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
number 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 font
is affected.
Object
There are three types of PCL downloaded objects: temporary,
permanent, and external. Temporary objects reside on the current
resource and they are deleted either at the beginning and end of a
job (unless Retain Temporary is set to On or On Compatibility) or
when the system is reset (<ESC>E or receipt of Printer Job
Language). Permanent objects reside on the current resource and
