STATUS REQUEST COMMAND
Printer status and response are returned to the host computer as statuses when a request or print command is
received. When the status request command is received, the job ID number of the reception data currently being
printed, the printer status, the quantity of labels yet to be printed, and the job name are returned to the host
computer. When printing is complete or if there isn’t reception data, all zeros (hexadecimal 30H) is returned for
printing count. If a job Id number has not been designated, a space (hexadecimal 20H) is returned for the job ID
number.
Figure 6, Command Stream Structure
NOTE: Do not execute a status enquiry (ENQ) while print data is being sent
(STX...ETX) because that status may not be returned or printing not be carried out.
