Switching Between Printer Operating Modes

Intermec Printer Language (IPL) Developer's Guide
When you send IPL commands to the printer, make sure you have placed
the printer in the correct operating mode to interpret those commands:
• If you are sending print or configuration commands, the printer must
be in Print operating mode to interpret the commands.
• If you are sending program commands, the printer must be in Program
mode.
• If you are sending test and service commands, the printer must be in
Test and Service mode.
Print mode and Program mode are two different operating modes of the
printer. Before you download information to the printer, make sure that
you are in the correct mode:
• Use Program mode to define formats, pages, fonts, and characters.
• Use Print mode to print labels, to download data to the printer, to
download configuration commands to the printer, or to upload
information from an RFID tag.
To place a printer in Program mode
• Send this command string:
<STX><ESC>P<ETX>
Send this command every time that you download formats, even if you
think the printer is already in Program mode. If the printer is already in
Program mode, it ignores this command.
To place a printer in Print mode
• Send this command string:
<STX>R<ETX>
Send this command before each set of data or as your last format
command. If the printer is already in Print mode, it ignores this
command.
Note: The R command may be treated as data if the data to the printer does
not include a <CAN> or field pointer to clear the fields.
To place a printer in Test and Service mode
• Send this command string:
<STX><ESC>T<ETX>
Send this command before any test and service commands. Typically,
you will not need to use test and service commands when defining label
formats.
