[Notes] • This command is enabled only when processed at the beginning of a line in standard mode.
• This command is not effective in page mode.
• When this command is received during macro definition, the printer ends macro definition and
begins performing this command.
• The printer cuts the paper at the end of the test print.
GS ( E pL pH m [parameter]
[Name] User-defined commands
[Description] The user-defined commands control the values which are stored in the user NV memory.
The functions selected by m as below：
m Format Function
1 GS ( E pL pH m d1 d2 Enter user-defined mode
2 GS ( E pL pH m d1 d2 d3 End user-defined mode
3 GS ( E pL pH m [a1 b18 …b11]…[ak bk8…bk1] Sets the customized data of
memory switch
4 GS ( E pL pH m a Transmits the customized data in
the memory switch
• The number of bytes is specified by pL、pH is ( pL + ( pH 256)).
• m specifies the function
• d1、d2、d3 specifies the parameters to select the mode.
• a specifies the type of the stored data.
• bk8...bk1 specifies the value to be set to the stored data which is specified by a .
• In the Function 2, the printer performs the software reset. Therefore, the printer clears the receive
and print buffers, and resets all settings (user-defined characters, downloaded bit images, macros,
and the character style) to the mode that was in effect at power on.
[Notes] Frequent write command executions by a NV memory write command may damage the NV memory.
Therefore, it is recommended to write the NV memory 10 times or less a day.
