4. "STX Vn" COMMAND. SETTING THE PSEUDO SWITCHES.
Switch SW1, mounted on the back of the Printer, is read on power-
up or on soft reset. The positions of switches 5 through 8 can be
modified through this command. Send "STX Vn" where "n" is a
hex value of 0 to F to define the settings.

*This setting is of no value.
5. "M####" COMMAND. SETTING THE MAXIMUM LABEL SIZE.
The Printer was designed to accept labels with a maximum length of
99.99". The maximum label size can be reduced by sending the
Printer a "M####" command where the numbers 0 to 9 represent the
maximum length of the label. "####" is expressed to the nearest
1/100th of an inch; decimal place removed.
This command is a nice feature while designing labels. It prevents
the Printer from feeding out tremendously long strips of media if an
error is made by the host device. The Printer defaults to a value of
"1200".
It is recommended that the label-out value be set to 2.5 times the
actual label length that is being used. This will allow for a label to
be missing on a roll without stopping the printing.
