Font Index Number

In addition to its ID, a downloaded font also has an 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.

Object

There are three types of PCL downloaded objects:

nTemporary

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).

nPermanent

Permanent objects reside on the current resource and are retained when the system is reset (<ESC>E or receipt of Printer Job Language).

nExternal

External objects reside on the additional resources.

All objects are temporary when first created. They can be made permanent objects through PCL commands. Both temporary or permanent 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
