HP-PCL 5e or 5c Emulation
Terminology
Font
A font is a unique set of objects that has an ID and attributes (symbol set, spacing, pitch,
height, style, weight, and typeface number). A font is accessed by specifying a desired set
of attributes. The system selects the font that most closely matches these attributes from
the available set of fonts.
There are two types of fonts — bound and unbound. A bound font supports a single
symbol set. An unbound font supports multiple, but not all, symbol sets. With unbound
fonts, the symbol sets are organized into two groups — normal and Dingbats. All
downloaded fonts are bound, and all resident fonts (except Zapf Dingbats which supports
the Dingbats symbol set) support the group of normal symbol sets.
In the PCL 5e or 5c emulation, only fonts located in the current resource may be accessed
by a PCL font ID using the normal <ESC>(#X sequence. All other fonts (resident,
cartridge, or other) including those stored on the additional resources can be accessed only
by attributes.
Also, only objects stored in the current resource may be deleted directly by the PCL
language. Thus, unless explicitly removed, external fonts are always available to all PCL
jobs.
Font Index Number
In addition to its ID, a downloaded font also has a unique index number which is
automatically assigned by the printer when the font is downloaded. This index number
may change if new resources are added, but in practice it usually remains fixed. All
currently available PCL fonts (resident, cartridge, temporary, permanent, and external) are
listed with their font index numbers on the Advanced Status Page.
The font index number defines the default PCL font to be used if selectbyid is specified as
the default PCL font. Do not confuse the font index with the PCL font ID, a mechanism
used to identify downloaded fonts in the PCL language using the <ESC>(#X sequence.
There is no way to specify fonts by their font index numbers from within the PCL
language. Only the default PCL font is affected.
