2-16 Packet Reference Manual
Defining the Backfeed Control Packet
Use the backfeed control packet (G) to enable or disable the backfeed option, set the dispense
position and the backfeed distance. Backfeed works by advancing each printed label to the
desired dispense position. Once that label is removed, the next label to be printed is backed up
underneath the printhead. In continuous mode, only the last label in the batch is advanced to the
dispense position. You may need to adjust the dispense position to allow labels to be removed,
die cut labels to be removed easily, or to prevent them from falling off.
Do not use backfeed with supplies less than 0.75 inches. We recommend using 0.5-inch gap
supplies in peel mode when backfeed is disabled.
The dispense position and backfeed distance are optional parameters and do not have to be
specified. However, they allow for greater precision when positioning the supply.
Syntax {I,G,action,dis_pos,bkfd_dis | }
G1. G Backfeed Control Packet
G2. action Action. 0 is the default. Options:
0 disable backfeed
1 enable backfeed
G3. dis_pos Dispense Position. Adjusts the stopping point of the label. Range: 50
to 200 dots. 65 is the default.
G4. bkfd_dis Backfeed Distance. Amount to move label backwards. 20 to 200 dots.
65 is the default. 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,1,50,20 | }
Enables backfeed and sets the dispense position to 0.25 inches (50/203) and the backfeed
distance to 0.10 inches (20/203).
