Example:
Using the ENTER
Command
To select the ESC/P personality, always be sure to use the
@PJL ENTER LANGUAGE = ESCP command to explicitly
select it.
For any job containing personality-specific data, send the
ENTER command if the intended printer language is
known, instead of relying on the printer's ability to switch
to the default printer language. This is true even if there is
only one available personality.
When a printer language is specified, that language
currently must be installed in the printer. If the printer
receives a request for an invalid printer language, the
printer consumes the data stream until it finds the next
UEL command, and then discards the data. The printer
also posts an "invalid personality" clearable warning
message (W2 INVALID PERS) and, if enabled, returns a
status message.
In spooling applications, performance is not adversely
affected if both the application file and the spooler send
the ENTER command.
