General PJL Environment Variables (continued) Variable Description Sample Value Range PAGEPROTECT Page protection configuration. The OFF, LETTER, page protection feature reserves a LEGAL, A4, AUTO, block of printer memory to prevent ON printer overrun errors (error 21) when formatting very dense or complex images, especially HP-GL/2 images. The variable can be set to any legal value at any time, regardless of the current amount of free memory or the currently set resolution. When a job is sent, if there is not enough memory to print correctly with the current resolution and page protection configuration, the system temporarily overrides the resolution and/or page protect values to run the job. In these cases, the job may be printed at 300 dpi without page protection. When the page protection status is changed, memory is reconfigured and all downloaded fonts, PCL macros, and PostScript dictionaries are lost (however, no I/O data is lost). Refer to "Commands that Affect Printer Memory" in Appendix A. PALETTESOURCE Specifies how color settings are derived, either from the device's control-panel settings or through the software application.
