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.

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. You can’t change the backfeed distance while the printer is active.

Syntax

{I,G,action,dis_pos,bkfd_dis p }

G1. G

Backfeed Control Packet

G2. action

Action. Options:

 

0

disable backfeed (default)

 

1

enable backfeed (use on any printer without a knife)

G3. dis_pos

Dispense Position. Adjusts the stopping point of the label. 0

 

or 10 - 200 dots (default 65 dots).

G4. bkfd_dis

Backfeed Distance. Amount to move label backwards. 0 or

 

10 - 200 dots (default 65 dots). Cannot 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 40 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).
