CHAPTER 5 PJL - 11
If the printer receives this command, it immediately executes the specified operation.
If this command specifies an operation which is not supported, this command is ignored.
Example
<ESC>%-12345X@PJL<CR><LF>
@PJL EXECUTE DEMOPAGE <CR><LF>
<ESC>%-12345X
4.4. ENTER Command
The ENTER command specifies which emulation the printer uses to print data.
Syntax
@PJL ENTER LANGUAGE = emulation [<CR>]<LF>
Parameters
emulation
The variables depend on the printer model.
The ENTER command must be placed immediately before print data.
The specified emulation will be used immediately after the terminating <LF> of the ENTER command.
If the printer does not receive the ENTER command, it uses the default printer language which is set by the
control panel or the printer language which is set by the SET PERSONALITY command.
When a printer emulation is selected by the ENTER command, the printer must switch to the defined printer
language.
If this command specifies an emulation which is not supported, data after this command is ignored until the
next UEL command.
Example
<ESC>%-12345X@PJL<CR><LF>
@PJL ENTER LANGUAGE = PCL <CR><LF>
<ESC>E.......PCL JOB........<ESC>E
<ESC>%-12345X

Parameters

The COMMENT command is helpful for placing an explanation of a PJL command.

ENTER command.
The COMMENT command is terminated by <LF>.
Comments can only be one line long. If you wish to add more text, start a new comment line.
