WS – Status Request Command
This command tells the printer to send its own status to the host computer.
The transmitted status is the current printer status, and indicates the latest
status only. The remaining count indicates the remaining batch count
currently being printed.
NOTE: The remaining batch count waiting to be printed is NOT transmitted.
Syntax:
ESC WS LF NULL
Parameters:none
Response Format:
See "Status Response" on page 12.
NOTE: The status request command is effective on serial (RS-232C) and
Ethernet interfaces only. Since the status cannot be sent via the
parallel interface (Centronics), this command is ignored.
After the code of the writable character command (XD) or the graphic
command (SG) is received, the status request command is not
processed until the printer receives the data type.
XB – Barcode Format
This command formats barcode fields. The location coordinates are specified
in 1/10 mm units. Many parameters of the barcode can be configured, like bar
and space widths, if and how the PDF must be printed, etc. The barcode
types listed in Table 2 can be printed. Data to be printed can be included in
this command or supplied separately through the RB command.
