1. Printing Using Raster Commands
(1) Open the USB/serial/network port
Open the USB/serial/network port in the operating environment. The procedure for opening the
USB/serial/network port is not described in this material.
The network port can only be used with the RJ-4040.
(2) Confirm the printer status sent from the printer
The “status information request” command is sent to the printer, the status information received from the
printer is analyzed, and then the status of the printer is determined.
For details on the “status information request” command and on the definitions of “status”, refer to “Status
information request” in “
(3) Send the print data
If the status analysis confirms that media compatible with the print data is loaded into the printer and that
no error has occurred, the print data is sent.
The structure of the print data is explained in the next section, “
Note:
No command can be sent to the printer after the print data is transmitted and until the completion
of printing is confirmed.
Even the “status information request” command cannot be sent during printing.
(4) Print the data
(5) Confirm that printing is completed
When printing is completed, the status is received from the printer.
If this status is analyzed to confirm that printing is completed, printing one page is considered finished.
If the print job has multiple pages, (2) through (4) are repeated.
(6) Close the USB/serial/network port
After all printing is finished, close the USB/serial/network port.

Brother RJ-XXXX starts printing when it starts to receive print data, instead of waiting for a print
command (concurrent printing).
For the processing flow,
for example when managing errors, refer to “
