GS ( E pL pH fn [parameters]
[Name] Set user setup commands
[Description] • Controls the user setting modes.
• pL, pH specify (pL + pH ×256) as the number of bytes after pH (fn and [parameters]).
• fn specifies the function.
• [parameters] specify the process of each funct ion.
fn Format Function
No. Function name
1 GS ( E pL pH fn d1 d2 1 Change into the user setting mode.
2 GS ( E pL pH fn d1 d2 d3 2 End the user setting mode session.
5 GS ( E pL pH fn
[a1 n1L n1H] ... [ak nkL nkH] 5 Set the customized setting values.
6 GS ( E pL pH fn a 6 Transmit the customized setting v alues.
11 GS ( E pL pH fn a d1...dk 11 Set the configuration it em for the serial
interface.
12 GS ( E pL pH fn a 12 Transmit the configuration item for the
serial interface.
[Notes] • Frequent write com mand executions by an NV memory write com mand may damage
the NV memory. Therefore, it is recommended t o write to the NV memory less than
10 times a day.
• If the power is turned off or the printer is reset via an interf ace while this command is
being executed, the printer may go int o an abnor m al condition. Be careful not to
turn the power off or let the printer be reset v ia an interface while this com m and is
being executed.
• While processing thi s com mand, the printer is BUSY while writing t he data to the NV
memory and stops receiving data. Therefore, be sure not to t ransmit data, including
the real-time commands, while t he pr i nter is BUSY.
• When <Function 1, 6, or 12> is transmitted, the data fol l owing must not be
transmitted until the status is receiv ed.
