HP 5100tn Printer Job Language - Technical Reference Manual - Page 63

6 Environment Commands Introduction Hewlett-Packard printers have many features you can set using printer commands or by pressing control panel keys. Since previous jobs can change feature settings to unwanted values, applications should set printer features affecting the print job to a desired state at the beginning of the job. Setting features to a desired state is easily accomplished using a combination of PJL and printer language commands. This chapter describes sets of printer features known as print environments, and the PJL commands you use to set printer features to a desired state, such as: DEFAULT sets the default value for environment variables, storing these values in non-volatile RAM. INITIALIZE resets the current and default PJL variables to the factory default values. RESET resets the current PJL variables to the default values. SET sets an environment variable to a specified value until the next PJL reset condition. Note For a list of default feature settings, see Appendix A. Environment Commands 6-1
