Changing Environment Settings The following scenario elaborates on how the print environment changes during printer operation. The "number of copies" feature is used to show feature changes as events occur. 1. The first time the printer is turned on after it leaves the factory (or after the INITIALIZE command), the number of copies feature is set to the factory default value of 1 copy. 2. At any point following the initial power-on or the INITIALIZE command, the number of copies feature can be set using the DEFAULT COPIES command in a PJL job or by changing the COPIES = setting on the control panel. This changes the User Default Environment setting to a new value, such as number of copies = 3. The User Default Environment values are not loaded into the PJL Current Environment until the next PJL reset condition occurs. (For printers with control panels, if the printer is currently not processing a job while the feature is changed from the control panel, the printer treats the feature change as a PJL reset condition and loads the newly changed value into non-volatile RAM.) 3. If the PJL job uses the SET COPIES = 5 command to change the number of copies, the PJL Current Environment value changes to the selected setting (for example, 5). Otherwise, the number of copies setting remains the same as set using the DEFAULT command or the control panel (in this example, 3). 4. If the printer language (such as PCL or PostScript) changes the number of copies setting to another value, such as 8, the newly specified printer language value overrides the PJL Current Environment value. If the printer has a control panel, however, it still displays the User Default Environment value set using the control panel keys or the DEFAULT command (3). 5. The next PJL reset condition defaults the number of copies setting to the value set from the control panel or by Environment Commands 6-5
