HP DeskJet 1200C and 1600C Printer Family Comments This sections explains some important points that should be considered when using PJL with the DeskJet 1200C and 1600C family printers. Support for the features described in this section varies. The HP DeskJet 1200C and 1600C family printers that support a particular feature are listed at the beginning of each feature description. Printer Language Switching Printers that support printer language switching: HP DeskJet 1200C, 1200CM, 1600C, 1600CM Printers that perform context switching automatically switch printer languages when both of the following conditions are met: • For the DeskJet 1200C and 1200CM: when the rear panel DIP switch is set in the "Context On" position. • For the DeskJet 1600C and 1600CM: when the PJL "CONTEXTSWITCH" environment variable is set to ON. • The print job contains printable data but does not contain a PJL ENTER LANGUAGE command immediately before the printable data. Under these conditions, the printer samples the incoming printable data and looks for indications of a particular printer language. Once it recognizes the printer language, the printer backs up to the beginning of the sampled print data and switches to the printer language determined to be most appropriate. Then the printer begins to parse the data in the newly selected printer language. A-52 Product-Specific Feature Support EN
