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. See the PCL 5 Emulation Technical Reference
Manual for information on what characterizes a PCL font.
There are two types of fonts—bound and unbound. A bound font sup-
ports 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 QMS PCL 5 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. Therefore, unless they are explicitly
removed, external fonts are always available to all PCL jobs.
Font Index Number
In addition to its ID, a downloaded font also has an unique index num-
ber that 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
