User setting mode is a special mode to change settings for the printer's built-in non-volatile memory.
To change a setting, you must change the printer into user setting mode, using Function 1.
Execute function 2 of this command after making the setting. The setting value is effective after executing
the software reset of function 2.
Note the rules below for the user setting mode:
• The printer does not process character data.
• The printer does not process commands other than this command and the GS I command.
• The printer does not process real-time commands.
• The printer does not transmit ASB status.
Functions 4, 6, 12, and 50, the functions used to transmit the current settings to the host, can be used at
any time, without changing into the user setting mode.
Data is written to the non-volatile memory by Functions 3, 5, 7, 11, 48, and 49. Note the following when
using those functions:
• The printer might be BUSY. In this case, be sure not to transmit a command from the host because the
• Excessive use of this function may destroy the non-volatile memory. As a guideline, do not use any
