[Notes]
■
The value of parameter
fn
determines the function number for this command. Command operation
differs, depending on the function number.
■
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
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 ( A
(part of functions), GS
( C
(part of functions),
GS ( E
(part of
functions),
GS ( L
/
GS 8 L
(part of functions),
GS ( M
(part of functions)
,
GS g 0
,
and
FS g 1
.
[Notes for transmission process]
■
Data is transmitted by Functions 1, 4, 6, 12, and 50. When you use these functions, obey the following
rules.
•
When the host PC transmits the function data, transmit the next data after receiving the corresponding
data from the printer.
•
With a serial interface printer, be sure to use this function when the host can receive data.
