Factory Default Environment User Default Environment PJL Current Environment Modified Print Environment (PrinterLanguage Specific) Stored permanently in printer memory-settings cannot be modified. Factory default settings cannot be read programmatically, but they are listed in the PCL 5 Comparison Guide. The User Default Environment is set to the factory default values when the printer initially is powered on-before printer commands are sent from an application or any control panel settings are changed. Stored in non-volatile RAM in printers that have it-can be changed using the DEFAULT command or control panel keys. The INITIALIZE command loads the Factory Default settings into the User Default Environment. User default settings can be read using the DINQUIRE command. Any PJL reset condition loads the User Default Environment feature settings into the PJL Current Environment. Always reflects the PJL-level settings currently in use. Stored in RAM-can be changed using SET command. These values override feature settings until the next PJL reset condition. The INITIALIZE command loads the Factory Default settings into the PJL Current Environment. PJL Current Environment settings can be read using the INQUIRE command. Active as soon as printer receives any printer language commands (such as PCL or PostScript commands). This environment contains all of the feature settings currently in effect at any point after a printer language is entered. Printer language resets (such as the E command in PCL), any printer language switch, or the ENTER command load the PJL Current Environment into the Modified Print Environment. Stored in RAM-can be changed using printer language commands (PCL, PostScript, and others). The printer language values override any PJL Current Environment feature for the duration of the printer language job (until the printer language is changed or a printer language-specific reset is executed). The Modified Print Environment settings can be read if the active printer language supports this capability. EN Environment Commands 6-7

Environment Commands 6-7

Factory Default

Environment

Stored permanently in printer memory

—

settings cannot be modified.

Factory default settings cannot be read programmatically, but they are listed in the

PCL 5 Comparison Guide

User Default

Environment

The User Default Environment is set to the factory default values when the printer

initially is powered on

—

before printer commands are sent from an application or any

control panel settings are changed.

Stored in non-volatile RAM in printers that have it

—

can be changed using the

DEFAULT command or control panel keys.

The INITIALIZE command loads the Factory Default settings into the User Default

Environment.

User default settings can be read using the DINQUIRE command.

PJL Current

Environment

Any PJL reset condition loads the User Default Environment feature settings into the

PJL Current Environment.

Always reflects the PJL-level settings currently in use.

Stored in RAM

—

can be changed using SET command. These values override

feature settings until the next PJL reset condition.

The INITIALIZE command loads the Factory Default settings into the PJL Current

Environment.

PJL Current Environment settings can be read using the INQUIRE command.

Modified Print

Environment

(Printer-

Language

Specific)

Active as soon as printer receives any printer language commands (such as PCL or

PostScript commands). This environment contains all of the feature settings

currently in effect at any point after a printer language is entered.

Printer language resets (such as the <ESC>E command in PCL), any printer

language switch, or the ENTER command load the PJL Current Environment into

the Modified Print Environment.

Stored in RAM

—

can be changed using printer language commands (PCL,

PostScript, and others). The printer language values override any PJL Current

Environment feature for the duration of the printer language job (until the printer

language is changed or a printer language-specific reset is executed).

The Modified Print Environment settings can be read if the active printer language

supports this capability.
