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 powerup. 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).
The ^D151 is a nonvolatile command used to set which GP inputs are
configured to cause an immediate error when active. An immediate
error will immediately stop printing and go into an error condition. Once
