Commands That Affect Printer Memory Printers that reconfigure memory due to PJL commands: HP LaserJet 4, 4M, 4 Plus, 4M Plus, 4V, 4MV, 4Si, 4SiMx, 4ML, 4P, 4MP, 4PJ, 4LJ Pro, 4LC, 4000 series, 5, 5M, 5P, 5MP, 6L, 6P, 6MP, 5Si, 5SiMx, 5Si Mopier, HP Color LaserJet, HP Color LaserJet 5, 5M, LaserJet 1100 series, 2100 series, 4500 series, 5000 series, 8000 series, 8100 series, 8500 series Four conditions may cause the printer to reconfigure user memory: • When the printer language changes, either implicitly or explicitly by using the ENTER LANGUAGE command (except when resource saving is enabled). • When the page protection setting changes, using the SET or DEFAULT commands, or when the printer is reset using the RESET or INITIALIZE commands or by using the control panel. • When the resolution is changed using either the SET or DEFAULT commands, or by using the control panel. • When changing the I/O buffering or resource saving settings. Reconfiguring printer memory erases all volatile personality-specific resource information, including downloaded fonts, PCL macros, and PostScript dictionaries (however no I/O data is lost). Memory can be reconfigured only when these conditions actually change the page protection, resolution, or printer language status. For example, if the resolution is at 600 dpi and an application sends the @PJL SET RESOLUTION = 600 command, memory is not reconfigured. If resource saving is enabled, memory is reconfigured, but all volatile personality-specific resource information (such as fonts, macros, and PostScript dictionaries) are not lost (see "Resource Saving" below). If resource saving is disabled, these resources are erased. A-46 Product-Specific Feature Support EN
