HP 5100tn Printer Job Language - Technical Reference Manual - Page 71

Key Points to Remember About Environments When using PJL to set the printer to a desired state, remember the following points. At the beginning of a PJL job, the current feature settings are the same as the control panel values or those features set with the DEFAULT command. When a printer language is entered, the current feature settings (Modified Print Environment) become the same as the PJL Current Environment. From this starting point, the printer language commands modify the feature settings. Printer language commands override all other settings. The PJL Current Environment settings can be changed using the SET command. These settings take effect until the next PJL reset condition. The control panel settings (User Default Environment) can be changed using the control panel or the DEFAULT command. In printers without a control panel, the default settings are modified with only the DEFAULT command. The Modified Print Environment settings are changed using printer language commands. These settings take effect for the duration of the printer language job. After a printer language-specific reset, such as E for PCL, the PJL Current Environment feature settings are loaded into the Modified Print Environment. If the SET command is used in a PJL job, always use the PJL RESET command after the job is completed. Environment Commands 6-9
