Syntax
G1. G
G2. action
G3. dis_pos
G4. bkfd_dis
Example
Enables extended backfeed and cuts any tags remaining between
the knife and printhead and moves the supply backwards so the
next tag is underneath the printhead. Using cut mode 4, you do
not have to press FEED (FEED/CUT) to cut the last tag.
Example
Enables backfeed and sets the dispense position to 0.25 inches
(50/203) and the backfeed distance to 0.05 inches (10/203).

Backfeed Control Packet
Action. Options:
0 disable backfeed (default)
1 enable backfeed (use on any printer without a knife)
2 enable extended backfeed (use on any printer with
a knife)
Dispense Position. Adjusts the stopping point of the label. 50
to 200 dots (default 65 dots). Use 95 dots for the printer
applicator.
Backfeed Distance. Amount to move label backwards. 10 to
200 dots (default 65 dots). Use 95 dots for the printer
applicator. This distance can not be greater than the
dispense position.
The backfeed distance should equal the dispense position.
An exception is if you are tearing instead of peeling. Then,
the backfeed distance must be 30 dots (.150 inches) less than
the dispense position. However, you will have a 30 dot
non-print zone on your supply. The 30-dot difference
accounts for improper tearing of butt cut supplies, because
you do not want any exposed adhesive under the printhead.
