5-2 Languages Setting SmartSwitch for Different Interfaces You can customize your printer so that particular print jobs are sent to particular interfaces. For example, you may want to send all PostScript emulation jobs to the network interface and all PCL emulation jobs to the parallel interface. You can do so by choosing different languages for each interface from the printer operator panel or through MarkVision Professional and setting the selected language to On for the interface you want. See your printer documentation for more information. If you have turned off a particular language for an interface, but then decide to send a job to that interface using that language, you must begin the job with a PJL command to override the settings you made from the printer operator panel or through MarkVision Professional. For example, if you set PCL emulation to Off for the serial interface and later decide to send a job in that language through that interface, you must preface the job with a PJL command to override the Off setting. Be sure to end the job with a Universal Exit Language (UEL) command, which is described on page 3-2. Printer Job Language For details on Printer Job Language (PJL) and the PJL ENTER LANGUAGE command, see "ENTER LANGUAGE Command" on page 3-3.
