Methods of Printer Language Switching
There are three methods of switching printer languages, two of which
are supported by all PJL printers. All three methods are described
below:
• Explicit Switching. With explicit switching, the ENTER
LANGUAGE command is used to “explicitly” select the desired
printer language. This is the preferred switching method
because it ensures that the specified printer language is
always selected (see Figure 4-1).
• Implicit Switching. If the printer has a default printer
language configured, and the print job does not explicitly
select a printer language using the ENTER LANGUAGE
command, the printer automatically switches to the default
printer language. (See the User's Manual for each printer for
instructions about specifying a default printer language.) This
switching method does not always ensure that the proper
printer language is used, since the printer simply uses the
default language.
• Context Switching (HP Color LaserJet 4500 series,

automatically select a printer language (see the printer user's
manual), and the print job does not explicitly select a printer
language using the ENTER LANGUAGE command, the printer
samples the incoming data and looks for indications of a
