INQUIRE Command The INQUIRE command is used to obtain the current value of a specified PJL environment variable, including read-only variables. Use the INQUIRE command to find out the setting for a particular PJL feature, such as ORIENTATION. Syntax: @PJL INQUIRE [LPARM : personality | ~IPARM : port] variable [] Response Syntax: @PJL INQUIRE [LPARM:personality | ~IPARM:port] variable value • LPARM : personality - This optional parameter is used to inquire about printer language-specific environment variables. For example, you can use this option to request the current PCL symbol set stored in the PJL Current Environment. PCL is a valid personality. Other personalities, such as POSTSCRIPT, can be added as hardware options. Use the @PJL INFO CONFIG command to request the personalities installed in a particular printer. • IPARM : port - This optional parameter is used to set port-specific variables. The HP LaserJet 4PJ is the only printer which supports port-specific variables. The IPARM : port option must be used when setting port-specific variables. Valid values for port for the HP LaserJet 4PJ printer are SERIAL and PARALLEL. • variable - This parameter specifies the environment variable you want. For example, the INQUIRE RET command requests the current value of the Resolution Enhancement technology feature. See Appendix A for a list of valid variables for each printer.
