3.3.2 Return Status in Protocol for Driver (STATUS4) Format
In STATUS4 format, the printer returns the printer status and response status to the host computer by receiving
four types of request commands. When the combination of RS-232C interface and STATUS4 is used, the printer
status will be returned to the host computer by receiving the print command.
The details of each request command and return status are as follows.
1) Status request command
This command returns the job ID number of receive data that is currently printing, the printer status, the number of
remaining labels and the job name to the host computer. When the print is completed or when there is no receive
data, all “0” (HEX 30H) will be returned for the print quantity. If the JOB ID Number command is not specified, the
printer will respond with “space” character (HEX 20H) for the job ID number.
(1) Command ENQ(HEX 05H)
(2) Return status format
Note that return status format is different depending on the interface to be used (e.g. LAN , other interfaces).
* Important
Avoid ENQ transmission (status request) while sending the print data (STX…ETX).
Failure to do so may result in return status error or print error.
