RP-U420 Miscellaneous commands DLE DC4
Ver. 1.0
p. 77
This command should not be used within the data sequence of another command that consists of two or
more bytes.
<Example>
If you attempt to transmit ESC !
n
to the printer, but DLE DC4 105 interrupts before
n
is received, the
code <10>H for DLE DC4 is processed as the code for ESC ! <10>H.
This command is enabled even when the printer is not selected by ESC =.
If the printer receives this command during outputting pulse required by ESC p or DLE DC4 to the same
connector pin, this command will be ignored.
If the printer receives this command during outputting pulse required by ESC p or DLE DC4 to another
connector pin, this command will be queued and executed afterward.
Program Example
PRINT #1, CHR$(&H10);CHR$(&H14);CHR$(1)l;CHR$(0);CHR$(5);
