3 Enable Pre-Stock Out feature: This command supports the PSO
option and is used to detect stock out errors using an optional sensor
before the media enters the printer. Once enabled, when the PSO
(>INPUT 1<) sensor goes active the printer will finish printing the
current label, not cut it (if using a cutter command), then feed he stock
until it clears the dot row plus 1/2". At this point the normal stock out
function will be active and the printer status will respond with: >LOW
STOCK<>INPUT 1< (if the polarity of input one is set correctly).
4 Enable >STOCK NOT LOADED< Response: When enabled, the
printer will return >STOCK NOT LOADED< or 0x22 (depending on the
^D21 response mode configuration) to status requests if media is not
detected in the printer at power up. The status message will continue
to be reported until media is installed in the printer. This message will
only be reported if media is not detected by the internal sensors
following a power on, reboot command (^D143), and/or restart (^D32)
commands.

6 Select GP I/O Hardware Mode: This command is used to select
from the various General Purpose I/O modes the printer supports.
0 = Enable Custom General Purpose I/O Hardware. This mode is a
custom solution developed for a specific customer and is not intended
to be used by other users.
1 = Enable General Purpose I/O Hardware. When this command is
enabled, the printer provides the ability to report the current status of 4
additional inputs accessed through the P17 connector on the PCB,
report the status of 4 additional outputs accessed through the P21
connector on the PCB, to change the status of the outputs, and to
configure the inputs to generate immediate errors.
GP INPUTS:
The P17 connector is used for the GP inputs. These inputs are active
high (24VDC) and may be independently controlled.
The ^D150 command is used to report the current status of the inputs.
When issued, the printer will send the host the current status of the 4
general inputs in the form of ">IO 0nH< where "n" is a hex number from
0 to F.
Example: A status of >IO 05H< would indicate that inputs 1 and 3 are
active (24v) and that inputs 2 and 4 are inactive (0v); 05H =
0101(binary).
