[Details]
·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.
·If the ASB is enabled as a default, the printer transmits the status when the printer data
reception and transmission is possible at the first time from when
the printer is turned on.
·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:
