#T
# = 0 - Horizontal printing –1 - Vertical rotated printing
Default = 0 Range = 0, 1
Using ?&c0T, the printer’s current active position (CAP) advances left to right, and linefeed advances top to bottom with horizontal, upright characters.
Using ?&c–1T, the following actions occur:
Full-width characters in large fonts are rotated counter-clockwise 90 degrees (“vertical rotated” characters).
Vertical substitutes are made for characters which change their appearance, orientation, or positioning when written vertically.
All other characters are unaffected by this setting. The vertical-rotated printing mode (?&c-1T) has the
effect of transforming a portrait page with horizontal text into a landscape page with vertical text. The PCL Print Direction command can be used to achieve other text orientations.
2-34 Printer-Specific Differences
Vertical substitution characters are those characters which change their appearance, orientation, or positioning when written vertically. Examples in Japanese fonts include parentheses, brackets, punctuation and small kana. In the example above, the two small characters are replaced with vertical substitutes. Vertical substitution characters are accessed through the Vertical Substitutes Character Segment, which is described in more detail later in this chapter.
Font Header
Format 16
The HP LaserJet 4PJ printer provides support for large fonts. Large fonts, such as the MS Mincho and MS Gothic fonts supplied in the printer, are fonts which are bound to large symbol sets. The LaserJet 4PJ printer supports a new font header to accomodate large bound fonts. New segments are provided for support of vertical substitutes, galley characters, typeface strings, and character enhancements.
The Font Header Command, described beginning on page 11-6 of the PCL 5 Printer Language Technical Reference Manual, has several different header formats. The support of large fonts adds Font Header Format 16 (Universal Font Header). Font Header Format 16 is identical in structure to format 15 (Universal Scalable Font Header) except that the size field for data segments has been enlarged from 16 bits to 32 bits, and a new Font Type has been added for large fonts (Font Type 3).
Printer-Specific Differences 2-35
New Font Format
Header Segments
For the HP LaserJet 4PJ printer, Font Header Format 15 has been extended to include optional data segments for supporting galley characters, typeface strings, and character enhancements. Font Format 16 supports these segments plus optional segments for supporting vertical substitution and a vertical rotation offset. (Segmented Font Data is described beginning on page 11-45 of the PCL 5 Printer Language Technical Reference Manual.)
Galley Character Segment
If an application requests a character that does not exist within the current font, the printer checks the Galley Character Segment for a substitute character to print.
Vertical Substitution Character Segment
The Vertical Substitution Character Segment is used to identify vertical substitute glyphs for characters which change their appearance, orientation, or positioning when written vertically.
Typeface String Segment
The Typeface String Segment allows names of permanent downloaded fonts to be displayed, using non-Latin characters, in the appropriate typeface on the Typeface List.
2-36 Printer-Specific Differences
Vertical Rotation Segment
When the character text path direction is set to vertical rotation, full-width characters are rotated counter-clockwise 90°. The Vertical Rotation Segment sets the point around which the character rotates, so that character alignment is compatible with the way Windows 3.1J rotates characters.
Character Enhancement Segment
The HP LaserJet 4PJ printer can apply pseudo-bold and pseudo-italic enhancements to MS Mincho, MS Gothic, and certain downloaded T rueType fonts. This segment is used to indicate that a particular downloaded font is able to have these character enhancements applied.

Data Segment Size
The Data Segment Size indicates the number of bytes in the immediately following Data Segment. The size of this field is 4 bytes for Font Format 16 fonts, and 2 bytes for Font Format 15 fonts. The rest of the data segments are identical for both font formats.
Galley Character Segment
If an application requests a character that does not exist within the current font, the printer checks the Galley Character Segment for a substitute character to print instead. The Galley Character Segment specifies the character codes of the substitute characters to be printed. A different galley character can be specified for different regions of the symbol set. For example, this segment can be set up so that an asterisk prints when a non-existent character is selected in the region 0x81 - 0x9F, and a question mark for characters in the region 0xE0-0xFC.

Region #x Lower Right Character Code (UI).
Character code defining lower right corner of Region #x. Region #x Galley Character (UI). Character code of

If the value of the galley character field is 0xFFFF, then if the font contains a missing character glyph, that glyph is printed. The missing character glyph can be downloaded using the PCL Download Character command with a character code = 0xFFFF and a glyph ID = 0.
If both the character specified by the original character code and by the galley character code are missing, the CAP is advanced in accordance with previous PCL rules for missing characters, that is, it is advanced according to the current setting of HMI (Horizontal Motion Index).
The Galley Character Segment will be invalid if the format number is not supported or if the segment size declared in the Segment Size field is larger or smaller than required for the number of regions (N). If the segment is invalid, the font download will be ignored.
Galley Character Segments can be downloaded with any Font Format 15 or 16 font, regardless of font type.
The Galley Character Segment can be used to implement a requirement of the Microsoft Windows Version 3.1, Japanese
Version, Microsoft Standard Character Set Specification
(March 11, 1993), which states “when there is an output request for a character of a specified typeface, even if the glyph corresponding to the specified character code does not
Printer-Specific Differences 2-39
exist, some glyph data will be output. For double-byte characters, the glyph of the default character defined for the given T rueType font is used. For single-byte characters, the glyph at 0xA5 (small dot, U+FF65) is used.”
The following table shows a Galley Character Segment which follows the Japanese Windows specification.

2-40 Printer-Specific Differences
In this example segment, there is one galley character region. This region is applied to all one-byte characters (character codes 0x0000-0x00FF); any missing character in this region is replaced with the character at character code location 0x00A5. Any missing characters falling into this region (e.g. character codes 0x0100 - 0xFFFF) are replaced with the default galley character. Since in this example the Default Galley Character field = 0xFFFF, the missing character glyph is printed if it is present in the font.
Vertical Substitution Segment
The Vertical Substitution Segment contains pairs of glyph IDs. Each pair specifies the horizontal and vertical glyph ID for a character. The segment can be built directly from a TrueType mort table which contains a vertical substitution array. The segment definition is shown in the table below.

The Horizontal Glyph ID field is used by TrueType as an ID number for the horizontal glyph data associated with a given character. The Vertical Glyph ID field contains the ID number for the vertical glyph data associated with the same character.
The vertical glyphs can be downloaded using the PCL Character Definition Command using a character code = 0xFFFF.
A TrueType mort table typically contains a header of 76 bytes, followed by the vertical substitution array which follows the segment format described here. However, the mort table header is designed to be variable-length, and the location of the vertical substitution data may be located elsewhere in mort tables in future fonts.
If the Font Type is not Type 3 (16-bit fonts), this data segment is ignored.
Printer-Specific Differences 2-41
If the value pairs are not sorted by horizontal glyph ID, the data segment is invalid. If the End of Table mark #1 is not 0xFFFF, the data segment is invalid. The location of the end of the table is determined using the Data Segment Size field. If the segment is invalid, the font download is ignored.
Typeface String Segment
The purpose of this segment is to provide a substitute string to print for a permanent downloaded font when doing a PCL Typeface List printout. It has the following structure:

Embedded Font Name Flag (UB)—A zero value in this field is used to indicate that the ASCII name of the font (from the Font Name field) should be printed in addition to the substitute string. A non-zero value is used to indicate that only the substitute string should be printed.
Substitute String Length (UB)—the number of UI characters in the Substitute String Character List.
Substitute String Character List (array of UI)—the characters which make up the substitute string. Each character is represented as a UI value. If the font is a bound font, then the values are accessed by their character codes values; if the font is unbound, then the Unicode index numbers (see Appendix D) are used.
The Typeface String Segment will be invalid if the Data Segment Size declared in the Data Segment Size field is larger or smaller than required for substitute string length, or if the Data Segment Size is an odd number of bytes. If the segment is invalid, the font download will be ignored.
Typeface String Segments can be downloaded with any Font Format 15 or Font Format 16 font, regardless of font type.
The following tables are examples of Typeface String Segments for two downloaded fonts. The first is for MS Mincho, and has the embedded font name flag set to true. The second is for MS Gothic, and has the embedded font name flag set to false.

Programming Tips
This section provides programming tips concerning specific considerations for the HP LaserJet 4PJ printer. This section covers general print job initialization, font metric calculation, vertical writing, and other issues which are pertinent to printing Japanese text on the HP LaserJet 4PJ printer using PCL 5.
General Print Job Initialization
This example demonstrates the general print job initialization procedure for the HP LaserJet 4PJ printer, which is slightly different than that used for other HP LaserJet printers.
Output from pre-LaserJet 4PJ PCL drivers (for example, a HP LaserJet 4P driver) will only print correctly on the HP LaserJet 4PJ printer if the default PCL symbol set is set to a value other than the Japanese Windows 3.1 (Win3.1J) symbol set. This is because the default PCL text parsing method is set based on the default PCL symbol set. When the default PCL symbol set is set to Win3.1J, the default text parsing method is Shift-JIS parsing; for any other value, such as Roman-8, the default text parsing method is 1-byte parsing. To set the default PCL symbol set value, use PJL or the control panel.
The first example given here is nearly identical to the initialization used for other HP LaserJet 4 family printers. The only difference is that it includes a PJL command to set the default PCL symbol set to Roman-8.
?%-12345X@PJL<CR><LF> @PJL SET RESOLUTION=600<CR><LF> @PJL PAGEPROTECT=OFF<CR><LF> @PJL RET=MEDIUM<CR><LF> @PJL COMMENT *** This command is added *** @PJL SET LPARM:PCL SYMSET=ROMAN8<CR><LF> @PJL ENTER LANGUAGE=PCL<CR><LF>
?E?&l1x1s1h2a0o8c6e54F?&a5L?(0U?(s1p9vs3b41 ~01T
The commands in the above example are explained in more detail in the PCL 5 and PJL technical reference manuals.
Printer-Specific Differences 2-49
The second example given here initializes a PCL 5 print job for printing Japanese text. The major differences from the previous example are that it specifies A4 paper, initializes the text parsing method to Shift-JIS, selects Win3.1J as the primary symbol set, selects MS-Mincho as the primary font.
?%-12345X@PJL<CR><LF> @PJL SET RESOLUTION=600<CR><LF> @PJL PAGEPROTECT=OFF<CR><LF> @PJL RET=MEDIUM<CR><LF> @PJL ENTER LANGUAGE=PCL<CR><LF>
?E?&l1x1h26a0o8c6e60F?&a5L?&t31P?(19K ~?(s1p10v0s0b28752T
The last line (2 lines, as shown) in the above example is a PCL 5 initialization string. This set of commands resets the printer, specifies 1 copy, specifies the paper tray as a paper source, chooses A4-size paper, selects portrait orientation, VMI=8 (6LPI), sets top margin to 6 lines, selects a text length of 60 lines, a 5-column left margin, Shift-JIS parsing, WIN3.1J symbol set, and a proportional, 10-point, upright, text-weight MS-Mincho font.
After the PCL print data, the following commands would be used to complete the job:
?E?%-12345X
2-50 Printer-Specific Differences
Font Metric Calculation
Accurate character placement relies on the ability to predict character width and height. As a character’s point size changes, so does its width and height. (CAP displacement, the distance the CAP moves for vertically rotated text, is a full-width calculation.)
In proportionally spaced fonts, character widths also vary from character to character within the font. Variable character widths add complexity to maintaining accurate line widths, page breaks, or WYSIWYG operation. To support most proportionally spaced fonts, font metrics must be extracted from the font metric files.
In the MS-Mincho and MS-Gothic fonts provided in the HP LaserJet 4PJ, font metric calculation is somewhat easier than for the Latin-based fonts. Width calculations are easier because all characters of these fonts conform to one of two different character widths at a particular point size. The characters are either considered full-width or half­width. One-byte characters are always half-width and two-byte characters are always full-width.
Full-width characters occupy the entire EM width at a particular point size. Half-width characters occupy half of an EM width. The following equations show how to calculate the EM width and character widths for a full-width and a half-width character.
ppem = round (DeviceResolution * PointSize/72) FullWidthDeltaX = round (ppem * PCLUnits/ DeviceResolut ion) HalfWidthDeltaX=round ((ppem/2) * PCLUnits/DeviceResolution)
where:
ppem = EM width in pixels DeviceResolution = current device resolution in dots per inch
(600 or 300dpi) PointSize = point size requested FullWidthDeltaX = character width of full-width character in PCL
Units HalfWidthDeltaX = character width of half-width character in PCL
Units PCLUnits = PCL Units
The PCL Unit of measure is explained in more detail in the PCL 5 Technical Reference Manual. The default PCL Unit size is 1/300th of an inch, but the Unit of Measure command can be used to set the PCL Unit size to other values.
Note that HalfWidthDeltaX may not be exactly half of
FullWidthDeltaX because of rounding. For example, if FullWidthDeltaX = round(99.0) = 99, then the
corresponding HalfWidthDeltaX = round(99.0/2) = round(49.5) = 50.
Printer-Specific Differences 2-51
Character Enhancements
The HP LaserJet 4PJ printer supports PCL pseudo-bold and pseudo-italic character enhancements. These enhancements can be applied to the internal MS-Mincho and MS-Gothic fonts. They can also be applied to a TrueType soft font if a suitable “Character Enhancement” Segment is downloaded with the font header.
The enhancements are selected using PCL font selection commands. The pseudo-italic enhancement can be selected using the Style command. The pseudo-bold enhancement can be selected using the Stroke Weight command. The bold levels which can be applied to the internal MS-Mincho and MS-Gothic fonts are Semi Bold, Demi Bold, Bold, and Extra Bold. For example, to select a 10-point, Extra Bold, Italic, MS-Mincho font, use the following PCL command:
?(19K?(s1p10v1s4b28752T
In the above command, Italics style (1s) and Extra Bold weight (4b) are selected. Since there is not an Extra Bold Italic MS-Mincho font resident in the printer, pseudo-italics and pseudo-bolding algorithms are applied to characters printed from the regular MS-Mincho font.
If a soft font is selected using the “Font Selection by ID” command (e.g. ?(#X ), the font is selected without any character enhancements applied. To select a soft font by ID with character enhancements, first select the font by ID, then select the desired attributes. For example, assume a soft font is downloaded with ID = 1 and a Character Enhancement Segment indicating that pseudo-bold and pseudo-italics character enhancements can be applied. The following command can be used to select that font with those enhancements:
?(1X?(s1s3B
Other font effects, such as character shadowing, strike­through, and gray-shading can be accomplished using the print model.
2-52 Printer-Specific Differences
Note HP-GL/2 as implemented in HP LaserJet printers has no
mechanism for parsing 2-byte characters. Therefore, HP-GL/2 character transformations (e.g. SI and SR commands) cannot be applied to these characters.
Vertical Writing
Vertical writing can be accomplished using the vertical rotated (“-1”) mode of the Character Text Path command (?&c-1T). When using a vertical rotated text path direction, full-width characters are rotated and printed “on their sides.” All other characters are unaffected and the CAP is still advanced in the horizontal direction. The “-1” mode has the effect of transforming a portrait page with horizontal full-width characters into a landscape page with vertical full-width characters. This can be combined with the Print Direction command (?&a#P) to achieve the desired text orientation (e.g. portrait, landscape, reverse portrait, or reverse landscape).
An example of horizontal and vertical rotated writing is shown below. The first line of text is horizontal writing and the second line is vertical rotated writing. Note that the “~” character is replaced with a vertical substitute on the second line. The C program that follows was used to generate the PCL commands for this example.

Printing Ruby Characters (Furigana)
Ruby characters, also known in Japanese as furigana, are small characters typically used as an aid in kanji pronunciation. Ruby characters are usually (but not always) hiragana. They are generally placed above the corresponding kanji in horizontal writing and to the right in vertical writing. Ruby characters can be generated using font scaling and cursor positioning commands.
An example of ruby characters is shown below. In this example, the ruby characters are printed at one-third the size of the kanji. The C program that follows was used to generate the PCL commands for this example.
#include <stdio.h> #include <fcntl.h> #define KANJITXT "\225\127\226\173" #define RUBYTXT "\202\320\202\345\202\244 \202\331\202\361 " FILE *prn; main() { int point_size=72; prn = fopen("lpt1","wb"); /* open lpt1 for writing */ fprintf(prn,"\33%%-12345X"); /* send UEL to get to PJL */ fprintf(prn,"@PJL ENTER LANGUAGE=PCL\n"); /* Enter PCL */ fprintf(prn,"\33E"); /* EscE to reset printer */ fprintf(prn,"\33&t31P"); /* text parsing = Shift-JIS */ fprintf(prn,"\33(19K"); /* symbol set = Win3.1J */ fprintf(prn,"\33(s1p%dv0s0b28752T",point_size); /* MS-Mincho */ fprintf(prn,"\33*p300x400Y"); /* set cursor position */ fprintf(prn,KANJITXT); /* print kanji characters */ fprintf(prn,"\33(s%dV",point_size/3); /*furigana point size */ fprintf(prn,"\33*p300x%dY",400-4*point_size);/*cursor position*/ fprintf(prn,RUBYTXT); /* print ruby characters */ fprintf(prn,"\f"); /* formfeed */ fprintf(prn,"\33%%-12345X"); /* send UEL to get to PJL */ }

Vertical Underlining
In Japanese writing, vertical underlines are placed to the right of vertical columns of text. This can be accomplished in PCL 5 using the Fill Rectangular Area command.
An underline is simply a long thin black-filled box. The length of the underline depends on the length of the text to be underlined.
An example of vertical underlining is shown below. The C program that follows was used to generate the PCL commands for this example.

Vertical Clusters
Vertical clusters are groups of two or three narrow characters side-by-side in a vertical line of text. Vertical clusters containing half-width characters can be created by using a combination of print direction and cursor positioning commands.
An example of vertical clusters is shown below. The C program that follows was used to generate the PCL commands for this example. In this example, two half­width characters (e.g. 2-digit numbers) were printed as vertical clusters.

HP LaserJet 4 Plus and 4M Plus Printers
2-60 Printer-Specific Differences
HP LaserJet 4 Plus and 4M Plus printers are performance-enhanced follow-on products for HP LaserJet 4 and 4M printers, respectively. The HP LaserJet 4M Plus printer is the multi-platform (PostScript) version of the LaserJet 4 Plus printer.
In addition to extra speed, these printers also have the following added features which are not controlled using PCL:
Memory Enhancement technology (MEt), which uses memory-saving techniques to better utilize available memory (refer to Chapter 5 “Memory Usage” for additional information). MEt is not controlled using PCL.
Resource saving, as in the LaserJet 4Si printer. Resource saving allows saving information for the current language (PCL or PostScript) when switching to another
language. If resource saving is enabled, all the permanent fonts, macros, and user-defined patterns plus other miscellaneous data is saved in a reserved portion of printer memory. This data is stored until the language is enabled again. When the language is re-enabled, the stored data is made available for use. Resource saving is enabled from the control panel or using PJL—no PCL commands are required for this operation.
EconoMode, a feature supported by HP LaserJet 4L and 4P printers, allows the user to reduce the amount of toner used by removing about 75% of the dots from the printed page. EconoMode is selected using PJL or from the control panel—it is not controlled using PCL.
Powersave mode, which minimizes power consumption when the printer is sitting idle. The amount of idle time required before the printer goes into powersave mode is configurable using the control panel or PJL.
PCL operation in these two printers is almost identical to that of HP LaserJet 4 and 4M printers, except HP LaserJet 4 Plus and 4M Plus printers support Logical Operations (ROP3) as explained in the HP LaserJet 4ML printer section in this chapter. In addition, the internal fonts in HP LaserJet Plus and 4M Plus printers support the Latin 2 and Latin 5 symbol sets for all typefaces (in the HP LaserJet 4, 4M, 4Si, and 4SiMx, only 15 of the 35 Intellifont typefaces support these symbol sets). Refer to Table 1-1, PCL Feature Support Matrix, for the commands these printers support and to Chapter 3, “Internal Typefaces/Fonts and Symbol Sets,” for font support information.
Printer-Specific Differences 2-61
HP LaserJet 4V and 4MV Printers
HP LaserJet 4V and 4MV printers print at speeds up to 16 pages per minute and handle many paper sizes including 11"x17" paper. The HP LaserJet 4MV is the multi-platform (PostScript) version of the HP LaserJet 4V printer.
The HP LaserJet 4V/4MV PCL 5 feature set is similar to that of the HP LaserJet 4 Plus/4M Plus printers, with the addition of wide format media support. As an option, the printer can also support Japanese printing as does the HP LaserJet 4PJ printer , including the following PCL enhancements:
Font header support for large bitmap fonts Text parsing method Character text path direction Japanese media/postcard support Japanese fonts (large fonts)
As with HP LaserJet 4Plus and 4M Plus printers, the LaserJet 4V and 4MV printers support the following added features which are not controlled using PCL:
Memory Enhancement technology (MEt) Resource saving EconoMode Powersave mode
Refer to T able 1-1, the PCL Feature Support Matrix, for the commands these printers support, and to Chapter 3, “Internal Typefaces/Fonts and Symbol Sets,” for font support information.

Font Header Format 16 Bitmap Font Support
Font Header Format 16 was introduced with the HP LaserJet 4PJ for downloading large TrueType fonts. For the HP LaserJet 4V, Font Header Format 16 has been extended to support large bitmap fonts as well. The Font Header command ( ? ) s # W [font header data] ) is used to download font header data to the printer.
A large font is a bound font with character codes that are not limited to 8-bit values. For this reason a large font is sometimes called a 16-bit font.
Font Header Format Font Header Format 16 was introduced because some font
data segments in large fonts could be larger than 65535 bytes, and this was not supported by Font Header Form at 15. The structures of Format 15 and Format 16 are identical with the exception of the Segment Size field in the Segmented Font Data format. Table 2-10 below shows the Format 15 and Format 16 Font Header format. Table 2-11 shows the Format 15 Segmented Font Data format. Table 2-12 shows the Format 16 Segmented Font Data format. Note that Format 15 does not support bitmap fonts.
