Parameters: Parameter personality port variable Variable Names PCL ESCP POSTSCRIPT (Other personalities may also be supported) PARALLEL SERIAL Supported on LaserJet 4PJ only Valid variables for each printer are listed in Appendix A. Comments: The DEFAULT command enables you to specify default values for either general variables, which are used by all personalities, or personality-specific variables. All personality-specific variables, such as the default PCL symbol set or the PostScript-specific variable PRTPSERRS, must be set using this option. Variables that are not personality-specific cannot be set using the LPARM : personality 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. Default values set with this command affect the printer control panel value and the feature setting stored in non-volatile RAM (in those printers that have a control panel and NVRAM). However, these values do not affect the print environment until a PJL reset condition occurs (see "PJL Reset Conditions" for a list of printer events that constitute a PJL reset). Consequently, if you want the default values to take effect immediately, send a RESET command after sending the DEFAULT command(s). A separate DEFAULT command must be sent for each environment variable you specify. The command may be used to set any environment variable except the read-only variables. See the "Environment Variables" section of this chapter for a description of each environment variable. 6-34 Environment Commands
