HP (Hewlett-Packard) QMS 1660 Printer User Manual


 
In addition to its ID, a downloaded font also has an unique index num-
ber 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.
There are three types of PCL downloaded objects:
Temporary
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
Permanent objects reside on the current resource and are
retained when the system is reset (<ESC>E or receipt of Printer
Job Language).
External
External objects reside on the additional resources.
All objects are temporary when first created. They can be made per-
manent objects through PCL commands. Both temporary or perma-
nent objects can become external objects when the current resource
is changed (for temporary objects Retain Temporary must be set to
On, True, or On Compatibility). External objects become permanent
