Shared Printer Language
Perform these steps by sending specific commands from your
computer to your printer. For step
1,
always send the universal exit
command:
<ESC>, <SOH>
Next you must immediately send an EJL command. For example,
you can enter
LQ
mode by sending the following:
“@ EJL ENTER LANGUAGE = LQ”, < LF >
Therefore, you need to send the commands below to switch to the
LQ
mode:
ESC, SOH, @EJL ENTER LANGUAGE = LQ, < LF >
The printer mode indicated on the display changes to the new one.
Overview of the EJL commands
EJL commands must be sent immediately after the printer
receives the universal exit command; otherwise, the printer
returns to its default printer mode.
Every EJL command starts with the following string: @EJL,
which must be in uppercase letters, although other commands
can be in both upper and lower case.
You must send the LF code at the end of an EJL command;
only an LF code terminates the EJL command. If the EJL
command is not followed by an LF code, the printer does not
recognize it as an EJL command; it is then printed as a
character string in the current printer mode.
If you are in EPSON GL mode, you cannot exit with the
universal exit command. You must switch modes with
SelecType.
