Description:
This command changes the printer into the user setting mode.
Notes:
• If the printer is in standard mode, this command is valid only at the
beginning of the line.
• If the printer is in page mode, this command is ignored.
• Do not use this command while defining macros, because macros cannot
be included with this command.
• When the printer goes into the user setting mode, it transmits a “mode
change notice” back to the host.

• When it has executed this function, send the next commands after
checking the “mode change notice“.
• The host can differentiate the “mode change notice” from other data
the printer transmits by the specific information in the transmit data
block. When the header transmitted from the printer is 0x37 or 55
decimal, the data up to NUL (0x00 or 0 decimal) is handled as one group
and can be identified using the following data:
Transmit data Hex Decimal
1st byte (header) 0x37 55
2nd byte
(identifier)
0x20 32
However, consider the following requirement for data processing:
• When communication with the printer uses XON/XOFF control, the
XOFF code may interrupt the “Header to NUL” data string.
