• The value defined by the user setting mode is effective until redefined
by this mode again. It is not initialized by turning off the power or
executing ESC @.
User setting mode is a special mode to change settings for the printer’s
built-in non-volatile memory.
• To change a setting, you mus
t change the printer into user setting mode,
using Function 1.
• The setting you specify is activated by transmitting a Function 2
command upon completion of making the setting.
• 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 ignores 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 printer will not receive the data.
• Excessive use of this function may destroy the non-volatile memory. As
a guideline, do not use any combination of the following commands
more than 10 times per day for writing data to the non-volatile memory:
FS q, GS ( E (part of functions), GS ( L (part of functions), GS g 0, and FS g
1.
• Notes for the processing to transmit data:
• Data is transmitted by Functions 1, 4, 6, 12, and 50.
• The printer goes BUSY immediately before transmitting the header,
and it returns to READY after transmitting NUL. (This excludes situations
when the printer is BUSY for other reasons.)
• You cannot use ASB status and real-time commands while “Header to
NUL” data is being transmitted.
• With a serial interface printer, be sure to use this function when the
host can receive data.
• With a parallel interface printer, data transmitted (excluding ASB
status) with this command (“Header to NUL”) is temporarily stored in
the printer transmit buffer, as with other data. When the host goes into
reverse mode, the printer then transmits the data sequentially from the
beginning of the transmit buffer. Transmit buffer capacity is 99 bytes.
Data exceeding this amount is lost. Therefore, when using this
command, promptly change into reverse mode to start the data receive
process.
