Defining The Backfeed Control Packet - Paxar 9402 Reference Manual

D e f i n i n g t h e B a c k f e e d C o n t r o l P a c k e t
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.
Extended backfeed is available on the 985x printers with a knife
installed. The 9860 printer always uses extended backfeed
operation whether it is selected or not. Extended backfeed
feeds a tag far enough out to be cut and backfeeds the next tag
to the printhead line. You can not change the backfeed distance
while the printer is active.
Extended backfeed eliminates printed tags
being left between the printhead and knife.
Extended backfeed does not work with
non-indexed (continuous) supply/mode.
Do not use backfeed (normal or extended) with supplies less than
0.75 inches. We recommend using 0.5-inch gap supplies in peel
mode when backfeed is disabled. Not all printers support peel
mode.
The 9403 printer does not support the backfeed packet. 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.
