G1. G Backfeed Control Packet
G2. action Action. Options:
0 disable backfeed (default)
1 enable backfeed
G3. dis_pos Dispense Position. Adjusts the stopping point of the label. 10 to 200 dots
(default 65 dots).
G4. bkfd_dis Backfeed Distance. Amount to move label backwards. 10 to 200 dots
(default 65 dots). 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.
Example
{ I,G,1,50,10 p }
Enables backfeed and sets the dispense position to 0.25 inches (50/203)
and the backfeed distance to 0.05 inches (10/203).

Make a note of the following items:
¨ Be careful when tearing supplies, because the adhesive can adhere to
the printhead or platen roller.
¨ Backfeed effects each label in the on-demand mode or the first and last
label of the batch in continuous mode.
¨ When backfeed is enabled and multiple batches are sent, the printer may
not backfeed between each batch.
¨ Backfeed should only be used when you need to advance labels to the
desired dispense point.
¨ Backfeed does not interfere with the supply, print, or margin positions
you have set.
¨ If the supply inter-label gap is not between .07 inch to .15 inch (14 to 30
dots), you must adjust the dispense position and backfeed distance
accordingly.
