Orientation 
The Orientation command (E
C&l#O) designates the position of the 
logical page with respect to the physical page. Earlier printers could 
only print bitmap fonts and raster graphics in the orientation for which 
they were designed. However, the HP LaserJet IID, IIP, 2000, and all 
PCL 5 HP LaserJet printers have the capability to automatically rotate 
bitmap fonts and raster graphics to match the page orientation; 
therefore, all fonts are available in all four page orientations and print 
directions. Whenever a scalable font is selected, it is created in the 
current orientation for printing. Refer to “Logical Page Orientation 
Command” and “Print Direction Command” in Chapter 5 for more 
information.

Font Selection Examples 
Bitmap, Fixed-Spaced Font 
This example illustrates how to select a primary, bitmap, Line Printer, 
fixed-spaced font with the following characteristics (note that all of the 
font characteristics are specified):
The following escape sequences can be sent to the printer to select a 
primary font with the above characteristics:
E
C(0UE
C(s0PE
C(s16.66HE
C(s8.5VE
C(s0SE
C(s0BE
C(s0T
The previous sequence can be shortened by combining sequences 
that have the same two characters following the E
C character:

Scalable, Proportional-Spaced Font 
This example illustrates how to select a primary, scalable, CG Times, 
proportional-spaced font with the following characteristics (note that 
all of the font characteristics are specified except pitch which is not 
required for a proportional font):
The following escape sequences can be sent to the printer to select a 
primary font with the above characteristics:
E
C(0UE
C(s1PE
C(s14.25VE
C(s0SE
C(s3BE
C(s4101T
Combining the above sequences results in:
E
C(0UE
C(s1p14.25v0s3b4101T
NotesIf an escape sequence does not contain a value field, the printer 
assumes a value of zero; therefore, the command E
C(sB can be sent 
to the printer instead of E
C(s0B.
Sending shortened font selection commands can result in selection of 
an unexpected font. This is due to failure to track previously specified 
characteristics and their selection priority in relation to the current font 
selection. Thus, it is recommended that all of the characteristics 
be sent to ensure that the correct font is selected.  CHARACTERISTIC VALUEESCAPE

Summary of Font Selection by Characteristic 
The following summarizes the procedure the printer uses to select a 
font. Selection by characteristic is an elimination process. The nine 
steps are performed in the following order:
NoteWhen the printer is in 300 dpi mode, any 600 dpi bitmaps are 
eliminated before the selection process begins.
1Symbol Set - if the specified symbol set exists, that symbol set is 
selected; otherwise, Roman-8 is selected.
2 Spacing - if proportional spacing is specified and available, 
proportional spacing is selected. If propor tional spacing is 
specified but is not available, fixed spacing is selected in the 
current pitch. (A proportionally-spaced font is always available 
in PCL 5 printers, but it may not be available in the specified 
symbol set.)
3Pitch - applies only to fixed spaced fonts. If fixed spacing is 
specified and available, fixed spacing in the specified pitch is 
selected.
Bitmap Fonts: For a fixed-space bitmap font, if the specified 
pitch is not available, the next greater available pitch is selected. 
If no greater pitch is available, the closest available lesser pitch is 
selected. If fixed spacing is specified but is not available, a 
proportional-spaced font is selected and the pitch characteristic is 
ignored.
Scalable Fonts: For a fixed-spaced scalable font, the pitch is 
used to calculate the appropriate height. The Height selection 
command is not required. The printer calculates the appropriate 
height to correspond to the pitch. The user’s height request is 
recorded in the printer’s font select table for later font selections, 
but is ignored for this selection. 
4 Height - the closest height available from the remaining fonts is 
selected. The closest height is in terms of absolute difference. All 
bitmap fonts whose heights are within a quarter point of the 
specified height are considered to have the specified height. 
						

							8-24   PCL Font SelectionEN
NoteFor proportionally-spaced scalable fonts, any specified height is 
available to the nearest quarter point. For fixed-spaced scalable fonts, 
the designated height is recorded, and the height is calculated from 
the requested pitch.
5Style - if the specified style is available in the remaining fonts, 
that style is selected; otherwise, this characteristic is ignored.
6 Stroke Weight - if the specified stroke weight is available in the 
remaining fonts, that stroke weight is selected.
If the specified stroke weight is greater than or equal to 0 and is 
not available, the next thicker available stroke weight is selected. 
If no thicker stroke weight is available, the closest available 
thinner stroke weight is selected.
If the specified stroke weight is less than 0 and is not available, 
the next thinner available stroke weight is selected. If no thinner 
stroke weight is available, the closest available thicker stroke 
weight is selected.
7 Typeface Family - if the requested typeface is available in the 
remaining fonts, that typeface is selected; otherwise, this 
characteristic is ignored.
8 Location - if after performing all the preceding steps, more than 
one font remains, the available font from the highest priority font 
location is selected. The priority of the font locations are: 
Priority of Locations
Soft Font (Lowest ID first)   Highest
Cartridge Font
1
1. In printers with two cartridge slots, one slot has priority over the other. Refer to 
Appendix E of the PCL 5 Comparison Guide for cartridge slot priority information 
for the different HP LaserJet printers.|
SIMM Font  |
Internal Font   Lowest 
						

							ENSummary of Font Selection by Characteristic 8-25 9 Orientation - for bitmap fonts the last criteria considered for the 
selection is its orientation. If two fonts still remain and match in all 
the above characteristics except orientation, that font which 
matches the current page orientation is selected.
If there is a soft font (highest priority location) available that 
matches all selection characteristics, but is not in the current 
orientation, and there is an identical font available in a cartridge 
or internal font (lower priority location) that is in the current 
orientation, the soft font is selected and rotated.  
						

							8-26   PCL Font SelectionEN
Font Selectionby ID Command 
Soft fonts can be specified using their associated ID numbers. (ID 
numbers are assigned to soft fonts using the Font ID command 
described in Chapter 9, Font Management).
E
C ( # X -   Designates soft font # as primary 
E
C ) # X -   Designates soft font # as secondary
#  =   font ID number 
Default =0
Range = 0 - 32767
If the designated font is present, the font is selected as the primary/ 
secondary font and all primary/secondary font characteristics in the 
printer’s Font Select Table are set to those of the selected font. 
However, if the selected font is proportionally spaced, the pitch 
characteristic is not changed.
If the designated font is not present, the current font is retained.
NotesIf a scalable font is selected using an ID number, send the Height or 
Pitch command (Height for proportional, Pitch for fixed) to specify the 
height or pitch; otherwise, the characteristic is determined by the 
value of the former font (as listed in the font select table).
If the font is a scalable typeface, symbol set is determined from the 
values contained in the printer’s font selection table. To specify a 
different symbol set, send a symbol set selection command prior to 
the Font Selection ID command.
For shared or multi-user environments, Hewlett-Packard recommends 
that soft fonts be selected by characteristics rather than ID number. 
						

							ENSelect Default Font Command 8-27
Examples
To specify the font associated with ID number 7 as the primary font, 
send:
E
C(7X
To specify the font associated with ID number 5 as the secondary 
font, send:
E
C)5X
Select Default Font Command 
The Default Font command sets all of the font characteristics to those 
of the user (control panel selected) default font.
E
C ( 3 @ -  Default primary font characteristics
E
C ) 3 @ -  Default secondary font characteristics
NoteIf the user default font is a proportionally-spaced font, the pitch 
characteristic is not affected by the default font command.
HP-GL/2 Font Selection 
In addition to selecting fonts using the PCL font selection commands, 
fonts can also be selected and printed in HP-GL/2 mode using the 
HP-GL/2 label commands (refer to Chapter 23, Character Group). 
The HP-GL/2 font selection commands allow you to label vector 
graphic images and to create some special effects with fonts not 
otherwise available. These special effects include printing outline 
fonts from fonts which are not outline style, printing mirror-images of 
fonts, and printing fonts on any angle on the logical page. Fonts can 
also be scaled using HP-GL/2 vector graphics, however this font 
scaling method is rather program intensive and not the recommended 
method (refer to “HP-GL/2 Vector Graphics” in Chapter 25 for 
additional information).

Transparent Print Data Command
The Transparent Print Data command provides printing access to 
those characters which the printer normally defines as unprintable. 
These characters include decimal character codes 0, 7-15, and 27.
E
C & p # X  [Transparent Print Data]
#  =Number of bytes of transparent print data. 
Default =N/A
Range = 0 - 32767
Each transparent print data byte is interpreted as a single character 
code. The appropriate character is printed if one exists; otherwise, a 
Space is processed. For example, control codes such as LF, CR, FF 
are treated as print data while in Transparent Print Data mode.
Example
Assuming the currently selected symbol set is PC-8, send the 
following to print musical notes (decimal code 14):
E
C&p1X [ASCII 14]
The brackets “[ ]” are provided for clarity and are not part of the 
command sequence.
NoteIn the ASCII symbol set, decimal 14 is the Shift Out control code (no 
printable character exists), however, in the PC-8 symbol set, decimal 
code 14 is also the musical notes character (printable from 
transparency mode). Refer to Appendix A for character codes for the 
various symbol sets.
