7 Select PIC Mode: This command is used to select from the various PIC
modes the printer supports. The PIC code is dedicated to the take-up
motor or the cutter.
0 = Select Cutter PIC mode of operation. When this mode is
selected the printer will power and energize a cutter when the cutter
enable command (^D99 or ^D111) is issued after a print job
1 = Select Take-up PIC mode of operation. When this mode is
selected the printer will energize a DC motor to be used in a rewind or
take up capacity. Unless the printer is properly configured with a take-
up motor and correct take-up motor specific PIC, this mode should not
be enabled because it could potentially damage the cutter.
