9. STATUS RESPONSE
9.1 SERIAL INTERFACE
9.1.1 FUNCTIONS
There are the following two kinds of status response functions.
(1) Status transmission function at the end of normal transmission and occurrence of an error
(auto status transmission)
If the option for “status response” has been selected, the printer sends status to the host
computer when the printer performs a feed or completes an issue normally (For batch/cut
mode: after the designated number of labels are printed, For strip mode: after one label is
printed). In the online mode, the head up/down status is sent to the host computer.
When each error occurs, the status is sent to the host computer.
The remaining count in the status response indicates the remaining count of the batch
currently being printed. No remaining count of the batch waiting to be printed is transmitted.
(2) Status transmission function by status request (Status Request Command)
Upon request to send status by the Status Request Command, the printer sends the latest
status indicating its current state to the host computer, regardless of the option for “status
response/no status response” . The remaining count indicates the remaining count of the
batch currently being printed. No remaining count of the batch waiting to be printed is
transmitted. This command is not stored in the receive buffer and executed immediately
when it is received.
• Strip status
The strip status (05H) returned by the Status Request Command depends on the system
mode setting.
When the strip status of the system mode is set to “1”:
If the Status Request Command is sent when a label is on the strip shaft (for
example, while idling, after feeding a label, after printing all labels), the printer
returns (00H).
When the strip status of the system mode is set to “2”:
If the Status Request Command is sent when a label is on the strip shaft (for
example, while idling, after feeding a label, after printing all labels), the printer
returns (05H).
If the Status Request Command is sent while a label is being printed or issued, the strip
status (05H) is returned for both settings.
