Non-Printing Mode Printing selected pages in a print job by sending the entire print job, the desired starting page number, and the ending page number. The PJL JOB command options START and END are used to provide the starting page number and the ending page number. When the printer processes the pages that are not printed, the printer is said to be in non-printing mode. Non-Volatile Memory Random Access Memory where contents are preserved when the printer is powered off (volatile RAM is memory where contents are not preserved when the device is powered off). Offline/Online Online is a condition during which the printer accepts data from the host computer. When the printer is online, the ON LINE light is lit. When offline, the printer cannot accept data from the host. Personality The printer firmware related to transforming a particular type of printer language data, like PCL or PostScript, into images that the printer's operating system can print. The printer uses different personalities (different firmware) to handle data from different printer languages. PCL and PostScript commands are each processed by separate firmware. New personalities can be added to some LaserJet printers using means such as cartridges or ROM SIMMs. PJL is not a personality (you cannot print using PJL). See "Personality Switching." Personality Switching The process of shutting down the current personality and activating the appropriate personality to process the next print job. For example, when the printer is processing PCL data, the PCL personality is activated; for PostScript data, the PostScript personality is activated. Glossary-4 EN
