Note Comments: The SET command enables you to specify either general variables which are used by all personalities, or printer language-specific variables. Printer language-specific variables must be specified using the LPARM : personality option. Features that are not printer language-specific cannot be specified with the LPARM option. All port-specific variables must be set using the IPARM : port option. Variables that are not port-specific cannot be set using the IPARM : port option. Values modified with the SET command do not affect the User Default Environment values. Feature settings changed with the SET command are valid until the next PJL reset condition. A separate SET command must be sent for each environment variable you specify. The command may be used to set any environment variable except CPLOCK, DISKLOCK, PASSWORD, and the read-only variables. See the "Environment Variables" section of this chapter for a discussion of each environment variable. If the SET command is used in a job, use the RESET command after the job to reset features to the User Default (control panel) values. See the following example for a demonstration of how to use the RESET command to "clean up" after using SET. EN Environment Commands 6-47
