Yes, with iPhone and our USB scanners we are able to scan that “wider” bars, but i am not sure the highspeed scanners of the carrier can.
The packages are scanned by high speed scanners while they are carried and sorted on a“tractor tapes”. Btw, us tractor tape the correct expression?
If the thermal transfer labels are accepted by the carrier then i will add an option for the user to switch between laser and thermal printing. The app will use different settings for laser and thermal printing.
So in case the TT printer is broken, they can switch over the laser printer.
