If any of the status items in the table above are enabled, the printer transmits the status
when this command is executed. The printer automatically transmits the status
whenever the enabled status item changes. The disabled status items may change, in
this case, because each status transmission represents the current status.
If all status items are disabled, the ASB function is also disabled.
The following four status bytes are transmitted without confirming whether the host is
ready to receive data. The four status bytes must be consecutive, except for the XOFF
code.
Since this command is executed after the data is processed in the receive buffer, there
may be a time lag between data reception and status transmission.
When the printer is disabled by
ESC =
(Select peripheral device), the four status bytes
are transmitted whenever the status changes.
When using
DLE EOT
,
GS I
, or
GS r
, the status transmitted by these commands and
ASB status must be differentiated.
The status to be transmitted are as follows:
